Research On Mining Method Of Thin And Multilayer Ore Bodies That Sloped Slowly Of Yunnan Dayao Copper Mine

The mining method is the nuclear contents of construction, Seeking safe, high-efficient, economy, rational mining method, which is the urgent need of the mining productive construction. It is theoretical foundation that the mine carries on rational planning, economy exploiting, and safety in production.WaDiJu mineral deposit of Yunnan Dayao copper mine deposit belongs to the typical multilayer thin ore body that slowly sloped in the mineral deposits. It is extremely difficult to exploit and the exploit cost is relatively high. This article aims at this complicated ore body, combines to the practice of Yunnan Dayao copper mine. In line with science, security, economic principle, carries on the deep discussion and studies from each link of exploiting the technology and breach some routine thinking modes. Basing on "virtual empty district", the detail study has done to open-up way, mining methods and the way disposed of empty district and present rational mining method. The on-the-spot production practices indicate that effect is obvious and have general application prospects.
