United grouting reinforcement at up and down mine in water-conducting channels of medium-sized faults
Abstract：The coal mine water hazard controlling technique of united grouting reinforcement at up and down mine in water-conducting channels of medium-sized faults was put forward with analysis of geological structure water filling sources and characteristic of flood damage of faults in Jiaozuo Mining Area.The technique was carried out field application in Yanmazhuang Mine and Jiulishan Mine.It indicates that the technique has important significance to weaken water-bearing capacity of aquifers and cutting-off recharge path of fault and strengthen the intensity of roadway surrounding rock and water-resisting floor,and make roadway avoid water bursting diving.
