In order to make the 21105 working face of Zhengwang Coal Mine pass through the D2 fault smoothly under the premise of ensuring safe mining, through the analysis of the geological and surrounding rock conditions of the working face, the fault layer is designed near the fault, and the roadway is pre-excavated in the design layer. The roof pressure is used to make the rock pillar in the designed fault layer reach the plastic state, reduce the strength of the rock stratum, and then use the shearer to cut the rock pillar directly through the D2 fault. The practice shows that the scheme effectively shortens the construction period and ensures the safe production of the mine. It shows that the scheme is feasible in technology and provides technical experience for the subsequent mining face to cross the fault.
