关于露天转地下开采境界顶柱破坏模式及稳定性的研究

A Research on Wreck Form and Stability of Boundary Pillar if Changing open-pit Mining to Underground Mining

我国很多矿山由露天转为地下开采,因此境界顶柱的安全稳定就成了一个研究课题,国内外的一些相关学者都进行了研究,很多研究都取得了一些非常好的成果。通过分析露天转地下开采的特点、露天转地下开采过渡的采矿方法,对境界顶柱破坏模式和稳定性进行了研究。

In recent decades,many of the mines has transformed open-pit mining to underground mining in our country,and the safety and stability of boundary pillar has become a research topic,some related domestic and foreign have made some researches,and a lot of research has made some significant achievements.This paper analyzed the characteristics of mining transformed from underground to the open-pit,transition mining methods when transforming from underground to the open-pit,the wreck form and the stability of boundary pillar were studied.
