Abstract: In order to make up for the defects of visualization in existing mining subsidence prediction computer program，mining subsidence prediction program based on probability integration method was developed by Active X Automation technology. SURFER kernel functions were operated by VB and then surface movement and deformation contour，3-D surface map，cross section map and auto analysis were realized. Multiple mining workface and multiple coal seam of a coal mine in Shandong were shown to explain the system. The results showed that the system can meet the requirements in working，that is，it can improve mining subsidence prediction and analysis work efficiently，and also reduce the workload of programming. The specialization and automation of the mining subsidence mapping and analysis are realized.
