摘　　要：某矿井田东部及南部9号煤层已经部分采空,8号煤层与9号煤层层间距为11.5 m左右,某矿8号煤层的开采面临上行开采难题,通过现场调研、实验室实验、现场钻孔窥视、理论分析计算等方法,研究得出:8号煤层采用长壁开采时,底板可能会破断失稳,8号煤层采用连采机为可行的上行开采方法。The 9th coal seam in the eastern and southern parts of a certain mining field has been partially emptied.The distance between the 8th coal seam and the 9th coal seam is about 11.5 m.The mining of the 8th coal seam in a certain mine faces difficulties in upward mining.Through on-site research,laboratory experiments,on-site drilling observation,theoretical analysis and calculation,it has been found that the bottom plate of the 8th coal seam may break and become unstable when using longwall mining.The use of continuous mining machines is a feasible upward mining method for the 8th coal seam.
