The layout of the dewatering system in open-cast mining must be adapted to assumptions and size expected inflows, which, turn, depend on natural conditions operation other mines groundwater intakes, affecting arrangement hydrodynamic field. This case study analyses possible solutions related a change drainage system: decommissioning by flooding depleted deposit new one located vicinity. As part...
This paper mainly analyzes the stability of waste dump Zijinshan open-pit mine. ANSYS software was used to establish numerical model slope according geological report and real geographic conditions. The displacement, stress, plastic deformation in X Y directions under different number overburden layers strength reduction factor were obtained, so as obtain safety give operation measures.
