五轮山井田初期采区矿井充水因素分析

通过对五轮山井田水文地质条件、地表水及地下水动态特征及井巷开拓过程中反映的水文地质资料的研究与分析,认为正常情况下,五轮山井田各含水层对煤层开采不构成直接威胁,浅部煤层开采时局部与第四系孔隙水会有直接的水力联系,矿井田初期开采防范的重点是老窑积水和断层导水,其造成的灾害可能是毁灭性的。

Mine Water Filling Factor Analysis of the Initial Mining Area in Wulunshan Minefield

After studied and analyzed hydrogeological conditions,surface water and ground water dynamic characteristics,hy-drogeological data obtained during mine workings opening-up,considered that under the normal condition,particular aquifer in Wulunshan minefield unlikely has threat to coal mining.But during the shallow coal seam mining,the Quaternary pore water has local direct hydraulic connection,and the focal point of to keep away is gob water and fault conducted water,because of calamities bring about may be destructive.
