Development and application of intelligent analysis system of ground disaster information in mining area based on big data

In order to promote the information management of geological disasters and the scientific evaluation of geographical impact in mining areas, and realize the coordinated development of ecological environment protection and governance after resource development, this paper combines with the current situation of geological disasters in mining areas in Shanxi province, aiming at the needs of geological disaster data information construction, intelligent query and geographical impact assessment in mining areas, the combination of geological disaster information management and geological disaster risk assessment ensures the real-time update of information.Based on WebGIS development platform, distributed database and B/S architecture are adopted to realize the online operation of the system, and the functions of query and retrieval, statistical analysis, core density analysis and geological disaster risk analysis of geological disaster information in mining area are designed and developed.The results show that the terrain, vegetation coverage and human activities are the important factors affecting the development of geological disasters, but the influence on the development of different geological disasters is different; as far as the risk of disaster point is concerned, collapse disaster is the main geological disaster faced by Shanxi province.Although the number of ground fissure disaster is the largest and the most widely distributed, its average risk is low.
