摘要
针对推广综放机械化开采技术无法解决的近40万t的边角煤、残留煤柱等,以煤炭资源回收问题,对矿井生产布局进行了残采布置回收开采规划,同时,针对形成的倾斜长度不足50 m的残留煤柱面倾斜长度短、难于组织高效生产实际,积极探索实践高效生产工艺,达到了提高资源回收率、高效生产的目的。
Bases on the promotion of mechanized caving mining technology without the ability to solve nearly 400,000 t boundary coal,coal pillar,etc.,focusing on improving the recovery of coal resources issues,the mine produced a residual mining lay out recycling mine planning.For the formation of tilt length of less than 50 m of residual coaltiltcy linder length was short,difficult to organize efficient production practice,the practice of efficient production processes were actively explore to improve resource recovery and get efficiency purpose.
