Abstract

Mining involves many operations such as rock breakage, materials handling, equipment maintenance, mine design, scheduling and budgeting. At one stage or the other mine managements often have to decide whether to undertake a major mining operation using their own equipment and personnel or to contract the operation out to a specialised mining contractor. By contracting out one or more of their mining operations, the mining companies can concentrate on their core businesses. This paper reviews contract mining and owner mining to determine the merits and demerits of each and how they affect the economies of the mining companies. The results show that the decision to adopt owner mining or contract mining is influenced by the life of the mine, the availability and use of capital, and that contract mining helps to reduce the cost of mines with short life spans. The general trends in the mining industry show that contract mining will be the way forward for most mines under various circumstances in the future.

合同挖矿与所有者挖矿——未来之路*
采矿涉及许多作业,如岩石破碎、物料搬运、设备维护、矿山设计、调度和预算。在某一阶段,矿山管理部门往往必须决定是使用自己的设备和人员进行重大采矿作业,还是将这项作业承包给专门的采矿承包商。通过将一项或多项采矿业务外包出去,矿业公司可以专注于其核心业务。本文对合同采矿和业主采矿进行了回顾,确定了各自的优缺点以及它们对矿业公司经济的影响。研究结果表明,矿山是采用业主开采还是合同开采,受矿山寿命、资金可用性和使用情况的影响,合同开采有利于降低矿山寿命短的成本。采矿业的总体趋势表明,在未来各种情况下,合同采矿将是大多数矿山的前进方向。
