河南瑞平煤电(集团)庇山矿充水因素分析

Water Filling Factor Analysis of Bishan Coalmine,Ruiping Coal and Power Group,Henan

通过对河南省汝州市庇山煤矿区的水文地质条件分析,认为矿井主要充水水源为上部老窑积水、第四系孔隙水、砂岩裂隙水及灰岩岩溶裂隙水。除第四系松散孔隙含水层富水性较强外,其它各含水层富水性均较弱,对井下煤层开采威胁不大,老窑积水是构成上部煤层开采充水的主要因素,充水通道为采空塌陷带及构造断裂带。建议开展水文地质物探工作,为矿井防治水提供参考依据。

Through analysis of hydrogeological conditions in Bishan coalmine of Ruzhou City, Henan Province showing that the main water filling sources have upper part gob water, Quaternary pore water, sandstone fissure water and limestone karstic fissure water. Except the Quaternary is a loose bed strong pore aquifer, the rest are all weak water yield property aquifers, and less threatening to underground coal mining. Gob water is a main water filling factor of upper coal seams mining. Water filling channels are gob subsidence and fault zones. It is advised that to carry out hydrogeology geophysical prospecting to provide referential mine water control basis.
