【Abstract】 To reduce the error in the calculation of underground waterinflow in mine, the kinematic characteristics of underground water in deep water pumping and draining from thick weakly water-carrying stratum are analysed and a numerical coupling model of 2-dimensional flow for area and 3-dimensional flow for mining district is proposed for waterinflow calculation. The underground waterinflow of Beiminghe Iron Mine is recalculated with the model, with the result close to the real value and the operation sequence simplified.更多还原
