摘要
本文阐明了移动支承压力影响区与采深的关系，提出了用有效载荷系数来反映动压作用下底板巷道围岩变形量的大小，结合孙村煤矿实测资料，总结出在跨采期间，底板巷道围岩变形量与有效载荷系数之间的定量关系，为深井开采移动支承压力作用下，底板巷道围岩变形量预测预报提供了一种方法。
his paper clarifled the relation between moving abutment pressure zone and mining depth,suggested using active load coefficient to reflect the measurements of surrounding rock deformation of floor roadway under the pressure of dynamic pressure. And on the basis of ob-serving information in Suncun Colliery, the quantitative relation between the measurements of surrounding rock deformation of floor roadway in the period of working across over roadway and active load Coefficient was summed up, then it offered a method for estimating measurements of surrounding rock deformation of floor roadway under the pressure of moving abutment pressure in deep shaft.
