摘要
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 mining hydrogeological data of Yaoqiao coalmine demonstrated that the direct mine water filling aquifers are Shanxi Formation roof and floor sandstone fissured aquifer and Taiyuan Formation limestone karstic fissured aquifer and generally from the aquifers＂ static reserve and they have weak water yield property. The Quaternary loose bed aquifers, Lower Shihezi Formation basal sandstone aquifer, Ordovician limestone karstic fissured aquifer and gob water infilling paths are all through water conducted zones. So pertinent mine flooding controlling measures of safety coal pillars, water conducted zone and gob water detection and drainage were advised.
