摘　　要：煤矿水害是矿山建设与生产过程中主要的灾害之一,有效的疏水方案对煤矿安全生产至关重要。通过分析洪崖煤矿的地质及水文地质资料,9号煤层主要充水水源为太原组各灰岩含水层,以K_(2)、K_(3)、K_(4)灰岩为主,主要的水害类型为顶板灰岩水害,充水通道主要为顶板导水裂缝带。太原组灰岩水对9号煤层的开采威胁程度较大,根据水害类型及其威胁程度,制定了针对性的防治水技术设计方案:主要包括巷道掘进顶板灰岩水害的防治方案、工作面回采顶板灰岩水害的防治方案、9号煤层同层老空区水害的防治方案和断层水害的防治方案;并验证了巷道掘进顶板灰岩水害的防治方案、工作面回采顶板灰岩水害的防治方案。统计近三年的矿井涌水量及涌水量构成,表明上述方案的矿井水害防治效果良好。Coal mine water disaster is one of the main disasters in mine construction and production,and an effective hydrophobic scheme is crucial to the safety production of coal mines.By analyzing the geological and hydrogeological data of Hongya Colliery,the author determines that the main water source for filling the No.9 coal seam is the various limestone aquifers of the Taiyuan Formation,mainly K2,K3,and K4 limestone.The main type of water disaster is roof limestone water disaster,and the water filling channel is mainly the roof water conducting crack zone.Based on the types of water disaster and its degree of threat,the author also develops water disaster prevention technology design plans for No.9 coal seam:mainly including the prevention plan for limestone water disaster in the roadway excavation roof,the prevention plan for limestone water disaster in the working face mining roof,the prevention plan for water disaster in the same layer of old goaf and fault in No.9 coal seam,and verifies the first two plans.The water inflow and its composition in the mine over the past three years indicate that the above-mentioned plans have a good effect on preventing and controlling mine water disasters.
