摘　　要：为了合理开采兴国县梅窖镇大石岭矿区石灰岩、保障当地供水水源安全,本文通过物探、钻探及连通试验等方法,对该区岩溶地下水特征进行了研究。结果表明:研究区岩溶发育以溶孔、溶槽及溶洞为主,主要集中在高程296~265m;岩溶地下水运动方向以北东、北东东方向为主,北西方向运动受阻;考虑到开采对岩溶地下水的影响,建议将原定设计最低开采高程提升至307m附近,并在暗河出口北东方向上寻找更为充沛的供水水源,确保矿区周边居民生产生活用水安全。In order to exploit limestone reasonably in Dashiling mining area of Meijiao Town,Xingguo County and ensure the safety of local water supply,the characteristics of karst groundwater in this area were studied by geophysical exploration,drilling and connectivity test.The results show that the karst development in the study area is mainly composed of dissolution pores,grooves and caves,mainly concentrated in the elevation of 296〜265m.The movement direction of karst groundwater is mainly northeast,while the karst groundwater movement is blocked in northwest direction.Considering the impact of mining on karst groundwater,it is suggested to raise the minimum mining elevation to around 307m?and look for more abundant water sources in the northeast of the anhe outlet to ensure the safety of production and living water for the residents around the mining area.
