Numerical simulation of underground pressure in super-length working face
Stress distribution surrounding the normal (160m) and super-length (400) working face were simulated with FLAC software.Underground pressure regularity of normal and super-length were contrasted and analyzed.The simulation results show that the first falling pace,first pressure pace and periodic pressure pace of super-length working face are less than that of the normal working face;the abutment pressure distributions of two length working face have the similar regularity.
