崔家沟煤矿矿井充水因素分析

摘要

崔家沟煤矿矿井涌水量呈逐年增大趋势,并于2008年1月17日在2107工作面发生了突水事故,给煤矿的安全生产带来了严重威胁.研究矿井水文地质条件、分析矿井充水因素具有重要的现实意义.根据崔家沟煤矿地质勘探和生产揭露的水文地质观测资料以及煤层开采导水裂隙带高度计算结果的综合分析,认为矿井直接充水水源主要是洛河组砂岩裂隙水和老空区积水,大气降水和地表水为其间接充水水源；主要的充水通道为采动导水裂隙带,其次是断裂构造.%The amount of gushing water in Cuijiagou coal mine increases year by year, and on January 17, 2008 occurred water inrush accident in 1207 work face brings serious threat to safety production of coal mine. The study and analysis of mine hydrogeologic conditions and water filling factors has important practical significance. According to Cuijiagou coal mine geological exploration and hydrogeological observation information and integrated analysis seam mining-caused water fracture height calculation results , proved that the main reason of mine directly filled water is Luo He sandstone aquifer water and older goaf water, atmospheric precipitation and surface water for its indirect water filling source; the main of filled water channel is mining-caused fractured zone, followed is fracture structure.
