| 摘 要： | 分析了关石焦煤矿水文地质特征,矿区内共有5个含水层和2个隔水层。确定了二叠系上统龙潭组煤层底板茅口组岩溶裂隙水为主要充水水源,构造裂隙及采动裂隙为主要充水通道,尤其在二叠系的下段容易发生突水,水文地质条件比较复杂。采用比拟法和大井法对新矿井的涌水量进行了预测,预测出新矿井的正常涌水量和最大涌水量分别为795,999 m^3/d,为矿井水害防治和安全生产提供了科学依据。

| Abstract: | This paper analysed the hydrogeological characters of Guanshijiao Coal Mine,there are five permeable layers and two impermeable layers in coal mine.Based on the analysis,the paper proposed that the permeable layer of upper permian Longtan formation coal seam floor,and karstic fissure water of Maokou formation are main source of water.The main underground watercourse are structural fissure and mining-induced fractures.The paper pointed out that it is easy to induce water outburst in lower part of permian,and... |
