During the initial excavation process of the north connection rail line roadway at -1000 m level of Qishan Mine,a certain large roof falling zone occurred in the roof of the mine roadway with a fault.With the analysis on the engineering geological conditions of the mine roadway and the research on the surrounding rock features, the type of the roadway surrounding rock and the deformation mechanics mechanism were set up.The paper provided the repair and support technology of the mien roadway and the site application of the technology obtained the successful results.
