边角煤回收巷道布置及回采工艺分析

摘要

The re-mining of leftover coal has been a new problem for many coal mines,based on many years of re-mining of the author,the paper analyzes the tunnel layout of different leftover coal recovery and re-mining techniques,which will be of referential value for the recovery in coal mines,especially old ones.%边角煤回采已成为目前许多煤矿面临的一个新课题。结合笔者多年残采工作经验,对不同条件边角煤回收的巷道布置及回采工艺进行了深入分析,对矿井尤其是衰老矿井回收边角煤有借鉴意义。
