108-561: Milkwall is a village in the Forest of Dean in Gloucestershire , England. It lies between the village of Sling to the south, and the town of Coleford to the north. Milkwall, strictly speaking, lies South of Station Rd in the parish of West Dean, whereas Tufthorn is North of Station Rd in the parish of Coleford. Near Milkwall is Perrygrove Railway – a private heritage railway, and Puzzlewood – an ancient woodland site. There

216-478: A "pit", and above-ground mining structures are referred to as a " pit head ". In Australia , "colliery" generally refers to an underground coal mine. Coal mining has had many developments in recent years, from the early days of men tunneling, digging, and manually extracting the coal on carts to large open-cut and longwall mines. Mining at this scale requires the use of draglines , trucks, conveyors , hydraulic jacks , and shearers. The coal mining industry has

324-697: A 70% increase over the 20 years since 1999. In 2018, the world production of brown coal (lignite) was 803.2 Mt, with Germany the world's largest producer at 166.3 Mt. China is most likely the second largest producer and consumer of lignite globally although specific lignite production data is not made available. Coal production has grown fastest in Asia, while Europe has declined. Since 2011, world coal production has been stable, with decreases in Europe and US offset by increases from China, Indonesia and Australia. The top coal mining nations are: Energy production from coal mining

432-467: A coal seam occurring near the top of a ridge or hill, the entire top is removed in a series of parallel cuts. Overburden is deposited in nearby valleys and hollows. This method usually leaves the ridge and hilltops as flattened plateaus. The process is highly controversial for the drastic changes in topography, the practice of creating head-of-hollow-fills , or filling in valleys with mining debris, and for covering streams and disrupting ecosystems. Spoil

540-405: A fourth of the world's energy. Coal extraction methods vary depending on whether the mine is an underground mine or a surface (also called an open cast) mine. Additionally, coal seam thickness and geology are factors in the selection of a mining method. The most economical method of coal extraction for surface mines is the electric shovel or drag line. The most economical form of underground mining

648-403: A greater proportion of the coal deposit than underground methods, as more of the coal seams in the strata may be exploited. This equipment can include the following: Draglines which operate by removing the overburden, power shovels, large trucks in which transport overburden and coal, bucket wheel excavators, and conveyors. In this mining method, explosives are first used in order to break through

756-440: A land use condition is not equal to the original use. Existing land uses (such as livestock grazing, crop and timber production) are temporarily eliminated in mining areas. High-value, intensive-land-use areas like urban and transportation systems are not usually affected by mining operations. If mineral values are sufficient, these improvements may be removed to an adjacent area. Strip mining eliminates existing vegetation, destroys

864-440: A large dining-room table, but with hydraulic jacks for legs. After the large pillars of coal have been mined away, the mobile roof support's legs shorten and it is withdrawn to a safe area. The mine roof typically collapses once the mobile roof supports leave an area. There are six principal methods of underground mining: Coal is mined commercially in over 50 countries. 7,921 million metric tons (Mt) of coal were produced in 2019,

972-559: A long history of significant negative environmental impacts on local ecosystems, health impacts on local communities and workers, and contributes heavily to the global environmental crises, such as poor air quality and climate change . For these reasons, coal has been one of the first fossil fuels to be phased out of various parts of the global energy economy . The major coal producing countries, though, such as China , Indonesia, India and Australia , have not reached peak production, with production increases replacing falls in Europe and

1080-447: A method that currently accounts for about 60 percent of world coal production. In deep mining, the room and pillar or bord and pillar method progresses along the seam, while pillars and timber are left standing to support the mine roof. Once room and pillar mines have been developed to a stopping point limited by geology, ventilation, or economics, a supplementary version of room and pillar mining, termed second mining or retreat mining ,

1188-453: A network of railways, and numerous tramroads. The tradition of independence in the area resulted in a great number of smaller and not necessarily economically successful mines. In 1904 the Gaveller oversaw a period of amalgamation of collieries which allowed deeper mines to be sunk. During the early 20th century, annual output from the coalfield rarely fell below 1 million tons. In 1945 half of

1296-458: A number of industrial areas but the focus has been to capitalise on the scenery and to create jobs from tourist attractions and the leisure sector. Significant numbers of residents work outside the area, commuting to Gloucester , Cheltenham , Bristol , Newport and Cardiff . The Forest of Dean is formed of a raised basin of palaeozoic rocks folded in the Variscan Orogeny , similar to

1404-574: A result of occupational exposures is coined occupational hearing loss . To protect miners' hearing, the US Mine Safety and Health Administration 's (MSHA) guidelines for noise place a Permissible Exposure Limit (PEL) for noise at 90 dBA time-weighted over 8 hours. A lower cutoff, 85 dBA, is set for a worker to fall into the MSHA Action Level which dictates that workers be placed into hearing conservation programs. Noise exposures vary depending on

1512-534: A week later. A total of £85 (equivalent to £11,900 in 2023) was paid in fines. A subscription was also launched which generously compensated the Frenchmen. The term "Who killed the bears?" existed for many years as an insult, directed particularly towards the people of Ruardean – despite the fact that all those convicted were from Cinderford. A fictional version of the incident was used by Dennis Potter for his TV play A Beast With Two Backs . Exploitation of

1620-486: Is oak , both pedunculate and sessile . Beech is common and sweet chestnut has grown here for many centuries. The forest is home to foxgloves and other wild flowers. Conifers include some Weymouth pine from 1781, Norway spruce , Douglas fir and larch . The deer are predominantly fallow deer and have been present since the second world war (there were no deer from about 1855 when they were removed in accordance with an Act of Parliament). A number of fallow deer in

1728-580: Is a geographical, historical and cultural region in the western part of the county of Gloucestershire , England. It forms a roughly triangular plateau bounded by the River Wye to the west and northwest, Herefordshire to the north, the River Severn to the south, and the City of Gloucester to the east. The area is characterised by more than 110 square kilometres (42 sq mi) of mixed woodland, one of

1836-575: Is accomplished by drilling holes into the overburden, filling the holes with explosives, and detonating the explosive. The overburden is then removed, using large earth-moving equipment, such as draglines , shovel and trucks, excavator and trucks, or bucket-wheels and conveyors. This overburden is put into the previously mined (and now empty) strip. When all the overburden is removed, the underlying coal seam will be exposed (a 'block' of coal). This block of coal may be drilled and blasted (if hard) or otherwise loaded onto trucks or conveyors for transport to

1944-581: Is archaeological evidence of early trading by sea, probably through Lydney . Before Roman times, the area may have been occupied by the British Dobunni tribe, although few of their coins have been found in the area and control may have been contested with the neighbouring Silures . The area was occupied by the Romans in around AD 50. They were attracted by its natural resources which included iron ore , ochre and charcoal . The coal mining industry

2052-427: Is commonly started. Miners remove the coal in the pillars, thereby recovering as much coal from the coal seam as possible. A work area involved in pillar extraction is called a pillar section. Modern pillar sections use remote-controlled equipment, including large hydraulic mobile roof-supports, which can prevent cave-ins until the miners and their equipment have left a work area. The mobile roof supports are similar to

2160-418: Is dedicated to mining activities until it can be reshaped and reclaimed. If mining is allowed, resident human populations must be resettled off the mine site; economic activities, such as agriculture or hunting and gathering food and medicinal plants are interrupted. What becomes of the land surface after mining is determined by the manner in which the mining is conducted. Usually reclamation of disturbed lands to

2268-516: Is highly concentrated in certain jurisdictions, which also concentrates much of the social and economic impacts of the industry to these regions. The industry directly employs over seven million workers worldwide, which, in turn, creates millions of indirect jobs. In several parts of the world, producers have reached peak coal as some economies shift away from fossil fuels to address climate change. A 2020 study found that renewables jobs could feasibly be created in these geographies to replace many of

2376-479: Is mostly used to generate electricity, and 75% of annual coal production is exported, mostly to eastern Asia. In 2007, 428 million tonnes of coal was mined in Australia. In 2007, coal provided about 85% of Australia's electricity production. In the fiscal year 2008/09, 487 million tonnes of coal was mined, and 261 million tonnes was exported. In the fiscal year 2013/14, 430.9 million tonnes of coal

2484-446: Is necessary. Under its international obligations the UK government is obliged to consider the reintroduction of species made extinct through the activities of man, the wild boar included. The Forest of Dean is known for its woodland birds; pied flycatchers , redstarts , wood warblers , lesser spotted woodpecker , nightjars and hawfinches can be seen at RSPB Nagshead and other parts of

2592-417: Is partially economically recoverable. Coal refuse is distinct from the byproducts of burning coal, such as fly ash . Piles of coal refuse can have significant negative environmental consequences, including the leaching of iron, manganese, and aluminum residues into waterways and acid mine drainage . The runoff can create both surface and groundwater contamination. The piles also create a fire hazard, with

2700-593: Is placed at the head of a narrow, steep-sided valley or hollow. In preparation for filling this area, vegetation and soil are removed and a rock drain constructed down the middle of the area to be filled, where a natural drainage course previously existed. When the fill is completed, this underdrain will form a continuous water runoff system from the upper end of the valley to the lower end of the fill. Typical head-of-hollow fills are graded and terraced to create permanently stable slopes. Most coal seams are too deep underground for opencast mining and require underground mining,

2808-436: Is referred to as 'overburden' and is removed in long strips. The overburden from the first strip is deposited in an area outside the planned mining area and referred to as out-of-pit dumping. Overburden from subsequent strips is deposited in the void left from mining the coal and overburden from the previous strip. This is referred to as in-pit dumping. It is often necessary to fragment the overburden by use of explosives. This

2916-515: Is removed and overburden dumped to the side. Dust, vibration, and diesel exhaust odors are created (affecting sight, sound, and smell). Residents of local communities often find such impacts disturbing or unpleasant. In case of mountaintop removal , tops are removed from mountains or hills to expose thick coal seams underneath. The soil and rock removed is deposited in nearby valleys, hollows and depressions, resulting in blocked (and contaminated) waterways. Removal of soil and rock overburden covering

3024-701: Is still common, with 4,000 new cases of black lung every year in the US (4 percent of workers annually) and 10,000 new cases every year in China (0.2 percent of workers). The use of water sprays in mining equipment reduces the risk to miners' lungs. Build-ups of a hazardous gas are known as damps, possibly from the German word Dampf which means steam or vapor: Noise is also a contributing factor to potential adverse effects on coal miners' health. Exposure to excessive noise can lead to noise-induced hearing loss . Hearing loss developed as

3132-464: Is the long wall, which involves using two spinning drums with carbide bits that runs along sections of the coal seam. Many coals extracted from both surface and underground mines require washing in a coal preparation plant . Technical and economic feasibility are evaluated based on the following: regional geological conditions; overburden characteristics; coal seam continuity, thickness, structure, quality, and depth; strength of materials above and below

3240-463: Is the process of extracting coal from the ground or from a mine. Coal is valued for its energy content and since the 1880s has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa , a coal mine and its structures are a colliery , a coal mine is called

3348-435: Is used for both thermal and metallurgical coals . In New South Wales open casting for steam coal and anthracite is practiced. Surface mining accounts for around 80 percent of production in Australia, while in the US it is used for about 67 percent of production. Globally, about 40 percent of coal production involves surface mining. Strip mining exposes coal by removing earth above each coal seam. This earth to be removed

It was the first true tool steel and the first air-hardening steel . It revolutionised the design of machine tools and the progress of industrial metalworking, and was the forerunner of High speed steel . The remains of Darkhill are preserved as an Industrial Archaeological Site of International Importance and are open to

3564-512: The Dean Forest Railway between Lydney Junction and Norchard is now a heritage railway . The Gloucester-Newport line continues to carry passengers. Lydney railway station serves the Forest of Dean, with 0.196 million passenger entries and exits in 2017–18. The station is served by trains operated by Transport for Wales , linking the Forest directly to Cheltenham and Gloucester to

3672-506: The Forest of Dean Coalfield developed rapidly in the early 19th century with increased demand from local ironworks, and when some of the earliest tramroads in the UK were built here to transport coal to local ports the area was transformed by the growth of mining and the production of iron and steel. In 1818–19 David Mushet built Darkhill Ironworks , where he experimented with iron and steel making. In 1845, his youngest son, Robert Forester Mushet , took over its management. He perfected

3780-482: The Industrial Revolution , and coal provided the main source of primary energy for industry and transportation in industrial areas from the 18th century to the 1950s. Coal remains an important energy source. Coal is also mined today on a large scale by open pit methods wherever the coal strata strike the surface or are relatively shallow. Britain developed the main techniques of underground coal mining from

3888-572: The South Wales Railway at Bullo Pill . The less successful Forest of Dean Central Railway attempted to compete with the other lines for coal traffic but was rendered obsolete by the opening of the Mineral Loop, a new line opened by the Severn & Wye to connect a number of pitheads. Most of these railways now cease to exist, with most of the railways in the Forest abandoned by 1968. A section of

3996-511: The South Wales coalfield to the west. Underlain by great thicknesses of the Old Red Sandstone , the basin is filled with Carboniferous limestones , sandstones and coal measures , all of which have contributed to the industrial history of the region. Its highest point is Ruardean Hill (290 m, 950 ft). The forest is composed of deciduous and evergreen trees. Predominant

There were engineering works at Milkwall belonging in 1889 to Tom Morgan which continued casting metals after World War I . A colour ( pigment ) factory was started at Milkwall in 1926 – it employed 7 people in 1965, when in addition to processing oxides mined elsewhere it ground coal for use in

4212-631: The Commoners Association. In October 2010 a woman won the right to be classified as a Freeminer. Elaine Morman, an employee at Clearwell Caves in the Forest, who had worked as a miner of ochre for a number of years, raised a claim of sexual discrimination against the Forestry Commission . After Mark Harper MP raised the matter in the House of Commons , the Forestry Commission reversed its position and agreed to register her. The forest

4320-620: The Forest of Dean was disafforested in the 1620s, causing a series of riots in 1631–32; this was part of enclosure riots across the South West commonly known as the Western Rising. In 1639 22,000 acres (8,900 ha) were disafforested, with 4,000 acres (1,600 ha) going to manorial lords and freeholders in compensation. 18,000 acres (7,300 ha) were to go to the Crown, and be sold on to Sir John Winter . Riots ensued in 1641. Winter's claim to

Over the next few days more troops arrived from around the country. The Foresters' resistance crumbled and most of those arrested elected to rebuild the enclosures, rather than be charged with rioting. James was sentenced to death but his sentence

4536-575: The Hundred of St Briavels supported King Edward I at the siege of Berwick-on-Tweed in the Scottish Wars of Independence by undermining the then Scottish town's defences in the first step of his campaign to seize Scotland from John Balliol . As a result, the king granted free mining rights within the forest to the miners and their descendants; the rights continue to the present day. Miners at that time were mainly involved in iron ore mining – although

4644-533: The Speech", a sort of parliament for the Verderers and Free Miners managing the forest, game, and mineral resources. The Gaveller and his deputy were responsible for leasing gales – areas allocated for mining – on behalf of the Crown. The Speech House has been used as an inn and hotel since the 19th century. The Forest of Dean, with its huge iron ore reserves and ready supply of timber, had been of national importance in

4752-787: The U.S., Examples include the Sago Mine disaster of 2006, and the 2007 mine accident in Utah 's Crandall Canyon Mine , where nine miners were killed and six entombed. In the decade 2005–2014, US coal mining fatalities averaged 28 per year. The most fatalities during the 2005–2014 decade were 48 in 2010, the year of the Upper Big Branch Mine disaster in West Virginia, which killed 29 miners. Chronic lung diseases, such as pneumoconiosis (black lung) were once common in miners, leading to reduced life expectancy . In some mining countries black lung

4860-428: The UK national target for clean air, set at 40 μg/m ( micrograms per cubic metre ). In 2017, no roadside monitoring site in the Forest of Dean District failed to meet the UK objective. The most polluted site measured was on Lydney High Street, with a 2017 average NO 2 concentration of 36.9 μg/m . The Forest of Dean once boasted a developed railway network, much of which evolved from plateways built in

4968-608: The US Department of Labor's Mine Safety and Health Administration (MSHA) show that between 1990 and 2004, the industry cut the rate of injuries by more than half and fatalities by two-thirds. But according to the Bureau of Labor Statistics , even in 2006, mining remained the second most dangerous occupation in America, when measured by fatality rate . These numbers, however, include all mining activities, and oil and gas mining contribute to

5076-660: The United States and proposed mines under development. The coal mining industry employs almost 2.7 million workers. The History of coal mining goes back thousands of years, with early mines documented in ancient China, the Roman Empire and other early historical economies. It became important in the Industrial Revolution of the 19th and 20th centuries, when it was primarily used to power steam engines, heat buildings and generate electricity. Coal mining continues as an important economic activity today, but has begun to decline due to

5184-722: The Viking settlements in that era. It is possible that an original name Dene developed from this. The area was inhabited in Mesolithic times, and there are also remains of later megalithic monuments, including the Longstone near Staunton and the Broadstone at Wibdon, Stroat . Barrows have been identified at Tidenham and Blakeney . Bronze Age field systems have been identified at Welshbury Hill near Littledean , and there are Iron Age hill forts at Symonds Yat and Welshbury. There

5292-683: The area came under Anglo-Saxon control, the Forest of Dean remained under the auspices of the diocese of Hereford , rather than Gloucester. The Beachley and Lancaut peninsulas east of the Lower Wye remained in Welsh control at least until the 8th century. Around 790 the Saxon King Offa of Mercia built his dyke high above the Wye, but the area was still claimed by the Kingdom of Gwent and Morgannwg before it

5400-435: The bears had killed a child and injured a woman. The bears were killed and the Frenchmen badly beaten. It soon became clear that the bears had not attacked anyone. Police proceedings followed and a week later 13 colliers and labourers appeared before magistrates at Littledean, charged with ill-treating and killing the bears and assaulting the Frenchmen. All but two were found guilty on one or more charges, with another convicted

5508-507: The central area are melanistic . Small numbers of roe deer and muntjac deer have spread in from the east. The Forest is also home to wild boar . A population in the Ross-on-Wye area on the northern edge of the forest escaped from a wild boar farm around 1999 and are believed to be of pure Eastern European origin; in a second introduction, a domestic herd was dumped near Staunton in 2004, but are not pure bred wild boar. Attempts to locate

5616-581: The coal mining jobs as part of a just transition ; however, renewable energy was not suitable in some of the geographies with high concentrations of miners, such as in China, which is far and away the leading coal-mining nation. Coal refuse (also described as coal waste, rock, slag, coal tailings, waste material, rock bank, culm, boney, or gob ) is the material left over from coal mining, usually as tailings piles or spoil tips . For every tonne of hard coal generated by mining, 400 kg (880 lb) of waste material remains, which includes some lost coal that

5724-497: The coal preparation (or wash) plant. Once this strip is empty of coal, the process is repeated with a new strip being created next to it. This method is most suitable for areas with flat terrain. Equipment to be used depends on geological conditions. For example, to remove overburden that is loose or unconsolidated, a bucket wheel excavator might be the most productive. The life of some area mines may be more than 50 years. The contour mining method consists of removing overburden from

5832-857: The coal resource may cause burial and loss of topsoil, exposes parent material, and creates large infertile wastelands. Soil disturbance and associated compaction result in conditions conducive to erosion. Soil removal from the area to be surface-mined alters or destroys many natural soil characteristics, and reduces its biodiversity and productivity for agriculture. Soil structure may be disturbed by pulverization or aggregate breakdown. Top 10 hard and brown coal producers in 2012 were (in million metric tons): China 3,621, United States 922, India 629, Australia 432, Indonesia 410, Russia 351, South Africa 261, Germany 196, Poland 144, and Kazakhstan 122. Coal has been mined in every state of Australia, but mainly in Queensland, New South Wales and Victoria. It

5940-419: The decline of the mines, the area has undergone a period of significant change, ameliorated to some extent by a shift to high technology , with companies establishing themselves in the area, attracted by grants and a willing workforce. Many mines have now been reclaimed by the forest and the area is characterised by picturesque scenery punctuated by remnants of the industrial age and small towns. There remains

6048-429: The developed world. Modern coal mining in the US has an average 23 deaths per year due to mine accidents (2001–2020). However, in lesser developed countries and some developing countries, many miners continue to die annually, either through direct accidents in coal mines or through adverse health consequences from working under poor conditions. China , in particular, has the highest number of coal mining related deaths in

6156-512: The discontented to the side of Charles II . After the restoration Sir John Winter successfully reasserted his right to the Forest of Dean. However forest law was reestablished by Act of Parliament in 1668. In 1672 the King's ironworks were closed to reduce pressure on the forest from mining. The Speech House , between Coleford and Cinderford , was built in 1682 to host the Court of Mine Law and "Court of

6264-455: The disruptive activities of blasting, ripping, and excavating coal. Stripping of overburden eliminates and destroys archeological and historic features, unless they are removed beforehand. The removal of vegetative cover and activities associated with the construction of haul roads, stockpiling of topsoil, displacement of overburden and hauling of soil and coal increase the quantity of dust around mining operations. Dust degrades air quality in

6372-470: The earliest use of coal to Roman times for domestic heating and industrial processes such as the preparation of iron ore. The area gives its name to the local government district , Forest of Dean , and a parliamentary constituency , both of which cover wider areas than the historic Forest. The administrative centre of the local authority is Coleford , one of the main towns in the historic Forest area, together with Cinderford and Lydney . The origin of

6480-726: The early 19th century to facilitate freight traffic to and from mineral workings in the Forest. Many of these lines were part of the Severn & Wye Railway , which ran from the River Severn at Lydney to Cinderford, with branch lines to Lydbrook, where it connected with the Ross & Monmouth Railway , and Coleford, where it linked to the Wye Valley Railway via a line known as the Coleford Railway . The Forest of Dean Railway also ran towards Cinderford and its nearby collieries, branching from

6588-466: The enclosed areas and unable to hunt or remove timber. In particular, they lost their ancient grazing and mining rights. As unrest grew, a populist leader named Warren James emerged in the riots against the enclosures. Attempts to peaceably resolve the matter failed, and on 8 June 1831, James, leading more than 100 Foresters, demolished the enclosure at Park Hill, between Parkend and Bream . Around 50 unarmed Crown Officers were powerless to intervene. On

The central parts of the woodlands in the forest are believed to have been protected for hunting since Roman times. The area formed part of the Cantref Coch and was traditionally considered part of the Brythonic kingdom of Ergyng , centered in modern Herefordshire. Even when

6804-571: The fatalities occurring in the first half of the 20th century. 3,242 died in 1907, the worst year ever; in 2020 there were five. Open cut hazards are principally mine wall failures and vehicle collisions; underground mining hazards include suffocation, gas poisoning, roof collapse, rock burst , outbursts , and gas explosions. Firedamp explosions can trigger the far more dangerous coal dust explosions, which can engulf an entire mine. Most of these risks are greatly reduced in modern mines, and multiple fatality incidents are now rare in most parts of

6912-522: The forest. The mixed forest supports one of Britain's highest concentrations of goshawks and a viewing site at New Fancy is manned during February and March. However, goshawks are still illegally killed in the area, with a bird found dead with a shotgun wound in June 2022. Peregrine falcons can be seen from the viewpoint at Symonds Yat rock. Mandarin ducks , which nest in the trees, and reed warblers can be seen at Cannop Ponds and Cannop Brook, running from

7020-533: The fringes of the Crown forest demesne. By about 1800, these settlements were well established at Berry Hill and Parkend . In 1808 Parliament passed the Dean and New Forests Act 1808 , which included the provision to enclose 11,000 acres (4,500 ha) of woodland. This enclosure was carried out between 1814 and 1816. There were bread riots in 1795 and in 1801. Ordinary Foresters were already poverty-stricken, and their plight had grown worse. They were denied access to

7128-457: The genetic soil profile, displaces or destroys wildlife and habitat, alters current land uses, and to some extent permanently changes the general topography of the area mined. Adverse impacts on geological features of human interest may occur in a coal strip mine. Geomorphic and geophysical features and outstanding scenic resources may be sacrificed by indiscriminate mining. Paleontological, cultural, and other historic values may be endangered due to

7236-553: The historic Forest; they do not include places which are located outside that area, but which are within the larger District Council area. The A40 runs along the northern and northeastern edges of the Forest of Dean. The road provides the Forest with a direct connection to Ross-on-Wye and the M50 in Herefordshire . Westbound, the road runs towards Monmouth and South Wales . To the East,

7344-450: The immediate area, has an adverse impact on vegetative life, and constitutes health and safety hazards for mine workers and nearby residents. Surface mining disrupts virtually all aesthetic elements of the landscape. Alteration of land forms often imposes unfamiliar and discontinuous configurations. New linear patterns appear as material is extracted and waste piles are developed. Different colors and textures are exposed as vegetative cover

7452-684: The lands was voided by Parliament in March 1642, in part because he had failed to pay. His assets were sequestrated for supporting the Crown during the Civil War . The Protectorate tried to enclose a third of the forest in 1657, leaving two thirds to the Commoners. Although a relatively generous settlement, it caused resistance in April and May 1659, when fences of new enclosures were broken and cattle brought in to graze. Royalists including Edward Massey attempted to bring

7560-460: The late 18th century onward, with further progress being driven by 19th-century and early 20th-century progress. However, oil and gas were increasingly used as alternatives from the 1860s onward. By the late 20th century, coal was, for the most part, replaced in domestic as well as industrial and transportation usage by oil , natural gas or electricity produced from oil, gas, nuclear power or renewable energy sources. By 2010, coal produced over

7668-404: The majority of fatalities. Coal mining resulted in 47 fatalities that year. One study, though, has suggested that hazards of modern mining are now more accretive with workers facing long-term health impacts, such as sleep deprivation, that build up over time. Strip mining severely alters the landscape, which reduces the value of the natural environment in the surrounding land. The land surface

7776-473: The male working population worked in the coal industry but after the Second World War increased pumping costs and other factors made the coalfield less economic. The last commercial iron mine closed in 1946 followed in 1965 by the closure of the last large colliery, Northern United. There are still small private mines in operation, worked by freeminers and Hopewell Colliery is open to the public. With

7884-461: The method of extraction. For example, a study has found that among surface coal mine operations, dragline equipment produced the loudest sound at a range of 88–112 dBA. Within longwall sections, stageloaders used to transport coal from the mining face and shearers used for extraction represent some of the highest noise exposures. Auxiliary fans (up to 120 dBA), continuous mining machines (up to 109 dBA), and roof bolters (up to 103 dBA) represent some of

7992-465: The mid-1860s, Easter, a deep mine at Milkwall, employed around 50 men and boys. An early tramroad to serve the mines, was built by the Severn & Wye tramroad company to connect to their junction at Parkend . In 1875, the Severn & Wye constructed a railway to Coleford. It left the main line at Parkend and in places shadowed the Milkwall branch tramroad. A station was provided at Milkwall for this branch line. The production of lime , which during

8100-465: The mining workforce. in 2015 US coal mines had 65,971 employees, the lowest figure since EIA began collecting data in 1978. However, a 2016 study reported that a relatively minor investment would allow most coal workers to retrain for the solar energy industry. Coal mining has been a very dangerous activity and the list of historical coal mining disasters is long. In the U.S., 104,895 coal miners were killed in mine accidents since 1900, 90 percent of

8208-399: The name is unknown. The prevalence of Welsh place names in the area suggests a possible corruption of din (meaning "hillfort"). However, similar or identical elements from Old English exist throughout England. In Welsh, Forest of Dean is Fforest y Ddena . Gerald of Wales , writing in the 12th century, refers to the area as Danubia which may translate as "land of Danes" following

8316-469: The noisiest equipment within continuous mining sections. Exposures to noise exceeding 90 dBA can lead to adverse effects on workers' hearing. The use of administrative controls and engineering controls can be used to reduce noise exposures. Improvements in mining methods (e.g. longwall mining), hazardous gas monitoring (such as safety-lamps or more modern electronic gas monitors), gas drainage, electrical equipment , and ventilation have reduced many of

8424-482: The north, and Chepstow , Newport , Cardiff and onward destinations in South Wales . CrossCountry runs limited services to the station, linking the Forest to Birmingham New Street and onward destinations in the Midlands . In 1967, John Berger 's sociological work A Fortunate Man was set in the Forest of Dean. A film of the same name was filmed in the Forest of Dean in 1972. Coal mining Coal mining

8532-585: The open pit methods, due to thickness of the seam 20–25 metres (60–90 feet). Coals occurring below 90 m (300 ft) are usually deep mined. However, there are open pit mining operations working on coal seams up to 300–460 metres (1,000–1,500 feet) below ground level, for instance Tagebau Hambach in Germany. When coal seams are near the surface, it may be economical to extract the coal using open-cut , also referred to as open-cast, open-pit, mountaintop removal or strip, mining methods. Opencast coal mining recovers

8640-421: The operation reaches a predetermined stripping ratio (tons of overburden/tons of coal), it is not profitable to continue. Depending on the equipment available, it may not be technically feasible to exceed a certain height of highwall. At this point, it is possible to produce more coal with the augering method in which spiral drills bore tunnels into a highwall laterally from the bench to extract coal without removing

8748-408: The overburden. Mountaintop coal mining is a surface mining practice involving removal of mountaintops to expose coal seams, and disposing of associated mining overburden in adjacent "valley fills." Valley fills occur in steep terrain where there are limited disposal alternatives. Mountaintop removal mining combines area and contour strip mining methods. In areas with rolling or steep terrain with

8856-472: The paper and fibreboard industries and in drills. A beerhouse (later to become the Tufthorn inn) opened at Milkwall by the late-1870s. A wooden village hall was built after World War I and a recreation ground was laid out in the mid-1930s. An association football club had its own ground by the later 1950s. A social club built at Milkwall by 1959 was later enlarged. Forest of Dean The Forest of Dean

8964-538: The ponds through Parkend, is famed for its dippers . Butterflies of note are the small pearl-bordered fritillary , wood white and white admiral . Gorsty Knoll is famed for its glowworms and Woorgreens Lake for its dragonflies . The Forest of Dean is also a stronghold for Britain's only venomous snake, the European adder , although its population is now believed to be in dramatic decline. The lists below include towns, villages and places of interest which are within

9072-425: The potential to spontaneously ignite. Because most coal refuse harbors toxic components, it is not easily reclaimed by replanting with plants like beach grasses. The use of sophisticated sensing equipment to monitor air quality is common and has replaced the use of small animals such as canaries, often referred to as " miner's canaries ". In the United States, the increase in technology has significantly decreased

9180-402: The presence of coal was well known, and limited amounts had been recovered in Roman times. Coal was not used for ironmaking with the methods of smelting then in use. Later the freeminer rights were used mainly for coal mining. The activities of the miners were regulated by the Court of Mine Law. This, and other forms of self-governance, coupled with the Forest's geographic isolation between

9288-432: The production of iron, using charcoal, for hundreds of years. Despite the abundance of coal, it was not until the last decade of the 18th century that local ironmasters were prepared to invest in the technology needed to produce iron from coke , when coke-fired furnaces at Cinderford , Whitecliff and Parkend were built almost simultaneously. During the 18th century, squatters established roughly-built hamlets around

9396-400: The public. The Park Gutter pit was renamed Princess Royal after Princess Victoria in 1842. The Princess Royal Colliery Company was founded in 1891 to work Park Gutter and Flour Mill Pits. It reached peak production in the 1930s, employing 1300 men. The pits closed in 1962. Cinderford was laid out as a planned town in the mid-19th century, but the characteristic form of settlement remained

9504-399: The risks of rock falls, explosions, and unhealthy air quality. Gases released during the mining process can be recovered to generate electricity and improve worker safety with gas engines . Another innovation in recent years is the use of closed circuit escape respirators , respirators that contain oxygen for situations where mine ventilation is compromised. Statistical analyses performed by

9612-465: The rivers Severn and Wye, has given rise to a strong sense of cultural identity in those from the area, who are collectively known as "Foresters". The ancient rights were put on the statute books in the Dean Forest (Mines) Act 1838 , the only public act to affect private individuals. Residents of the hundred over 18 can graze sheep in the Forest in accordance with an agreement between Forestry England and

9720-677: The road links the Forest directly to Gloucester , the M5 , Cheltenham and Oxford . North of the Forest, the road is managed by National Highways . To the southeast of the Forest, the A48 links the region to Chepstow , the M4 and Newport , or Gloucester . This route passes around the Lydney area and follows the course of the River Severn . Other key routes include: Nitrogen Dioxide (NO 2 ) levels, measured using roadside diffusion tubes , are generally well below

9828-488: The royal demesne and parts of parishes within the hundred of St Briavels , and after 1668 comprised the royal demesne only. The Forest proper is within the civil parishes of West Dean , Lydbrook , Cinderford , Ruspidge , and Drybrook , together with a strip of land in the parish of English Bicknor . Traditionally the main sources of work have been forestry  – including charcoal production – iron working and coal mining . Archaeological studies have dated

9936-418: The seam for roof and floor conditions; topography, especially altitude and slope; climate; land ownership as it affects the availability of land for mining and access; surface drainage patterns; groundwater conditions; availability of labor and materials; coal purchaser requirements in terms of tonnage, quality, and destination; and capital investment requirements. Surface mining and deep underground mining are

10044-565: The seam in a pattern following the contours along a ridge or around the hillside. This method is most commonly used in areas with rolling to steep terrain. It was once common to deposit the spoil on the downslope side of the bench thus created, but this method of spoil disposal consumed much additional land and created severe landslide and erosion problems. To alleviate these problems, a variety of methods were devised to use freshly cut overburden to refill mined-out areas. These haul-back or lateral movement methods generally consist of an initial cut with

10152-477: The source of the illegal dumps were unsuccessful and boar can now be found in many parts of the Forest. Locally there are mixed feelings about the presence of boar. Problems have included ploughing up gardens and picnic areas, attacking dogs and panicking horses, road traffic accidents, and ripping open rubbish bags. The local authority undertook a public consultation and have recommended to the Verderers that control

10260-432: The spoil deposited downslope or at some other site and spoil from the second cut refilling the first. A ridge of undisturbed natural material 15 to 20 ft (5 to 6 m) wide is often intentionally left at the outer edge of the mined area. This barrier adds stability to the reclaimed slope by preventing spoil from slumping or sliding downhill. The limitations of contour strip mining are both economic and technical. When

10368-487: The sprawling hamlets of haphazardly placed cottages. Characteristics shared with other British coalfields, such as a devotion to sport, the central role of miners' clubs, and the formation of brass bands , created a distinct community identity. In the late 19th and early 20th centuries, the Forest was a complex industrial region with deep coal mines, iron mines, iron and tinplate works, foundries, quarries and stone-dressing works, wood distillation works producing chemicals,

10476-556: The strong contribution coal plays in global warming and environmental issues, which result in decreasing demand and in some geographies, peak coal . Compared to wood fuels , coal yields a higher amount of energy per unit mass, specific energy or massic energy, and can often be obtained in areas where wood is not readily available. Though it was used historically as a domestic fuel, coal is now used mostly in industry, especially in smelting and alloy production, as well as electricity generation . Large-scale coal mining developed during

10584-476: The surface or overburden, of the mining area. The overburden is then removed by draglines or by shovel and truck. Once the coal seam is exposed, it is drilled, fractured and thoroughly mined in strips. The coal is then loaded onto large trucks or conveyors for transport to either the coal preparation plant or directly to where it will be used. Most open cast mines in the United States extract bituminous coal . In Canada, Australia, and South Africa, open cast mining

10692-568: The surviving ancient woodlands in England. A large area was reserved for royal hunting before 1066, and remained as the second largest crown forest in England, after the New Forest . Although the name is used loosely to refer to the part of Gloucestershire between the Severn and Wye, the Forest of Dean proper has covered a much smaller area since the Middle Ages . In 1327, it was defined to cover only

10800-524: The two basic methods of mining. The choice of mining method depends primarily on depth, density, overburden, and thickness of the coal seam; seams relatively close to the surface, at depths less than approximately 55 m (180 ft), are usually surface mined. Coal that occurs at depths of 55 to 90 m (180 to 300 ft) are usually deep mined, but in some cases surface mining techniques can be used. For example, some western U.S. coal that occur at depths in excess of 60 m (200 ft) are mined by

10908-441: The world, with official statistics claiming that 6,027 deaths occurred in 2004. To compare, 28 deaths were reported in the U.S. in the same year. Coal production in China is twice that in the US, while the number of coal miners is around 50 times that of the US, making deaths in coal mines in China 4 times as common per worker (108 times as common per unit output) as in the US. Mine disasters have still occurred in recent years in

11016-562: Was annexed into the kingdom of England by Æthelstan in 926. Throughout the next few centuries Vikings conducted raids up the Severn, but by the 11th century, the kingdom of Wessex had established civil government. The core of the forest was used by the late Anglo-Saxon kings, and after 1066 the Normans , as their personal hunting ground. The area was kept stocked with deer and wild boar and became important for timber , charcoal , iron ore and limestone . The Hundred of St Briavels

11124-413: Was at least one dwelling at Milkwall, situated on the Forest boundary in 1628. The earliest houses at Milkwall were within the parish of Coleford with just a few houses on the extraparochial Crown land . There was some mining in the 17th century when a drift mine was being worked at Milkwall. Mining for iron ore was taking place in the 1820s when Edward Protheroe opened up ore mines near Milkwall. In

11232-406: Was established in the 12th century, at the same time as many Norman laws concerning the Forest of Dean were put in place. St Briavels Castle became the Forest's administrative and judicial centre. Verderers were appointed to act for the king and protect his royal rights, and local people were given some common rights . Flaxley Abbey was built and given rights and privileges. In 1296, miners from

11340-736: Was later commuted to transportation. He was sent to Van Diemen's Land ( Tasmania ) in October 1831, only to be pardoned five years later, although he never returned home. Conservatives were disliked in the Forest of Dean; on polling day in 1874, there was a riot in the market town of Cinderford in which the Conservative party headquarters and nearby houses were ransacked and damaged. On 26 April 1889, four Frenchmen and their two bears were making their way to Ruardean , having performed in Cinderford. They were attacked by an angry mob, enraged by claims that

11448-531: Was mined, and 375.1 million tonnes was exported. In 2013/14, coal provided about 69% of Australia's electricity production. In 2013, Australia was the world's fifth-largest coal producer, after China, the United States, India, and Indonesia. However, in terms of proportion of production exported, Australia is the world's second largest coal exporter, as it exports roughly 73% of its coal production. Indonesia exports about 87% of its coal production. A court in Australia has cited climate change in ruling against

11556-599: Was probably established on a small scale in Roman times. The area was governed from the Roman town of Ariconium at Weston under Penyard near Ross-on-Wye , and a road was built from there to a river crossing at Newnham on Severn and port at Lydney. The "Dean Road", still visible at Soudley , is believed to be a medieval rebuilding of the Roman road , and would have been an important route to transport iron ore and finished metal products. During Roman times there were Roman villas at Blakeney, Woolaston and elsewhere, and towards

11664-538: Was used exclusively as a royal hunting ground for the Tudors , and subsequently a source of food for the royal court. Its rich deposits of iron ore led to its becoming a major source of iron. The forest's timber was particularly fine, and was regarded as the best material for building ships. In the 17th century, as a result of King Charles I 's decision to rule without Parliament , he sought to raise finances through grants of royal forest lands. 3,000 acres (1,200 ha) of
