从六十年代中期,随着柴油轮胎设备在地下矿使用迅速增加,澳大利亚某些矿山已用柴油卡车经斜坡道运矿到地面。1966年以来,澳大利亚的联合金矿公司所属矿山已采用这种运输方式。最近11年内,为了降低成本和从更深处开采时能取得更好的经济效果,设备的规格和类型都已经更新。叙述了从小型地下专用设备换成大型普通越野卡车的这些变化,并详述了提高生产能力的效果。对于年产量达到100万吨的浅部矿体,初期用斜坡道开拓和卡车运输,成本优于竖井开拓。本文对此进行了叙述,并比较了两种方法的成本。关于把斜坡道矿山应当改为竖井提升方案的深度问题也进行了讨论,并且把以贴现现金流量法(D.C.F)为基础的预算与现有经验结果进行了比较。在这个比较中,介绍了一个把这两个方面结合考虑的解决办法。
Since the mid-1960s, with the rapid increase in the use of diesel tire equipment in underground mines, some mines in Australia have been mined on the ground with diesel trucks using ramps. Since 1966, Australia’s coal mining company affiliated mine has adopted this mode of transport. In the last 11 years, equipment specifications and types have been updated to reduce costs and achieve better economics when mined deeper. Described the changes from a small underground dedicated equipment to a large general purpose off-road truck, and described in detail the effect of increasing production capacity. For shallow ore bodies with an annual output of 1 million tons, initial ramp-up and trucking operations will outweigh the cost of shafts. This article describes this and compares the costs of both approaches. The issue of the extent to which ramp mines should be converted to shaft hoisting schemes was also discussed and the budget based on the discounted cash flow method (D.C.F.) was compared to the current experience. In this comparison, a solution that combines these two aspects is presented.
