摘　　要：矿山工程处于构造块体中,会受到板块构造活动的影响,矿井动力灾害与板块及构造块体的活动密切联系。以板块构造学说为基础,运用地质动力区划方法确定了不同尺度和级别构造活动的特征,提出用构造凹地反差强度、地形曲率变化来评价区域地质动力环境的方法,揭示了矿井动力灾害发生的动力条件与能量基础,建立了板块运动与矿山工程实际的联系。应用结果表明,阜新矿区具备发生动力灾害的地质动力背景,已发生的冲击地压地点处于地质动力区划方法确定的动力区域影响范围内。The mining and its engineering are conducted in the tectonic blocks and easy to impact by plate tectonic activity. The mine dynamic disaster is the close contact with the activities of plates and tectonic blocks. Based on plate tectonic theory, the authors determine the tectonic activity characteristics of different scales and lev- els by geo-dynamic division method and put forward that regional geological dynamic environment can be evaluated by contrast intensity of structural cave and terrain curvature changes. It is revealed the dynamic conditions and en- ergy foundation of mine dynamic disaster and the authors established the link between plate movement and mine engineering practice. Application results show there is the geological dynamic background in Fuxin mining area, and the points where the rock burst took place are in the dynamic impact area, which is determined by geo-dynamic di- vision.
