Optimal Design of Waste-Dump Slope of Open Pit Mine Based on Strength Reduction FEM
Based on strength reduction theory, finite element method (FEM) was selected to analyze the potential destroy mode of some waste-dump slope of open pit mine in Tongchuan city of Shanxi province. Slippage surface develop character and corresponding safety factor variation disciplines under different slope height and angle also were obtained. According to principle of the maximal bear volume, the optimal slope height and angle would be defined, the potential destroy mode showed that waste-dump slope shoulder belongs to tensile failure, and waste-dump mass slides like a circle spoon, and slippage surface incise the bottom rock when the slope height reached some value. Slippage scope enlarged with the slope height increasing under the natural condition, and slippage surface trend rearward. Comprised with the natural condition, depth and scope of slippage surface was bigger under saturation condition. So the optimization design has important economic effects for reducing land occupation and increasing the maximum waste-dump capacity.
