摘要
根据后和睦山铁矿1号矿体地质特征、散体流动参数和点荷载强度测试结果,研究应用矿岩冒落规律和散体流动规律,提出了诱导冒落、设回收进路、采用组合放矿方式的无底柱分段崩落法高效开采方案,取得了较好的应用效果。
According to the geological characteristics, testing results of granule flow parameters and the point-load strength of No 1 ore-body in Houhemushan iron mine, the rule of ore-rock falling and granule flowing are investigated and utilized. A high efficient scheme of sublevel caving without sill pillars is put forward, which adopts the induced falling techniques and footwall drifts and combined ore-drawing modes. The method has been put into operation, and better-applied effect is obtained now.
