根据野外地质调查、区域地质资料、实际地质勘探资料、实际物理勘探资料等，通过对大沙地尾矿库所在区域的岩溶地貌形态、岩溶发育条件、岩溶发育规律、岩溶发育强度、岩溶稳定性等分析，总结了区域岩溶发育特征，并对北衙盆地岩溶按其密集程度进行了分区；其结果表明，北衙地区岩溶发育程度属于中等偏强烈，尾矿库库区岩溶发育程度为中等偏微弱。该研究结果为预防尾矿库渗漏，确保尾矿库安全运行，提供了基础资料。
Based on field investigation,regional geological data,actual geological exploration data,actual physical exploration data, etc, and through the analysis on karst landform, karst development conditions, karst development rules,karst development intensity,karst stability and so on of the region where Dashadi tailings pond is located,the pa-per summarized the regional karst development characteristics and divided the region according to karst development intensity in Beiya basin.It is concluded that the degree of karst development in Beiya basin is medium to strong,and Dashadi tailings pond medium to weak.The research provided basis for the prevention of tailings pond leakage,ensu-ring safe operation of the tailings pond.
