Environmental Risks in the Operation and Closure of Coal Mines
Abstract: The technical risks associated with the operation and closure of coal mines include the adverse environmental impact caused by: atmospheric pollution by greenhouse gas methane and combustion products of rock dumps, contamination of surface and underground water sources by highly mineralized mine waters, the risk of destruction of buildings, structures and communications when placed above the territories of worked-out mine fields. The use of methods for degassing coal seams and the application of microbiological destruction of methane using bacteria have been proved. To reduce the adverse impact of waste heaps, the construction of flat dumps and the use of «clay» screens have been proved. The characteristics of the impact of sub-projects on the state of the earth’s surface have been given, which cause the danger of destruction of buildings, structures and underground communications.
Keywords: coal mines, impact, methane, degassing, waste tanks, worked-out mine fields.
