摘要
经济合理剥采比是确定露天开采境界、衡量开采经济效益的一项重要技术经济指标。介绍了储量盈利比较法的适用条件及计算方法,并以实例说明利用储量盈利比较法计算经济合理剥采比时,除考虑露天开采与地下开采的经营成本及税费的差别外,亦应考虑可比建设投资的影响。
Economic and reasonable stripping ratio is an important technical and economic indicator to determine open-pit mining limit and measure mining profits. The paper introduced the applicability conditions and calculation of reserve profit comparison method and argued based on real cases that when the comparison method is used to calculate economic and reasonable stripping ratio,the influence of comparable construction investment should also be taken into consideration besides the running cost and taxation differentiation between open-pit and underground mining operations.
