Abstract: As an important element in the process of mining today, deformation monitoring of mining subsidence has become a serious problem which can not be ignored. In order to minimize the damage caused by mining subsidence, we use the probability integration model to realize system design and implementation for Huainan mining area, in combination with professional GIS platform lrgis 3.0 for digital mine a variety of contours of movement and deformation were mapped out, intuitively and accurately reflecting the expected deformation of the region.
