广西大新锰矿缓倾斜薄矿体房柱法采矿探实

Room and Pillar Mining of Gently-inclined Thin Orebody in Daxin Manganese Mine,Guangxi Province

广西大新锰矿是典型的沉积型矿床,其西部缓倾斜矿段矿体薄、夹石厚、断层多、节理发育、褶皱强烈,破坏了矿岩的连续性、稳固性,回采难度大。通过对该矿段回采方案变化前后的实施效果进行对比,对该类矿体的采矿方法进行了探讨。

Daxin Manganese ore is a typical sedimentary type deposit. The ore body of the gently inclined ore section in the west is very thin. It is of thick rocks in many faults with very strong joints and strong folds, which destroys the continuity and stability of ore and rock. It is difficult to exploit. In this paper, the mining method of this type of ore body is discussed about by comparing the implementation effect of the mining plan before and after the change in this area.
