摘要
针对呷村银多金属矿矿体赋存情况,提出具体可行的采矿方案。推荐使用分段空场法和留矿采矿法进行采矿,通过对井下采矿作业的工艺调节,满足选矿厂的不均衡供矿。4100m以上选用平硐溜井开拓系统,4100m以下选用盲竖井开拓系统。采用分期开采,前期主平硐设在4100m水平。矿山运输采用架线机车,矿石、废石均采用同一型号侧卸式矿车,有利于生产调度。
The applicable scheme of mining engineering for Guacun mixed silver deposit in Sichun, China is programmed based on the geological condition of the ore body. The combination of sublevel stoping and shrinkage stoping is proposed. The inharmoniously demand of ore for concentrator can be met by modulating the mining process. The development systems are the adit and pass above 4100m level, and underground shaft under 4100m. Mine exploit is divided into several phases. In the first phase, main adit is located at 4100m. The ore and waste are transported by trolley locomotive and same type of side dumper.
