Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef, or placer deposit.These deposits form a mineralized commodity that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay.Coal mining in the United States - Wikipedia,Coal mining in the United States is an industry in transition. Production in 2017 was down 33% from the peak production of 1,162.7 million short tons in 2006. Employment of 50,000 coal miners is down from a peak of 883,000 in 1923.

Coal mining requires a pollution control ('environment protection') licence under the Protection of the Environment Operations Act 1997 (NSW) if it exceeds the following thresholds set out in Schedule 1 of the Act: if it is mining, processing or handling of coal (including tailings and chitter) at underground mines or open cut mines and (a) it has a capacity to produce more than 500 tonnes of coal per day, or (b) itEnergy accidents - Wikipedia,Coal mining is the most dangerous occupation in China, the death rate for every 100 tons of coal mined is 100 times that of the death rate in the US and 30 times that achieved in South Africa. Moreover, 600,000 Chinese coal miners, as of 2004, were suffering from Coalworker's pneumoconiosis (known as "black lung") a disease of the lungs caused by long-continued inhalation of coal dust.Coalworker's pneumoconiosis - Wikipedia,Coal workers' pneumoconiosis, severe state, develops after the initial, milder form of the disease known as anthracosis. This is often asymptomatic and is found to at least some extent in all urban dwellers due to air pollution. Prolonged exposure to large amounts of coal dust can result in more serious forms of the disease, simple coal workers' pneumoconiosis and complicated coal workers' pneumoconiosis. More commonly, workers exposed to coal
The Sago Mine disaster was a coal mine explosion on January 2, 2006, at the Sago Mine in Sago, West Virginia, United States, near the Upshur County seat of Buckhannon.
