摘要
在调查研究老窿残矿赋存现状的基础上 ,结合矿山生产实际 ,提出采用穿脉群回采 ,该法通过几年的应用实践 ,取得了显著的经济效益。
The occurrence of orebody with remained old mining workings has been investigated and studied.In consideration of using existing conditions of operation,a right method(outside vein tunnel with short roadways across the vein)for extracting such a kind of orebody has been found.This mining method can be taken by other similar mines for reference.
