矿石损失与贫化,共同反映地下资源的利用程度,并对矿床开采的技术经济效果有极其不良的影响。为了正确计算矿石损失与贫化,必须建立切合实际的理论和方法。现用的计算矿石损失与贫化的理论和方法,是五十年代初期从外国传来的。二十多年来,我国曾结合生产实际,做了某些改进,但是仍然未从根本上解决问题。本文针对原有的矿石损失与贫化计算方法存在的问题,加以整理,以期提出合理的计算方法。在这个计算方法中,既不分为废石含有用成分和不含有用成分两种
Loss and depletion of ores together reflect the degree of utilization of underground resources and have an extremely adverse effect on the technical and economic performance of the deposit. In order to correctly calculate the ore loss and depletion, we must establish realistic theories and methods. The existing theories and methods for calculating the loss and depletion of ores have come from foreign countries in the early 1950s. For more than two decades, our country has made some improvements in the light of actual production. However, it still has not fundamentally solved the problem. In this paper, the problems existing in the original ore loss and depletion calculation methods are rectified in order to propose a reasonable calculation method. In this calculation method, it is neither divided into waste rock containing ingredients and non-use ingredients
