在矿山企业的生产活动中,矿石损失率是反映对地下资源开发利用情况的重要指标,也是评价采矿方法和管理水平的重要内容。所以计算方法的可比性和准确性十分重要。 但在现行的损失率计算中,根据有关规定,均只计算回采损失,不考虑采切工程附产矿量这一因素,即未进行采场综合损失率(下称综合损失率)的计算。可是在通常情况
In the production activities of mining enterprises, the ore loss rate is an important indicator of the exploitation and utilization of underground resources, as well as an important part of evaluating the mining methods and management level. Therefore, the comparability and accuracy of the calculation method is very important. However, in current calculation of loss rate, only recovery loss is calculated in accordance with the relevant regulations, and the factor of ore production by cutting and cutting works is not taken into consideration. That is, the calculation of the comprehensive loss rate of stope (hereinafter referred to as the comprehensive loss rate) is not carried out. But in normal circumstances
