In the face of large faults, the working face needs to jump mining to ensure the mining efficiency. The roadway in the jump mining area is affected by the roof pressure, which is easy to produce roof fall, rib spalling and other failure forms. In order to solve the problem of roadway support in the jump mining section of No.W3233 Face in Qianyingzi Mine, combined with the field engineering conditions, through the theoretical analysis of the roof pressure situation, combined with similar engineering experience, a reasonable pre-splitting blasting roof cutting scheme was proposed for the coal exploration roadway in the jump mining area and the W3233 air roadway retaining part, and a set of reasonable blasting parameters were studied and analyzed. At the same time, the roadway was strengthened and supported. Through theoretical analysis and FLAC3D finite element analysis software simulation, the prestress field generated by the bolt-cable system under the design support scheme was analyzed. The results showed that a continuous effective high stress zone could be formed near the roadway, which played a reinforcing role in the surrounding rock mass. Combined with the pre-splitting blasting roof cutting scheme, the ideal support effect was achieved.
