The Indonesian coal industry is rather fragmented with only a few big producers and many small players that own coal mines and coal mine concessions mainly in Sumatra and Kalimantan. Since the early 1990s, when the coal mining sector was reopened for foreign investment, Indonesia witnessed a robust increase in coal production, coal exports
Coal Mining in South Africa . Coal mining in South Africa plays a significant role in the countrys economy. Over 90 of the coal consumed in Africa is produced in South Africa. Coal mining in South Africa is centred on the Highveld, with roughly 60 of the countrys deposits located in eMalahleni Witbank and surrounding areas.
Coal mining is the process of extracting coal from the ground. 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 a 39pit39, and
Other underground coal mines are laid out in a checkerboard of rooms and pillars Fig. 2, and the mining operation involves cyclical, step bystep mining sequences. The rooms are the empty areas from which coal has been mined, and the pillars are blocks of coal generally 40 to 80 feet on a side left to support the mine roof.
Mining is the first step in the dirty life cycle of coal. When coal mines move in, whole communities are forced off their land by expanding mines, coal fires, subsidence, and overused and contaminated water supplies. Mines are quick to dig up and destroy forests and soils. But once the coal is gone, the problems they leave behind, like acid mine drainage, can persist for decades.
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 electricity. Coal mining continues as an important economic activity today. Compared to wood fuels, coal yields a higher amount of energy per mass and can often be obtained in
The largest coal mine in the world by reserves is the North Antelope Rochelle coal mine in the Powder River Basin of Wyoming, US. The mine was estimated to contain more than 1.7 billion tonnes of recoverable coal as of December 2018. Owned and operated by Peabody Energy, North Antelope is a surface mining operation with the sedimentary coal

During mining operations, enormous amounts of groundwater are drained from aquifers so mining companies can access coal seams up to 10,000 litres per tonne of coal. A series of proposed mines in Australias Galilee Basin is projected to extract 1,343 gigalitres of water over 212 times the amount of water in the Sydney Harbor.

Most of the coal mines may have closed in Appalachia, but that hasnt stopped the drive for coal. Perhaps in desperation more than greed, many people have turned to work with coal companies that use mountaintop removal mining, a procedure that levels entire tops of mountains and exposes the coal for collection. Its quick and dirty, and it
EPA promulgated the Coal Mining Effluent Guidelines and Standards 40 CFR Part 434 in 1975, and amended the regulation in 1976, 1977, 1979, 1982, 1985 and regulation covers wastewater discharges from mine drainage, coal storage facilities, and coal preparation plants.

Coal mining is only a temporary use of land, so it is vital that rehabilitation of land takes place once mining operations have stopped. In best practice a detailed rehabilitation or reclamation plan is designed and approved for each coal mine, covering the period from the start of operations until well after mining has finished.
