Classification of roadway surrounding rock and application of bolt-mesh-cable support technology in Jinrui Coal Mine
CHEN Qing-feng
Abstract：Aiming at the surrounding rock conditions of No?8 roof and floor in Jinrui Coal Mine, field investigation and laboratory test were carried out to test the physical and mechanical parameters of roadway surrounding rock, the stability of surrounding rock was analyzed with FLAC3D numerical simulation, and roadway roof stability of Jinrui Coal Mine was graded based on the loose ring theory. Finally, bolt support scheme was chosen for the mine roadway, combining with safety and economy of the roadway.
