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 called a 'pit ...

Mining in Wisconsin. Local governments have primary responsibility for regulating nonmetallic mines, but the DNR provides oversight for local reclamation programs and ensures that quarries, gravel pits and other operations meet state reclamation requirements. Nonmetallic mining operations must also get DNR water permits, and some need air permits.
These pressure anomaly data and the failures of rock associated with these anomalies are suggestive that shield-leg pressures and/or pillar pressure may be used as an indicator of impending ground hazards in underground coal mines, especially in the critical areas close to the face. Data for the minor face spalling events, the first major roof cave and floor heave failures discussed above indicate
In the Great Lakes region, coal ash polluted groundwater at 73 of 80 monitored sites.
