在开采中应尽量减少损失率,降低贫化率,充分合理地利用矿产资源,但这里有许多理论上实践上的问题尚须继续讨论和研究。现归纳为三个问题分述于下: 一、提高认识损贫指标虽不是矿山生产中的主要指标(在有色、黄金矿山是主要指标),但它是必要的技术经济指标。其目的是使有限的资源得到合理开采,也反映矿山开采质量和生产管理水平的好坏。 In mining, losses should be minimized, the rate of depletion reduced and the use of mineral resources fully and reasonably made. However, there are many theoretical and practical problems to be discussed and studied. Now summarized in the following three issues: First, to raise awareness Index of Poverty Alleviation Although not the main indicator of mine production (in nonferrous metals, gold mines are the main indicators), but it is an essential technical and economic indicators. Its purpose is to make the limited resources be properly extracted, but also reflect the quality of mining and production management level is good or bad.
