最佳采矿方法必须技术上可行而经济上最合理。本文以典型实例论证了对具体矿床的适应性在采矿方法技术性比选中的重要性,并综合考虑那些作为采矿方法经济评价的成本、盈利、工业储量开采损失与贫化以及劳动生产率诸指标,提出了采矿方法效率系数作为采矿方法的经济评价准则。采矿方法效率系数η综合考虑了自然的、工艺的和经济的因素,综合考虑了安全适用、低贫损、高生产率、低成本这一基本要求,明显地提出了寻求高效率采矿方法的途径。 The best mining method must be technically feasible and economically sound. This paper demonstrates the importance of adaptability of specific deposit in the technical comparison of mining methods with typical examples and considers all the indexes which are the cost, profit, mining loss and depletion of industrial reserves, and labor productivity The Efficiency Coefficient of Mining Method as Economic Evaluation Criterion of Mining Method. The efficiency coefficient η of the mining method comprehensively considers the natural, technological and economic factors. Considering the basic requirements of safety, low loss, high productivity and low cost, it is obvious that the ways of seeking efficient mining methods are obviously proposed.
