摘要
无底柱分段崩落法在和睦山铁矿开采过程中遇到通风困难、爆破效果差、巷道变形严重、回收率低等诸多问题。从5个方面提出了改进和优化措施,对结构参数和生产工艺等进行调整,取得了很好的效果。
Many problems like difficult in ventilation, poor blasting effect, serious deformation of roadway, low recovery rate existed in mine process of Hemushan Iron Ore by non-pillar sublevel caving. Improvement and optimization measures were proposed from five aspects, adjustments were done on structure parameters and production technology and so on, good effect obtained.
