Abstract: In view of the serious deformation and failure of surrounding rock of high stress mining roadway near fault in the Shandong Xuchang Coal Mine, the support scheme and instability characteristics of the original mining roadway were analyzed by combining field measurement and numerical simulation. The asymmetric stability law of the mining roadway under the multiple superposition of fault structure, lateral abutment pressure of adjacent goaf and advanced abutment pressure of working face was studied. In this paper, according to the actual conditions of the 3318 working face belt transportation roadway in Xuchang Coal Mine, a new bolt-mesh support scheme with high strength, high stiffness and asymmetric characteristics is proposed. In this scheme, the 3318 working face belt transportation roadway is divided into two supporting sections A and B for layout. Through the field test, it is concluded that the deformation of surrounding rock of the 3318 working face belt conveyor roadway is reduced by more than 70 % after adopting the high strength and high stiffness asymmetric new anchor net support scheme. The relative displacement of roof and floor is reduced from 500 mm to 120 mm, and the relative displacement of two sides is reduced from 800 mm to 110 mm.
