中文摘要：
为了研究地应力场、损伤对渗流场深部岩体的影响问题，从理论上分析了岩体渗流运动的基本规律，引入岩体变形过程中应力、损伤与透气性演化的耦合作用方程，建立了含岩体开挖过程固气-损伤耦合作用模型。应用该模型模拟分析了深部采动中岩体渗透性的演化规律。结果表明：在开采过程上覆岩层应力增大、变形增大，岩体垮落现象明显，并伴随着岩体渗透性迅速增大，应用该耦合模型解决实际工程和现场实际观测结果比较吻合。
英文摘要：
In order to investigate the impact on rock in deep flow field by stress field and damage, this study theoretically analyzes the characteristics of rock seepage. Therefore the study has introduced the coupling equations of rock mass deformation stress, damage and permeability, and developed a solid gaseous-damage coupling function model in deep mining. The model can be used to capture the evolution of gas permeability in coal seam at great depth through simulations. The simulation demonstrates that with the increase of stress and deformation, the rock fall increases with the dramatic increase of gas permeability. The simulated results are in good accordance with the in-situ observation results.
