大型矿用汽车管理及成本管控系统的创建与实施

Establishment and Implementation of Management and Cost Control System for Large Mine Vehicles

大型矿用汽车是目前露天矿山主要运输工具,其运营成本占到整个矿山生产成本近70%,特别是露天矿山进入深凹开采后,随着采掘深度的加大和运输距离的加长,运输成本逐年上升导致矿山运营整体经济效益逐年下滑。为解决这一问题,矿山企业一方面可以从技术层面采用胶带运输替代汽车运输的技改措施解决成本上升问题,另一方面可以从管理层面构建设备日常运营过程管理体系及成本管控体系,以提升设备的运行效率和降低设备故障率,从管理中得效益。高村铁矿通过对大型矿用汽车实施定人定机管理模式辅以车辆日成本分析及备件全寿命跟踪管控,运用管理手段降低矿用汽车运营成本,单位成本下降幅度达到15.34%,而且整个生产工序上下游效率由75%提升至82.74%,提效幅度达到7.74%,铁矿节约成本达到近800万元/a。通过1 a来的实践和探索,不但健全了矿用汽车的运营管理体系,而且达到了从管理中得效益的预定目标,可供同类矿山日常生产成本管理参考与借鉴。

Large mining vehicles are the main means of transport in open pit mines at present,and their operation cost accounts for nearly 70%of the production cost of the whole mine,especially after open pit mining,with the increasing of mining depth and the lengthening of transportation distance,the transportation cost increases year by year,which causes the overall economic benefit of mine operation to decline year by year.In order to solve this problem,on the one hand,mining enterprises can adopt belt conveyor replacing motor transport technical measures to solve the problem of rising costs from the technical level of,on the other hand,which can build equipment daily operation process management system from the management level and the cost control system to enhance the equipment efficiency and reduce equipment failure rate,so as to benefit from the management.Gaocun Iron Mine implements the management mode of man-and-machine,supplemented by the daily cost analysis of vehicles and the whole-life tracking control of spare parts for large mining vehicles,the operation cost of mine automobile is reduced by means of management.The unit cost decreased by 15.34%,the upstream and downstream efficiency of the whole production process increased from 75%to 82.74%,and the efficiency increased by 7.74%.Nearly 8 million yuan per year is saved of the mine.Through the practice and exploration of one year,not only the operation management system of mine cars is improved,but also the predetermined target of benefits from management is achieved,which can be used for reference and reference for daily production cost management of similar mines.
