摘要
经济合理剥采比是确定矿床露天开采的一项重要经济技术指标。本文考虑的主要影响因素有开采深度、矿物岩石硬度、矿石品位、矿石采出率、选冶回收率、安全事故损失和边坡治理费用等。简单讨论了市场因素对经济合理剥采比的影响。
Economic and reasonable stripping ratio is an important technical and economic indexes of opencast deposit. The main influence factors considered in this paper are mining depth, mineral rock hardness, ore grade, ore recovery rate, safety accident loss of dressing - metallurgy and overhead expenses, etc. This paper simply discusses factors of market economic rational stripping ratio.
