Numerical Simulation for Karst Water Drainage of an Iron Mine

An iron mine in Fujian that is mining a hydrologically complicated deposit with karst water, faces the problems of high water pressure and unclear inflow. Therefore, it’s imperative to predict mine discharge exactly. The 3D finite element simulation model is established basing exploration data and theoretical analysis results, which gives exact generalization of special hydrogeology elements such as fault zone, karst springs, surface water leakage and chamber for dewatering. At last, the effect of dewatering scheme are evaluated for +300m.
