摘 要:针对大冶铁矿尖林山采区在生产过程中出现备采矿量严重不足的三级矿量失衡问题,结合无底柱分段崩落法结构参数与采场特点,通过优化原有施工设计,在部分回采进路中部增加切割平巷和切割天井,开凿切割槽等合理布置切割工程的措施,调整施工作业安排,增加备采矿量,均衡三级矿量,同时改善矿块通风条件,提高采矿生产效率,有效地保证了矿山持续均衡生产。The arrangement of reasonable cutting engineering,such as adding cut drafts and raises,cutting slots in some mining entrances,and the regulation of production schedule were made for settling unbalance problem of three grade reserves in the production process of non-pillar sublevel caving method,With these measures taken,the mining reserves are increased and three grade reserves are balanced.At same time the ventilation condition and the production efficiency of mining are improved.That guarantees the continuously stable production of the mine.
