摘　　要：棉絮铺尾矿库位于云南省澜沧县西北部岩溶地区,岩溶裂隙发育,对周边环境造成了一定程度的污染。通过对尾矿库的水文地质调查及钻探勘察,查明了库区的区域地质构造、地形地貌、地层岩性及水文地质条件,并进行了地表水、地下暗河及溶洞对库区的影响分析。结果表明:该尾矿库库区地形条件复杂,松散含水层空间分布不稳定,地下水及场地土对混凝土结构具有弱腐蚀性,总体较适宜进行工程建设;但尾矿库建设受到岩溶、滑坡及地下水的影响。Mianxupu Tailings Pondis located in the karst area in the northwest of Lancang County,Yunnan Province.The development of karst fissures has caused a certain degree of pollution to the surrounding environment.Through the hydrogeological survey and drilling survey of the tailings reservoir,the regional geological structure,topography,lithology and hydrogeological conditions of the reservoir area were identified,and the influence of surface water,underground river and karst cave on the reservoir area was analyzed.The results show that the terrain conditions of the tailings reservoir area are complex,the spatial distribution of the loose aquifer is unstable,the groundwater and the site soil are weakly corrosive to the concrete structure,and it is generally suitable for engineering construction.However,the construction of tailings reservoir is affected by karst,landslide and groundwater.
