Abstract

The paper is devoted to safety issues during underground coal mining, it analyzes the current state and identifies prospects for increasing the volume of annual global coal production by underground mining method. An analysis of the rock bursts that occurred in the coal mines of the People’s Republic of China was performed and an annual increase in their numbers during the mining of coal seams at shallow depth up to 400 m was noted. Solving the problem of sudden rock pressure release in a dynamic form the nature of occurrence and the mechanism of geodynamic phenomena development including the energy parameters of trigger geodynamic processes in strata rocks have been described and determined. Dependency of the destruction energy level of the conveyor drift on the distance to the working face along the length of the destroyed mine working is investigated and described.

Keywords

Coal mining, underground mine, safety, rock pressure, stress distribution, destruction, rockburst, strata control, monitoring.
