| 摘 要： | 通过综合分析葛泉矿东井9#煤采区的地质、水文地质条件,利用综合勘探技术对煤层底板进行异常区域探测,并对异常区进行注浆封堵,同时注浆改造煤层底板岩层,从而切断了煤层底板下伏奥灰含水层与上覆含水层之间的水力联系,有效降低了奥灰水对矿井生产的威胁,实现了下组煤的安全开采.总结出一套以煤层底板注浆改造为主体的综合防治水技术,对本区乃至全国类似条件下下组煤开采具有重要的指导意义.

| Abstract: | Based on the comprehensive analysis of geology and hydrogeology conditions about 9# coal in Dongjing of Gequan coal mine, the abnormal regions were detected and grouted by use of integrated exploration technique. The hydraulic connection among aquifer in Ordovician limestone and Daqing limestone were cut off by grouting reconstruction and fracture sealing for coal floor. The lower coal seam suffered from Ordovician limestone water invasion was mined safely. The technology for prevention of mine water was su... |
