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。
In this paper, the relationship between pressure bearing zone of mobile support and mining depth is clarified, and the effective load coefficient is proposed to reflect the deformation of surrounding rock of floor tunnel under dynamic pressure. Combined with the measured data of Suncun Coal Mine, The quantitative relationship between the deformation of roadway surrounding rock and the effective load coefficient provides a method for predicting the deformation of surrounding rock mass of roadway under the pressure of mobile bearing under deep mining.
