摘要：

Since the "stripping peak " has a negative effect on mine production, the tactics of equipment update and the optimization on stripping plan of outsourced open-pit mines were studied. Based on the relation between the cost of stripping equipment, the production capacity and the changing of the service age, a dynamic economic life model was established to decide the retire time of a single equipment. Meanwhile, the configuration algorithm steps of a specific equipment was also given out. First, a series of different levels of mine stripping and outsourced stripping boundaries were set to calculate the feasible range of unit cost for the outsourced program, then the outsourced contract price was determined in the feasible range; Finally, based on the contract price, the net present value of the total cost was analyzed to get the optimized outsourced plan. It is proved that the cost of reducing equipment investment by this method is higher than the cost of outsourced rock stripping. © 2018, Editorial Department of Journal of Northeastern University.
