摘要
肥城矿区水文地质条件极其复杂,奥灰水水位高,水量大,严重制约着煤矿开采的正常进行。通过肥城矿区井下施工奥灰孔进行奥灰水治理的经验及技术,认为井下施工奥灰孔,建立井下水文观测网以及对奥灰表层进行注浆改造,是行之有效的防治奥灰水的途径。
In Feicheng Mi ni ng Area,there are very complex hydrogeological conditions,and high water level and large quantity of water,of Karst water of Ordovician limestone.It restric t seriously normal progress of coal mining.Through harness experience and techn ology for Karst water in Ordovician limestone with construction of underground h ole in Feicheng Mining Area,hold that construction of underground Ordovician li mestone,establishment of underground hydrologic observation net,and grouting transform for surface of Ordovician limestone,are effective way to prevention a nd cure Karst water in Ordovician limestone.
