Outline
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 (Ⅱ) and an aquifer (Ⅲ). When the mine is pushed to a level of 1 300 min the third year of production, the underground water inflow is the smallest. When the mining level reached 1 270 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 23 152 m3/d and 46 552 m3/d respectively. The research results can provide important data support for the development of subsequent waterproofing and drainage plans for the mine.
