RESEARCH ON THE ROCK BURST MECHANISM OF THE OVERALL REMOVAL OF COAL TUNNEL WALL IN DATONG COAL MINING AREAS THREE HARD COAL ROADWAY
By establishing the mathematical and mechanics model the coal tunnel wall can be pushed out overall into three hard coal roadways of Datong Coal Mining Area, this paper studies the mechanism of this type of rock burst. Under the condition of the separation of the seam and the roof, it is possible to have the coal wall vulnerably squeezed out and moved outward as a whole. This is because the vertical stress and the occurrence of coal as a whole is moved with very small demands.
