Abstract In order to solve the mining effect of the mining roadway in the working face of Liyazhuang Mine during mining, the deformation of the roadway near the fault was serious, which seriously affected the normal mining operation. The theoretical support, field observation and calculation were used to optimize the support system of the roadway. Through the application practice and on-site observation, it has proved that the support effect was better, and it provided a reference for the production design of the working face under similar geological conditions.
