以贵州某岩溶发育矿区为研究背景,通过对煤矿水文地质条件和矿井充水因素进行分析,并应用高密度电法对矿井水文地质进行了勘查,得出矿区水文条件属于岩溶裂隙充水矿床,顶、底板直接进水。煤层开采后导水裂隙带发育至吴家坪组第2段,并与该段含水层连通起来,对上覆含水层形成卸压作用,该含水层含水量较小补给能力差,顶板突水可能性小。
Taking a karst development mining area in Guizhou as the research background, by analyzing the hydrogeological conditions and mine water filling factors in coal mines, the hydrogeology of the mine is explored by using the high-density electrical method. It is concluded that the hydrological conditions in the mining area belong to karst fissure- Top, floor directly into the water. The water-bearing fracture zone developed to the second stage of Wujiaping Formation after the coal seam mining, and connected with the aquifer in this section, forming a pressure relief action on the overlying aquifer. The water supply capacity of the aquifer is small, and the possibility of roof water inrush small.
