Abstract: In view of the great mining height of the Shihe mine, the mining pressure at the end of the mining stage appeared severely, easily leading to the occurrence of the film gang, the top of the situation, affecting the smooth withdrawal of the hydraulic support further. Using new inorganic grouting material to advance pre-reinforcement of coal body within 40 meters from the main draw-off passage. In addition,a small amount of organic grouting material was refilled in local areas of the mining side of the withdrawal channel. The application of the joint grouting reinforcement technology effectively solved the problems such as chipping and leaking at the final mining stage of large mining face, and realized the safe and rapid penetration of the working face and the main pull-out channel. By comparing the final mining time and the grouting cost at the end, the joint grouting reinforcement achieved better efficiency and benefit than simply using organic material grouting reinforcement.
