Prediction of the inflow water into a pit in a semi-infinite zonal aquifer under the condition of constant water head

Based on the analysis of hydrogeological conditions of a calcite mine area in Guangxi Autonomous Region,China,a hydrogeological model was generalized,and a formula for a complete penetrating well flow in a semi-infinite zonal aquifer with a constant recharge water head has been deduced.The formula is used to predict the inflow of water into the pit.The traditional method of interferential wells is used to validate the evaluation result.The results show that both the results are extremely closed under the condition of large numbers of projection times.However,using the formula is more convenient compare the stacking method of interferential wells in terms of calculation methods.
