Mining Subsidence Prediction And Analysis System Based On MAPGIS

MAPGIS is a software system which set of graphics, images, geology, geography, remote sensing, mapping, computer science and which is a spatial information set of digital mapping, database management and spatial analysis and which also.is a advanced tools to conduct modern management and decision-making. And it is a very good software to study the ground deformation and movement caused by Mining Subsidence and defending.Mine production in our country, the coal under "building, water body and railway" so capacity 14 billion tons above that which is always important study for coal enterprise. In order to provide visual methods of calculation, measures of analysis, support for technologies for the study of the feasibility of mining under the "building, water body and railway", and timely predict the dynamic changes of the ground subsidence caused by mining. Combining with the widely usage of MAPGIS in mine factory, this paper has studied and developed a "Mining Subsidence Prediction and Analysis System based on MAPGIS".The system of mining subsidence prediction and analysis, which is developed on the platform of Visual C++ 6.0, using API function of MAPGIS secondary development tool, and Combined with Probability integration method which is a changes of the ground subsidence method for More mature and most widely used in our country. To achieve the visual for any shape working face subsidence prediction and analysis,That drawing the surface deformation profile moving line graph, contour map and visualization of three-dimensional map,thereby accurate prediction results and Intuitive visualization analysis to provide decision-making basis for users.At the same time analysis the possible problems of this system and describe development prospects in this field.
