本文根据巷道观测站的观测结果，对岩层内部的移动变形进行了简要分析。认为：岩层内部的移动变形参数是随距采空区高度的不同而变化的；下部煤层的回采不影响冒裂带总高度以上煤层的正常开采；对巷道有破坏性影响的最基本因素是“高厚比”和巷道围岩状况。
In this paper, based on the observation results of the tunnel observation station, the deformation of the rock mass is analyzed briefly. It is considered that the deformation parameters of the rock inside the rock vary with the height of the goaf. The mining of the lower coal seam does not affect the normal mining of coal seam above the total height of the rock. The most basic factor that has a devastating impact on the roadway is “ High ratio ”and roadway rock conditions.
