Regularity Of Movement And Deformation Of The Surface Dynamics

With the wide range of many mechanical coal mining, due to coal mine and the arrival of bad environment and the sharp social contradictions, impact area residents of daily life and production activities bring huge, followed by compensation for residents of coal mine has also become a huge burden. When the underground coal resources mining and underground rock mass will therefore have a space, goaf reach of, strata movement diffusion to the surface, motion and changes in the surface, causing buildings collapsed or crack in the vicinity of the residents in the mining area environment poses a serious threat.In this paper,Qingdong Coal Face 726 as an engineering example, describes the basic principles of mining subsidence prediction, based on the probability integration method introduced subsidence prediction method parameters computed by combining Blotzmann function of probability integration method be amended to strike the surface movement and deformation prediction parameters. Use is expected to strike the best fit parameters,combined Knothe time function method,to determine the time on the range parameter c, the preparation of the mining subsidence dynamic visual file. Using MATLAB software numerical processing and graphics rendering capabilities, to achieve the exploitation of visualization. For face advance when ground movement and deformation laws to different distances for analysis. Mining Subsidence Visualization includes a main section Mainland table movement and deformation curves and contour maps of surface subsidence and the whole basin draw two moving parts to achieve a dynamic mining process two-dimensional and three-dimensional visualization process. Results of this study has some significance for coal production under similar geological conditions.
