Visual simulation of surface subsidence at goaf area in coal mine

Using MATLAB simulation technology,this paper has developed a prediction model on goaf surface subsidence with the integration of dynamic time function and probability integral method based on coal seam geological conditions,rock movement observation parameters and surface subsidence data.It simulates and analyzes the surface subsidence caused by coal mining operations,and achieves the surface subsidence visualization.The results show the method can reflect the dynamic characteristics of surface movement.The system realizes the accurate analysis and calculation on the surface dynamic subsidence caused by coal mining,and can draw intuitively and precisely the graphics of surface deformation.It provides an interactive 3d simulation platform for formulating a prevention and control plan for surface subsidence at goaf area in a coal mine.
