基于贴现现金流模型的矿山设备选型及应用

Mine equipment selection based on discounted cash flow model and its application

矿山设备选型关系到矿山初期成本的投入及后期的运营费用,一个合理的矿山设备既要满足技术要求又要考虑其经济性,在对矿山设备经济性评价时既要考虑设备运行成本,又要加入时间因素。以某矿山运输设备为例,建立贴现现金流模型,将2种设备选型方案购买费用及运营费用进行贴现,对满足技术选型的设备方案进行了经济性对比,进一步确定出该矿山最优设备方案为新增45 t卡车。贴现现金流法不仅适用于运输设备选型,同时也适用于矿山其他设备,能辅助技术人员对矿山设备选型进行更好的评测。

The selection of mine equipment is related to the input of the initial cost of the mine and the operation cost in the later stage.A reasonable mine equipment should not only meet the technical requirements but also consider its economy.In the evaluation of the economy of mine equipment,it should consider not only the equipment operating cost,but also the time factor.In the case study of the transportation equipment of a mine,a discounted cash flow model is established,the equipment purchase cost and operation cost of the two equipment selection schemes are discounted,and the equipment schemes that meet the standards of the technical selection are economically compared,eventually it is decided that the optimal equipment in the mine is an additional 45 t truck.The discounted cash flow method is not only suitable for the selection of transportation equipment,but also for other similar equipment in mines,and can assist technicians to better evaluate the selection of mine equipment.
