摘要为评价开采活动对断层的扰动效应，引入构造地震断层库仑破裂应力的概念，建立开采活动引起的断层面库仑扰动应力变化动态模型，提出开采对断层扰动效应的特征判据，即基于库仑扰动应力变化的断层扰动破坏应力判据、面积判据和梯度判据。开采引起的库仑扰动应力越大，变化梯度越高，涉及的空间范围越大，则断层活化的可能性或者孕育冲击性动力灾害的危险性就越大。据此理论结合数值模拟综合分析鲍店矿开采活动对断层的扰动效应，分析结果与矿区实际情况基本吻合。

Abstract：In order to evaluate the fault disturbance effect caused by exploitation，the concept of coulomb failure stress of tectonic earthquake fault has been introduce，the dynamic model of coulomb disturbance stress changes in fault plane caused by mining disturbance is established，and characteristics criterion of disturbance effect caused by exploitation is advanced. The characteristics criterion includes stress criterion，area criterion and gradient criterion expressed by coulomb stress changes. The higher the level and gradient of coulomb disturbance stress and the greater the distribution range，the bigger the potential risk of triggering dynamic disaster. On the basis of this theory combining with numerical simulation technology，the fault disturbance effect during coal exploitation in Baodian mine is analyzed，the results of which is roughly tallying with the actual situation

Key words： mining engineering near fault exploitation disturbance effect Coulomb disturbance stress characteristics criterion
