摘要
Ⅱ号多金属矿体属缓倾斜厚矿体 ,矿体最厚部分在 - 5 0m水平 ,在 - 44～ - 5 4m之间留有 10m厚水平矿柱。本文针对该水平矿柱的回采方案研究及生产实践作了概括性介绍 ,并对回采现场的相关问题处理作了阐述。
No.2 polymetal ore body is a thick and slightly inclined one with the thickest part at -50m level and there were 10m thick level pillars left between -44～ -54m levels.A general introduction of the study of this level pillar extraction scheme and the production practice is made and the treatment of the problems occuring on extraction site are described.
