Research And Apply Of On Mine Mining Subsidence Visualization Expect System

Underground coal mining state of equilibrium so that the impact of stress around the area of the original rock damage, stress redistribution, causing overlying rock and surface mining occurred caving, breaking and bending movement and deformation of the surface environment, buildings, water, production and living facilities such as railways and cause varying degrees of impact and destruction, threatening the lives and property of the mining area residents. Therefore, mining subsidence areas of mining engineering has long been expected to continue in-depth study of the important technical problems.Based on the theory papers coal mining, mining subsidence, GIS applications, database technology and software development technology, based on surface movement and deformation prediction probability integration method models and algorithms to achieve a rectangular or irregular shapes in different stope mining conditions under the main section and any point in the whole basin sink deep mined accurately calculate expected values; Using the technology of graphics processing technology and Arc GIS Engine components, with the ground movement and deformation prediction results as the basis, achieve two-dimensional, three-dimensional analysis of subsidence basin, which shows mine mining subsidence Visualization expect.Following 9103mining work face under coal mine village as an example, the application shows that system has high calculation precision, the function, the composition can meet the actual needs, for three under mining safety evaluation of surface subsidence, damage degree evaluation and management provide a scientific basis, and has important theoretical significance and application value.
