摘　　要：为准确预测刚波夫主矿体露天矿揭露含水层后的矿坑涌水量,结合矿山已有水文地质资料开展矿山现场抽水试验,基于大井法中的承压转无压公式计算了矿山不同开采年份的矿坑涌水量。依据现场水文地质资料和抽水试验结果,将主矿体分为强富水区(Ⅰ)、中等富水区(Ⅱ)和隔水层(Ⅲ);矿坑在生产第3年推采至1 300 m水平时,地下涌水量最小;在生产第6年推采至1 270 m水平时,地下涌水量达到最大值;结合正常雨季和暴雨季降雨量,计算矿坑总涌水量分别可以达到23 152 m^(3)/d和46 552 m^(3)/d。研究结果可为该矿山后续的防排水方案制定提供重要的数据支撑。In order to accurately predict the mine water inflow after exposing the aquifer in the open-pit mine of the main ore body of Kambove mine,the mine field pumping test was carried out in combination with the existing hydrogeological data of the mine,and the mine pit water inflow in different mining years was calculated based on the pressure bearing transfer to no pressure formula in the large well method.Based on field hydrogeological data and pumping test results,the main ore body is divided into strong water-rich zone(I),medium water-rich zone(I)and an aquifer(II).When the mine is pushed to a level of 1300 m in the third year of production,the underground water inflow is the smallest.When the mining level reached 1270 m in the sixth year of production,the underground water inflow reached its maximum value.Combined with the rainfall in normal rainy season and rainstorm season,the total water inflow of the mine pit can reach 23152 m^(3)/d and 46552 m^(3)/d respectively.The research results can provide important data support for the development of subsequent waterproofing and drainage plans for the mine.
