综采工作面缩面回采工艺研究

Study on Mining Technology of Shrinking Face in Fully Mechanized Mining Face

煤矿在回收边角余煤时,为减小煤柱留设和煤炭资源浪费,工作面采用不规则"刀把"布置,但增加了回采难度。通过采用随采随撤缩面技术方案和合理的施工组织,实现了安全顺利回采,为不规则工作面回采提供了借鉴和参考。

In order to reduce coal pillar retention and waste of coal resources, irregular ＂knife handle＂ arrangement is adopted in the working face of the coal mine in the recovery of residual coal at the side corner, but the diffculty of recovery is increased. By adopting the technical scheme and reasonable construction organization, the safe and smooth mining is realized, which provides a reference for the mining of irregular working face.
