矿床开采时矿石损失和贫化计算的目的在矿床开采的过程中,由于混入了贫化岩石或劣质矿石(非平衡矿量),以及富矿在爆破时形成粉末的损失,因而造成矿石量的损失和贫化(质量损失)。这种矿石量与质量的损失原因,是与矿床地质和水文地质条件、采矿方法以及采矿作业的组织工作有关的。因此,在矿床开采过程中计算矿石损失和贫 Ore losses and depletion calculations during ore bed mining The loss of ores during the mining process resulted from the loss of ore due to the incorporation of depleted rock or low quality ore (non-equilibrium ore mass) and the loss of powder during blasting And depletion (loss of quality). The reason for this loss of ore quality and quality is related to the geological and hydrogeological conditions of the deposit, the mining method and the organization of mining operations. Therefore, ore losses and leanings are calculated during the mining process
