Coal mining - Wikipedia

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 alternativesMining in Europe | Euromines,The European mining industry is fundamental for the continent's economic well-being Consumption of aggregates, industrial minerals and metals in Europe has grown rapidly over the past decade Today, Europe is almost self-sufficient in producing many industrial minerals and aggregates However, it is a significant net-importer of most metals and metal oresHistory of coal mining - Wikipedia,The history of coal mining goes back thousands of years 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 electricityCoal Mining Methods - EMFI,Other underground coal mines are laid out in a checkerboard of rooms and pillars (Fig 2), and the mining operation involves cyclical, step by-step mining sequences The rooms are the empty areas from which coal has been mined, and the pillars are blocks of coal (generally 40Europe’s last coal mines struggle for lifelines – POLITICO,In Poland, where coal produces almost 90 percent of electricity, the government hopes to create a new coal company, Polska Grupa Górnicza, to take over the productive assets of Europe's largest coal miner, the ailing Kompania Węglowa Last year it posted a loss of 1 billion złoty (€233 million) JSW, a hard coal miner, had a 31 billion złoty loss in 2015 The Polish government is in negotiations with theGermany | the voice of coal in Europe,Germany has considerable reserves of hard coal and lignite, making these the country’s most important indigenous sources of energy However, in the case of hard coal, there remain only approximately 20 million tonnes to be extracted following the political decision to end subsidised German hard coal production in 2018Coal mining | World Coal Association,In room-and-pillar mining, coal deposits are mined by cutting a network of 'rooms' into the coal seam and leaving behind 'pillars' of coal to support the roof of the mine These pillars can be up to 40% of the total coal in the seam - although this coal can sometimes be recovered at a later stageEuropean Coal Map,The interactive Coal Map of Europe gives an overview of the role of coal in our electricity system It maps different aspects of the coal business, ranging from where the coal plants are located to the health and climate impacts, government involvement and growing resistance from citizensManagement of Tailings and Waste-Rock in Mining Activities,Management of tailings and waste-rock in mining iii Some parts of the mining industry, such as metal and coal mining within Europe, operate under severe economic conditions, mainly because the deposits can no longer compete on anCHAPTER 11 Mining Technology - Princeton University,CHAPTER 11 Mining Technology \ face mining methods The thick coal seams in the Powder River basin are considered at- tractive in their potential for in situ gasifica-tion, and two separate small-scale test sites have been developed in Campbell County, Wyo, one by the Department of Energy (Hoe Creek Site) and another by ARCO Coal Co In situ gasification in this country is still in
