Main technical content: This document specifies the terms and definitions of the grouting treatment technology for fault fracture zones, the exploration of fault fracture zones, the treatment of fault fracture zones, grouting materials and equipment, treatment processes, safety and precautions, and quality inspection and acceptance. This document is applicable to the treatment of fault fracture zones. It adopts grouting reinforcement measures for the working face floor, reinforces the fault fracture zones, and achieves efficient, green, and safe mining of the working face. The inspection results are good. The cement slurry and the fracture zones are integrated, and the fractured sections are well reinforced. It plays a good demonstration role in the future grouting reinforcement of fracture zones, eliminates the occurrence of roof safety accidents and hidden dangers, and improves production efficiency.
