某矿-460m至-580m中段开拓方案研究

Study on Development Plan of the Section from Level -460 m to -580 m in a Mine

根据某矿Ⅰ#矿体赋存状态,研究-460m至-580m中段矿体回采顺序并制定了几种可能的阶段开拓方案。通过对这几种开拓方案进行经济技术综合比较分析,最终确定为自下而上的上行式阶段回采顺序,开拓方案选择在-520m和-580m中段布置阶段开拓巷道,阶段高度为60m,分段高度为20m。

The mining sequence from level -460 m to -580 m ofⅠ# orebody is researched according to its occurrence con dition.Over head mining sequence is determined after economic and technical comparison of several possible development plans.The development roadways are laid out in -520 m and -580 m level,with the level height of 60 m and the sublevel height of 20 m.
