The Somerset Coalfield covers a total area of about 240 square miles (622 km 2). [1] It consists of three synclines, informally referred to as 'coal basins'.The Pensford Syncline in the north and the Radstock Syncline in the south are separated by the east–west trending Farmborough Fault Belt. [2]
Coal waste in Pennsylvania. Coal refuse (also described as coal waste, rock, slag, coal tailings, waste material, rock bank, culm, boney, or gob [1]) is the material left over from coal mining, usually as tailings piles or spoil tips.
The bottom of the furnace also fills with molten slag, often consisting of fayalite, a compound of silicon, oxygen and iron mixed with other impurities from the ore. Because the bloom is highly porous, and its open spaces are full of slag, the bloom must later be reheated and beaten with a hammer to drive the molten slag out of it.
This is a list of Superfund sites in Missouri designated under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) environmental law. The CERCLA federal law of 1980 authorized the United States Environmental Protection Agency (EPA) to create a list of polluted locations requiring a long-term response to clean up hazardous material contaminations.

By 1899, the mine worked three shifts and produced 36,287 tonnes (35,714 long tons; 40,000 short tons) annually. [3] A steam hoist hauled the cars up the slag heap for dumping the waste. [8] In 1901, 16 miners died in a fire beneath ground. The fire still burning over four months later, the mine was flooded to extinguish the flames.
The local mine's spoil tip, which he calls a slag heap, is the central figure of devastation. Eventually the pile overtakes the entire valley and crushes Huw Morgan's house: The slagheap is moving again. I can hear it whispering to itself, and as it whispers, the walls of this brave little house are girding themselves to withstand the assault.
The largest mine in the range, Soudan, was closed in 1962, and the last mine in the Ely area closed in 1964. [ 2 ] Despite the effort needed for the deep mining Soudan mine, the ore obtained was worth the effort; the quality of the hematite ore was so pure that two pieces could be welded. [ 1 ]
The South Walker Creek Coal Mine is an Open Cut coal mine in Strathfield, Isaac Region, Central Queensland region of Australia. The mine has coal reserves amounting to 298 million tonnes of coking coal, one of the largest coal reserves in Asia and the world. As at 2012, the mine had an annual production capacity of 3.6 million tonnes of coal. [1]
