通过地球物理勘探、水文地质调查、钻孔和抽水试验，结合区域水文、气象、地质和水文地质等资料，求得了矿体上部盖层裂隙岩溶水水文地质参数，且对裂隙岩溶水水量进行了计算；以“大井法”为主对矿坑涌水量进行了预测，基本查明了矿区东部的水文地质特征；阐述自然条件下裂隙岩溶水对基岩裂隙水的补给微弱；当水动力条件发生改变时，易造成盖层裂隙岩溶水下渗溃入坑道，对下部矿体的开采将产生较大威胁。

Through geophysical , hydrogeological investigation , drilling and pumping tests , combining with regional hydrological , meteorological , geological and hydrogeological and other information , hydrogeological parameters of fracture-karst water in the upper part of the cover have been obtained , and karst water amount has been calculated as well.By using "big well method", the mine water inflow has been predicated , and basic hydrogeological char-acteristics of eastern mining area have been identified .It is said that under natural conditions , discharge of frac-tured karst water to basic rock fissure water is weak;when hydrodynamic conditions changed , fractural karst water could easily lead into the tunnel collapse , and will produce a greater threat to the exploitation of the lower part of the ore body .
