某露天矿挂帮矿资源开采方案

Mining Scheme of Hanging Mine Resources in an Open Pit Mine

经过半个多世纪开采,某大型露天矿山境界内资源迅速衰减,采场面临闭坑停产压力。根据地质资料,该采场境界外尚赋存着丰富的挂帮矿资源。为了能够使这部分资源得到合理利用,结合矿体赋存条件、已经形成的生产系统等实际情况,从技术、安全和经济方面对挂帮矿体资源开采方法进行了选择分析。

After more than half a century of mining,the resources in the boundary of a large open-pit mine are rapidly degraded,and the stope faces pressure to close the pit.According to geological data,there are abundant resources for hanging and supporting resources outside the realm of the stope.In order to make this part of the resources rationally utilized,combined with the actual conditions of the ore body occurrence conditions and the established production system,the mining,mining and mineral resources mining methods were selected and analyzed in terms of technology,safety and economy.
