摘要/Abstract

摘要： 针对“剥岩高峰”对矿山生产带来的不利影响，研究了设备配置更新策略与露天开采外委剥离的优化问题.基于铲运设备的运营成本与生产能力随设备役龄变化的关系，建立了决策单台设备退役时间的动态经济寿命计算模型，并根据此模型给出了具体的设备配置算法步骤.设置一系列不同的矿山自剥离量与外委剥离量的分界水平，计算各分界水平条件下的外委单价可行区间，然后在区间内确定外委商谈价格并分析得出与之对应的总成本净现值最低的外委方案.实例计算证明，采用该方法减少设备投资的成本要高于外委岩石剥离成本.

关键词: 剥岩高峰, 外委, 经济寿命, 设备配置更新, 单价可行区间

Abstract: 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.

Key words: stripping peak, outsourcing, economic life, equipment update, feasible range of unit cost
