Abstract:

Based on broken rock layers, thinner waterproof layers, argillation, poorer bearing capacity and special replenishment of linear water channel near the water inrush point of F22-1 fault in Xindeng Coal Mine. From the aspects of strengthening the surrounding rock and flow of the water pressure and flow of the water channel, The techniques of roadway filling, surrounding rock reinforcement, hydrophobic depressurization, returned grouting, water diversion grouting are adopted to solve the problems of water channel collapse and change, poor waterproof layers, rock fracture. The purpose of water blocking in fault fracture zone has been successfully realized.
