损失、贫化是矿山开采的重要技术指标,它的高低是衡量矿山开采技术水平和管理水平的重要标志之一。但是在几十年的矿山开采过程中,我们对这两个重要的技术经济指标,既没有系统准确的统计计算,也没有全面系统的综合分析研究,寻求经济上合理、技术上可行的损失、贫化指标。随着国民经济和科学技术的发展,技术水平和管理水平的不断提高,才有可能将分
Loss and depletion are important technical indicators of mining, and its level is one of the important indicators to measure the technical level and management level of mining. However, during the several decades of mine exploitation, we have neither systematic and accurate statistical calculation nor comprehensive and systematic comprehensive analysis and research to find economically reasonable and technically feasible losses, Dilution index. With the national economy and the development of science and technology, continuous improvement of the technical level and management level, will it be possible to divide
