Coal Mining Effects on the Environment

Coal mining increases the risk of loosening top soils into streams and waterways and the sediments pollute our water and can smother plant life downstream and even kill fish. Coal has traces of sulfur and nitrogen. When burned, these are released into the atmosphere. While these chemicals are floating in the air, they can mix with water vapor ...

Influence of anti-pyrogenic materials on coal mining

2016-1-1  Because of the fact that coal presence is a fundamental factor which influences the self-ignition of mining waste, attempts are often made to use methods and procedures that analyse bituminous coal's tendency to self-ignite (Cygankiewicz, 1999). Such attempts were described in statutory and commercial work of the Central Mining Institute (GIG).
