The Numerical Simulation Research on the Groundwater Environmental Impact of Coal Mining in Complex Boundary Conditions

Abstract:

The article takes Shanxi Lu’an Group Yuxin Coal Mines as an example, establishing a model to simulate the impact of groundwater processes in different time periods Yuxin mining process through MODFLOW software. And evaluates the predictive region groundwater level and groundwater environment changing trends run of mine production.Model fit with satisfactory results. Due to there's watershed area in groundwater exploitation and the groundwater flow along the limestone layer excretion which is in the valley around, the groundwater has three flow directions in the Mining area and the flow field is very complex.Obviously,it is more difficult to understand the mining impact on groundwater exploit ation process. The article combines theoretical study with practical investigation. According to the simulation results of Yuxin Coal Mines, showing more clearly the impact of coal mining under complex boundary conditions on groundwater. Provide for the study of the impact of post-mining groundwater reference, while providing the basis for the supervision and management of local government departments and post Yuxin coal mining operation, and also provide a favorable basis for the protection of drinking water for local residents.
