| Numerical Simulation of Structural Variation of Aquifer Effect on Regional Groundwater Circulation |
| The destruction of groundwater resources caused by coal mining is the main bottleneck restricting the sustainable development of economy and environment in coal mining area. The contradiction between min-ing of coal resources and protection of water re-sources will become more serious. China's coal-rich regions are mainly distributed in north and northwest China. Only coal reserves in Shanxi, Inner Mongolia, Shaanxi and Xinjiang provinces account for 73.1% of the total coal reserves. Groundwater resources in these coal-rich areas are relatively poor. Severe water shortage accounted for 71% of key mining areas and 40% of serious water shortages. The serious damage to underground water resources exacerbated the shortage of water resources in the mining areas, which is particularly prominent in the energy province of Shanxi. The fundamental reason is that the mining caused structural changes in aquifers, resulting in damage to groundwater resources, so that the groundwater resources from the original quality of water available for exploitation into the pit of mine water and drain away, undermine the groundwater fill row, and destroyed the hydrological surface condi-tions, undermined the surface water cycle, thus af-fecting the regional groundwater cycle situation. |
