Study on visual classification for protected objects under mining influence

The prediction system of damage grade can direct the works of identification of mining damage, environmental protection and land reclamation, etc. It is helpful to realize the sustainable development of mining areas. This system is based on the grid data of mining subsidence prediction, comprehensive analyze different combinations of the value of ground movement and deformation, realize the visual classification and quantitative analysis of different kinds of protected objects. Illustrated by the example of damage prediction of building with brick-concrete structure, introduce the theory and using method of this system, and calculate the size of damage areas of predicted ranges and surface features' ranges. The research method and prediction system provide a new way and new tool for mining design and identification of mining damage.
