需要进行露天开采的矿山,在做矿山开采设计时,需要确定经济合理的露天开采境界。经济合理剥采比就是确定露天开采合理境界,衡量开采经济效益,贯彻“优先发展露天开采”技术经济政策的一个重要技术经济指标,也是矿山开采设计中的一个基本理论问题。它的正确与否,它是否能客观地反映矿山开采中的实际情况,主要决定于其计算方法。科学地计算经济合理剥采比,对提高矿山素质,提高经济效益有重要意义。经济合理剥采比,在不同情况下它是一
The need for open-pit mines, mining mining design, the need to determine the economic and reasonable realm of open-pit mining. Economic rationality is an important technical and economic index for determining the reasonable realm of open-pit mining, measuring the economic benefits of mining, and implementing the technical and economic policies of “preferential development of open-pit mining”. It is also a basic theoretical issue in the design of mining. Whether it is correct or not, whether it can objectively reflect the actual situation in mining, mainly depends on its calculation method. Scientifically calculating the ratio of economic and rational stripping is of great significance to improving the quality of mines and improving economic efficiency. Economic and reasonable stripping ratio, in different circumstances it is one
