【摘要】：以貴州某巖溶發(fā)育礦區(qū)為研究背景,通過對煤礦水文地質(zhì)條件和礦井充水因素進(jìn)行分析,并應(yīng)用高密度電法對礦井水文地質(zhì)進(jìn)行了勘查,得出礦區(qū)水文條件屬于巖溶裂隙充水礦床,頂、底板直接進(jìn)水。煤層開采后導(dǎo)水裂隙帶發(fā)育至吳家坪組第2段,并與該段含水層連通起來,對上覆含水層形成卸壓作用,該含水層含水量較小補給能力差,頂板突水可能性小。
[Abstract]:Taking a karst mining area in Guizhou as the research background, the hydrogeological conditions of coal mine and the factors of mine water filling are analyzed, and the high density electric method is applied to the exploration of mine hydrogeology. It is concluded that the hydrological conditions of the mining area belong to the karst fissure water filling deposit. The fracture zone of water conduction developed to the second member of Wujiaping formation after coal seam mining, and connected with the aquifer, which formed a pressure relief effect on the overlying aquifer. The water content of the aquifer was lower than that of the overlying aquifer, and the possibility of water inrush from the roof was small.
