Study Of Surface Dynamic Movement

Bian open seam movement and deformation caused by strata and surface is a complex process of change, surface subsidence caused by time and space is a nonlinear process of change. After being mined underground mineral resources, will be inside the rock to form a hollow, when the gob area expanded to a certain range, the development of rock movement to the surface,which causes changes in mine ecological environment, building (structure) was damage. In Surface deformation law of the actual research process must consider not only the size of the surface deformation and distribution of the final movement after deformation values stabilized, must also consider the development trend of ground movement and deformation over time. Bian open during ground movement and deformation of the exact expected to have important implications for the protection of the surface of the building.In this paper, Wolonghu8102coal face in the measured data obtained in the Face of the dynamic deformation of ground movement,in a comprehensive analysis of the present situation of basic research on the analysis of ground movement and deformation changes with time and space. Probability integral method based on the use of Matlab software to strike the ground movement and deformation parameters, and analyzes the movement angle and boundary angle isometric volume parameters, lead angle and a leading influence on the dynamic parameters such as distance. Focuses on the integration model based on a probability based on dynamic Knothe principle function of time is expected to determine the time on the method for determining the parameters c,to prepare the surface in Matlab software, dynamic movement and deformation prediction program, expected results on the accuracy of the analysis, while achieving face advance to different distances ground movement and deformation curve, sinking contour map, draw a three-dimensional surface plot of mobile basin, research article on the geological and mining conditions similar to mine design and surface mining construction (structures) protection have some guidance.
