在确定露天开采范围时,经济合理剥采比是做为反映经济因素的一个控制指标。通常情况下,它与政治要求、自然条件、技术经济条件等因素结合起来,综合确定露天开采范围和选择开采方法。但是,在满足其它因素的情况下,常常用它来初步确定一个矿床是否用露天开采、选择开采方法和确定露天开采境界。这样一个重要指标的确定原则和方法以及其应用,都存在着值得深入探讨的问题。《有色金属》“矿山部分”1976年第五期发表的彭兆德同志“关于金属矿床露天开采经济合理剥采比的计算和应用问题”一文(以下简称“计算和应用”)结合实际,全面讨论了这个问题;同时对于我写的“确定露天开采范围的合理原则”〔《有色金属》“采矿部分”1974年第五期〕一文,提出了值得深思的问题,很受启发。笔者愿意就确定露天开采范围的合理原则的问题,再谈一些看法。
In determining the scope of open pit mining, the economic rationality of stripping is a reflection of economic factors as a control indicator. Under normal circumstances, it is combined with political requirements, natural conditions, technical and economic conditions and other factors to comprehensively determine the scope of open-pit mining and selection of mining methods. However, where other factors are met, it is often used to initially determine whether a deposit is to be mined in the open air, to choose a mining method, and to determine the realm of open pit mining. The principle and method of determining such an important indicator and its application all have problems that deserve further discussion. “Non-ferrous Metals” “Mining” published in the fifth issue of 1976, Comrade Peng Zhaode “On the calculation and application of economic rationale stripping ratio of open pit mining metal ore” article (hereinafter referred to as “calculation and application”) with a practical discussion of At the same time, it is very inspiring for me to write a piece entitled “Rational Principles for Determining the Scope of Opencast Mining” (“Non-Ferrous Metals” “Mining Section”, Issue 5, 1974). The author is willing to talk about some questions about the reasonable principle of determining the scope of open pit mining.
