铜绿山铜铁矿矿井下端部小矿体开采研究

Study on the Mining of the Periphery of the Main Ore Body underground Small Ore Body in Tonglushan Copper-iron Mine

在铜绿山矿危机矿山资源勘查工作中发现井下主矿体周边分布大量小矿体,矿体品位较好,具有一定的开发价值。本文充分利用矿山现有的提升、运输、通风、排水等系统,利用矿山现有成熟的采矿工艺,对井下-605m中段以上小矿体,在确保安全的条件下,进行开采方案研究,合理利用原有系统进行开拓延伸,通过有效利用原有巷道工程,对端部小矿体最大限度地进行开采利用,实现端部小矿体利益最大化。其次是补充相应中段的采出矿量,降低中段下降速度,延长中段服务年限。

With the Tonglushan mine exploration mining resources crisis in the periphery of the main ore body underground large number of small ore body, ore grade is better, it has a development value. In this paper, we make full use of the existing mine lifting, transport, ventilation, drainage and other systems, the use of existing mature mines mining technology, the underground -605m above the middle of the small ore, to ensure safe conditions, the mining plan study, rational use extend the original system to develop, through the effective use of existing roadway project, carried on the ends of small ore exploitation to maximize, maximize ends of small ore interests. Followed add the appropriate amount of ore mined middle, lower middle rate of decline, extend the service life of the middle.
