摘要
针对神东矿区的典型浅埋煤层条件,用现场实测煤柱支承压力分布方法,分析给出了榆家梁矿、补连塔矿和大柳塔矿主采煤层回采巷道的合理煤柱宽度范围,对今后回采巷道布置、煤柱宽度以及巷道支护设计,具有工程实用价值和决策指导作用。
Combined with classically shallow coal seam, this paper gave out the reasonable coal-pillar width of mining gates of mainly mining coal seam in Yujialiang, Bulianta and Daliuta mines by observing abutment pressure distribution of coal-pillar. The research outcomes will have engineering application values and directing effect to layout of tunnels, designing of roadways' supports and coal-pillar width.
