摘　　要：通过对焦作矿区地质构造、充水水源和断层充水水害特征的分析,提出了中型断层导水通道井上下联合注浆加固的矿井水害防治技术,并实际应用于九里山矿和演马庄矿中型断层导水通道的防治水工作中.研究表明,井上下联合注浆加固技术对于减弱含水层的富水性并切断断层补给通道,增强巷道围岩及底板隔水层的强度,实现巷道不突水掘进,均具有十分重要的意义.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.
