摘要
经济剥采比是确定露天矿境界的重要因素。通过当前计算经济剥采比原则的分析,以市场经济条件为指导,得出了以价格法为依据确定经济剥采比更为合理。对以价格法为依据确定经济剥采比的计算公式中,指出了经济剥采比的计算原则中过去没有考虑到的露天矿最低盈利要求、复垦费用、回采率、安全系数,在综合考虑以上影响露天矿的重要因素后,提出了综合因素剥采比的新概念。结果表明,将对露天采矿境界的确定提供理论支持。建议将确定露天矿境界的原则修正为:境界剥采比等于综合因素剥采比。
Economic stripping ratio is an important factor that determines surface mine ambit. This paper brought the idea that to determine economic stripping ratio according to the Price Law was more reasonable after a analysis of the principles of calculating economic stripping ratio under the guide of market economy situation. On the basis of the economic stripping ratio calculating formulas according to the Price Law, the author pointed out that the previous formulas did not take lowest profit of surface mines, cost of recla- mation, recovery ratio, and safety factor into account. After comprehensively considering the above essential factors that affect sruface mines, the author presented a new concept called reasonable economic stripping ratio, which will give a support to the establishme.nt of surface mine ambit. Based on what are mentioned above, the author suggested to modify the principles that determine surface mine ambit into the one that ambit stripping ratio equals to reasonable economic strippin ratio.
