摘要
分析了非均匀崩落矿岩在放矿过程中的流动特点以及无底柱低贫化放矿方式 .通过立体物理模拟放矿实验 ,对矿岩散体非均匀度对低贫化放矿方式截止放矿贫化率的影响进行了研究 ,并将研究结果应用到白银铜矿生产实践中 。
Based on the analysis of the movement characteristics of heterogeneous caved ore and rock in the process of drawing, a drawing system of low dilution and dissipation was put forward. Through the 3D physical simulation of drawing, the effect of the heterogeneous degree of caved ore and rock on the cut off dilution was investigated. Furthermore, this drawing system with the characteristic of low dilution and dissipation has been successfully used in Baiyin Copper Mine.
