摘要
针对端氏煤矿大采高综采工艺对回采工作面围岩特性的影响,分析了沿空留巷技术对围岩的变形特点,提出了选择合理巷旁支护材料的依据,在此基础上分析目前国内外所有巷旁支护材料的适用特点,最后确定高水充填材料最为适合端氏煤矿沿空留巷的应用。
According to feature of surrounding rock is affected by in the condition of large mining height in Duan shi mine, analyzed gob-side entry retaining make the distortion of surrounding rock, proposed a reasonable choice about thet reasonable material of roadside support, and analysis all the supporting materials on applicable characteristics at home and abroad, Finally, insure high water filling material is the most suitable for gob-side entry retaining in Duan shi Coal Mine.
