Three Dimensional Mapping of Ground Deformation Disasters Caused by Underground Coal Mining

Abstract:

The ground subsidence and deformations caused by underground mining not only affect people’s life tremendously, but also ruin the local eco-environment. These phenomenons (disasters) should be controlled and rehabilitated. For this purpose, in this paper, the characteristic and values of surface subsidence, deformation and movements were evaluated and calculated using some kinds of technological theories and methodology such as probability integral method and so on. Based on the Google Earth image and digital relief maps as well as the predicted results and data, several types of 3D thematic maps of mining subsidence and deformation were designed and mapped in order to carry on the land reclamation or rehabilitation in the mining subsidence and deformation areas. The research results can be fitted well with the reality of surface subsidence and deformations.
