浅谈排山楼金矿露天转地下开采生产能力的实现

Preliminary discussion on the change of mining technique from open pit mining to underground mining in Paishanlou gold mine

露天转地下开采技术中,平稳过渡、安全防水、生产能力的实现显得十分突出。文中结合排山楼金矿的实际,分析了实现1 800 t/d生产能力存在的问题,并从施工队伍选择、分区开采、中段运输、采矿方法、孔底起爆技术等方面介绍了生产能力的实现,值得类似矿山借鉴。

In the change of mining technique from open pit mining to underground mining, the realization of smooth transition, safety, waterproof and designed mining capacity are the main problems. Combining with the actuality of Paishanlou gold mine, the issue analyzed the safeguard mechanism to realize the mining capacity of 1 800t/d in the following aspects, the selection of construction teams, block mining, midsection haulage, stoping method and bottom priming technique.
