金属矿山露天转地下开采的研究现状与措施

Research Status and Measures for Transformation of Open-pit Mining to Underground Mining in Metal Mines

由于国家经济高速发展,对各类矿产的消耗日益增多,我国矿产资源逐渐减少,金属矿山将经历露天转地下的开采过程。特别是对于那些连续性较差、直接顶板稳固性不好以及宽体的金属矿山,必然会采用露天转地下开采方式,这类金属矿山在开采的过程当中非常容易发生顶板脱落的安全事故,对采矿人员造成了严重的生命威胁。因此最近几年,广大学者对金属矿山的露天转地下开采存在的问题以及解决方法继续进行深入的研究。

Due to the rapid development of China's economy and the increasing consumption of various types of minerals,China's mineral resources are gradually decreasing.Therefore,inevitably metal mines need to go through the transformation from open-pit to underground mining process.Especially for those metal mines with poor continuity,poor stability of the direct roof and wide body,it is bound to adopt the transformation from open-pit mining to underground mining method,because such metal mines are very prone to safety accidents in which the roof falls off during the mining process,posing a serious life threat to the mining personnel.Consequently,in recent years,many scholars continue intensive research on the problems and solutions for the transformation from open-pit mining to underground mining in metal mines.
