摘要
以山西大同同忻煤矿为实例,结合含水层岩性组合特征,将地下含水层划分为变质岩裂隙含水层、岩浆岩裂隙含水层、碳酸盐岩岩溶裂隙含水层、碎屑岩裂隙含水层和松散岩孔隙含水层,并推断出矿采空区积水充水强度和主采煤层正常块段突水系数,为该矿的防治水措施提供技术数据支持。
Shanxi Datong Tongxin Mine was taken as the example, combined with aquifer lithology combination feature, underground aquifer was divided into metamorphic rock fissure aquifer, magmatic rocks fissure aquifer, carbonate rock karst fissure aquifer, clastic rock fissure aquifer and loose rock aquifer, the intensity of water filling in goaf and water bursting coefficient in normal section of mining coal seam provided data support for the mine water prevention and control.
