摘　　要：准确认识回采巷道的矿压显现规律及其稳定性特征是对其进行有效控制的前提,而围岩的结构特征是回采巷道围岩大变形特征的决定性因素。本文讨论不同环境下回采巷道围岩结构特征并建立其力学模型,然后通过变形元件组合模型来模拟材料的变形特性,从而得出回采巷道围岩随时间推移变形的理论支持。Accurate comprehension of the coal pressure appearance rule and stability features is the effective control prerequisite for roadway, and the decisive factor of roadway surrounding rock large deformation is structure character. The mechanics model was established under different environment conditions in order to simulate the material deformation characters with different mechanics deformation elements combination. Therefore, the theory of surrounding rock deformation with the lapse of time was obtained.
