Simulation study on influencing factors of coal wall sudden extrusion in heading face

A three-dimensional numerical model of heading face was established based on Guoerzhuang Coal Mine in Handan, Hebei Province. The effects of different coal seam depths, driving speed and coal mechanical strength on the coal wall sudden extrusion are analyzed by using 3DEC discrete element simulation...
