Contribution of Groundwater in Zhiluo Aquifer to Mine Water in Shennan Mining Area: Numerical Simulation

Illustration water sources and ratio from different aquifers has significant means to mining water management. In this paper, based on the hydrogeological data, mining water and ratio of the height of the fractured zone to the mining height of typical mine area in Shennan mining area, a numerical simulation model was set up. Totally, 7 layers including aquifer and aquiclude are contained in the model. And it predicted the groundwater flow field of Quaternary and Zhiluo aquifer groundwater in Jurassic system very well via the model calibration. Furthermore, simulation results shows that mining action affects Zhiluo aquifer groundwater directly. For example, Zhiluo aquifer groundwater contributes nearly 94.82 percentage when mining water quantity reaches 117743.52 m³/d in Ningtiaota mining area.
