Features of surface dynamic movement and deformation caused by high intensity mining under shallow depth

摘要：

　　The severity rate of dynamic movement and deformation decides the surface damage shape directly.In order to grasp laws of surface dynamic movement and deformation caused by high intensity mining under shallow depth, based on the observation data of the surface movement observation station in Shendong mine area, relevance dynamic parameters and features of the surface dynamic movement and deformation are clarified.The results are, in the condition of high intensity mining under shallow depth, the process of surface subsidence is exceptional fierce, the surface movement and deformation is more concentrated,and the subsidence basement is formed rapidly.In the process of surface movement duration, 95.3% the total subsidence occurs in active phase, the coefficient of the surface subsidence maximum velocity k is 1.73, the maximum of subsidence velocity reaches to 700.5mm/d, fore influence distance and angle is 82m and 57.8°respectively, lagging distance and angle of maximum subsidence velocity is 57m and 66.3° respectively.
