采矿损失贫化管理的探讨

Discussions on management of mining loss and dilution

采矿损失率和矿石贫化率是表征一个矿山企业采矿技术水平和管理水平的重要参数。通过焦家金矿的历史数据透视,分析了矿产资源开采中损失贫化大的根源,并提出了解决损失贫化大的有效途径:选择合理的采矿方法,制定并执行可行的管理制度,严格执行《矿产资源法》,确定合理的采矿经济技术指标。

Mining loss and dilution are important indices that demonstrate the technology level of mining and management level of a mine. By analysis of the historic data of Jiaojia Gold Mine, the main reasons of higher mining loss and dilution are discussed, and effective approaches to solve these problems are suggested： i. e. , to choose sensible mining method, set up and carry out feasible management regulations, strictly implement The Mineral Resources Act, and set up reasonable techno-economical parameters for mining operation.
