Numerical Simulation and Inflow Prediction by the Outflow Test of Coal Mine
This article, by using the east mining area outflow water test data of No.5 coal mine in Fengfeng coal field, presents a numerical simulation of groundwater flow and a prediction of drainage.First of all, according to the hydrogeologic condition, the groundwater seepage numerical model of this mining area is established.Then, the model is verified by using the drainage experiment data.The measured and simulated water levels of observation wells fit well during the model verification.Finally, the water inflow of the coal mine is forecasted by using the established model.The result of the prediction has shown that it is feasible for the Daqing limestone aquifer to take measures of the water discharge method for the safety mining of Shanqing coal seam below-100 m level.
