摘要
为了研究深部软岩巷道不同岩性段变形特征并对其影响因素进行分析,以鹤煤三矿-800 m水平南翼轨道上山为研究背景,通过布点监测,研究了深部软岩巷道不同岩性段内两帮及顶底板的最大移近量与移近速度,并对其主要影响因素进行了分析。
in order to study the deformation and destruction characteristics of different lithologic section in deep soft rock tunnel and analyze the influence factors, on the basis of the orbit in the south flank of -800 m level in Hebi No.3 coal mine,through stationing and monitoring,the values of maximum approach between the two sides and the roof and floor of different lithologic section in deep soft rock tunnel and the influence factors are researched respectively.
