常兴煤矿矿井水综合防治技术分析
|
摘要
本文将常兴煤矿防治水作为研究对象,分析了常兴煤矿主要的矿井水来源有大气降水和地表水、煤层顶板含水层水、采空区(小窑)积水、奥陶系中统灰岩岩溶裂隙含水层等,并结合常兴煤矿实际,从排水能力设计等方面提出了对应的综合防治技术对策,从常兴煤矿现场应用情况来看,取得了较好的防治效果。
This paper takes Changxing coal mine control water as the research object, and analyzes the main source of mine water in Changxing coal mine, including atmospheric precipitation and surface water, coal seam roof aquifer water, mined area(small kiln) water accumulation,Ordovician limestone karst fissure aquifers and so on, and combined with the practice of Changxing coal mine, from the design of drainage capacity and so on. The corresponding countermeasures for comprehensive prevention and control are put forward. From the field application of Changxing coal mine, good control results are obtained.
