Analysis of the Influence of Soil Disturbance Reconstruction on Groundwater Recharge in Non-metallic Mines
Soil disturbance and reconstruction in non-metallic mining area will change the hydrogeo-logical environment and lead to inaccurate analysis results of groundwater recharge.From the perspectives of soil thickness,soil temperature and surface runoff,the influencing factors of soil disturbance reconstruction on groundwater recharge were analyzed,a three-dimensional groundwater flow model was constructed,and then a numerical model of the influence of soil disturbance reconstruction on groundwater recharge was con-structed,and the evolution formula of water level and the relationship between infiltration coefficient,water content and water level were obtained.The results show that the soil disturbance reconstruction method in the study area has a certain promotion effect on the soil moisture content over 100 cm,and the groundwater level generally presents a trend of first rising and then decreasing,which provides a scheme for solving simi-lar problems in the mining process of other mines.
