姚桥煤矿开采水文地质资料表明,煤层开采矿井的直接充水含水层——山西组煤层顶、底板砂岩裂隙含水层组与太原组灰岩岩溶裂隙含水层一般以静储量为主,富水性较弱;第四系松散含水层组、下石盒子组底部分界砂岩含水层、奥陶系灰岩岩溶裂隙含水层、老窑水主要是通过断裂或导水裂隙向矿井充水,故而提出了留设保安煤柱,探放断层水、老窑水等针对性的水害防治措施。
The hydrogeological data of Yaoqiao Coal Mine show that the direct water-filled aquifer in the coal seam mining-the coal seam top and bottom sandstone fissure aquifer in Shanxi Formation and the limestone karst fissure aquifer in Taiyuan Formation are generally mainly static reserves, Weak; Quaternary loose aquifer group, the bottom of the Lower Shihezi Formation sandstone aquifer, Ordovician limestone karst fissure aquifer, the old kiln water is mainly through the fracture or water fissure to the mine water, it was proposed to stay The security pillar, exploration and discharge of fault water, old kiln water and other targeted water control measures.
