摘要
山西省柳林县地方煤矿众多,各生产煤矿受"太灰"、"奥灰"岩溶水的威胁十分严重,但对整个矿区内含水层的水文地质特征认识程度较低。在山西省柳林县兼并重组整合煤矿区水文地质补充勘探项目基础上,通过研究柳林矿区内各含水层的地下水化学特征,进一步提升该区对煤矿开采有影响的含水层地下水赋存规律的认识程度,确定了柳林矿区主要含水层的特征离子,为今后矿井突水水源的研究判别提供依据;同时通过水化学同位素特征揭示了矿区内奥陶系含水层的补给、径流、排泄条件,即矿区地下水补给来源为大气降水,矿区位于柳林泉域岩溶地下水的集中排泄区下游,区内岩溶地下水径流滞缓、水循环条件差。
There are many local coalmines in the Liulin County, Shanxi Province. Coalmines are seriously threatened by karst water from Taiyuan Formation and Ordovician limestone aquifers, while the knowledge of aquifer hydrogeological features in the whole mining area is still insufficient. Based on complimentary hydrogeological exploration for integrated coalmine areas in Liulin County,through studies on Liulin mining area aquifers groundwater hydrochemical features, further stepped up knowledge on aquifer groundwater hosting pattern impacting coal mining in the area. Thus have determined main aquifer characteristic ions in Liulin mining area, and provided basis for studies on mine water bursting sources henceforth. Meanwhile, through hydrochemical isotope characteristics have revealed Ordovician aquifer recharging, runoff and drainage conditions in the mining area. That is to say mining area groundwater recharging source is atmospheric precipitation, since mining area is situated in the lower reach of the Liulin spring area karst groundwater concentrated drainage area, thus groundwater runoff is stagnant with poor water circulation condition.
