摘要
为解决目前地下缓倾斜中厚磷矿开采机械化程度低、资源回收率低等问题,根据矿层赋存状况及顶底板的条件,从矿体赋存条件及矿体强度特征探讨了综合机械化开采技术在磷矿中的可行性,研究了机械在深部高应力下的破岩机理,最后探究了综合机械化采矿技术及工艺在该矿层的具体应用。
In order to solve the problems of low mechanization and low resource recovery rate of underground gently inclined medium-thick phosphate ore mining,according to the condition of the deposit and the conditions of the roof and floor,the feasibility of fully mechanized mining technology in phosphate rock is discussed from the ore body occurrence conditions and ore body strength characteristics,study the mechanism of mechanical rock breaking under high stress in deep,finally,the specific application of fully mechanized mining technology and technology in this ore layer is explored.
