Abstract: The existing three-dimensional visualisation of mining subsidence cannot fully convey the original landscape in the mining area. By using GIS and coupling the predicted result of subsidence in different mining stages with the original elevation data, a dynamic visualisation of mining process is approached, which could reflect geomorphologic features clearly. Furthermore, it visually shows the variation and the characterisation of the surface subsidence, according to which one can analyse and evaluate the degree of mining subsidence damage. The generated information, such as slope, aspect, stagnant water area and the amount of settlement volume calculation, could provide technical support for reclamation work while mining is in process.

Keywords: GIS; mining subsidence; geomorphology; data coupling; geographic information systems; dynamic visualisation; geomorphologic features; surface subsidence; subsidence damage; reclamation work; China.
