Based on the geological and hydrogeological conditions of the Pingshuo mining area, a regional hydrogeological conceptual model is constructed. Using the finite difference method, the draft module and well module in MODFLOW are used to simulate the groundwater level in the Pingshuo mining area under current mining conditions. The model is calibrated using existing measured data. Then, the coal mine is shut down to restore its natural unmined groundwater level, and the natural groundwater flow field in the Pingshuo mining area is inverted. Finally, based on historical coal mining and distribution, the impact of different mining modes on the groundwater flow field under coal mining driving is simulated.
Negotiate with mining staff to obtain and conduct field surveys.
Based on the finite difference method, simulate the groundwater level, and then calibrate the model to invert the groundwater flow field.
The data quality is good.
