When developing mineral resources, the safety and reliability of construction should be fully improved to ensure the efficiency of the whole construction. According to the actual situation of mine production, most of them are located in areas with complex terrain, which will also impose certain restrictions on safety production. Therefore, in order to further promote the development of Chinas mineral resources, the management department should fully combine the rules and regulations to implement the prevention and control of mine geological disasters and the protection of geological environment, which laying the foundation for the improvement of mine production efficiency.展开更多

This paper discusses the survey and design methods of geological disasters around the hydraulic structures. Starting from the causes of two landslide geological disasters in our city and the corresponding survey and design work, the paper further analyzes the difficulties encountered in the survey of landslide geological disasters, and finally puts forward reliable survey results and reasonable design suggestions.展开更多

Based on landslides and other geo-hazard survey data,using improved B-REP（boundary representa-tion）entity data structure （two-body 3D data structure）, we set up 3D solid models for each hazardous bodies in each hazardous geological maps. Then we integrate the two types of 3D models with different scales from area to point, which are the regional geo-hazard 3D model and the solid models of each disaster body, in order to provide a visual processing and analysis plat-form for danger partition, stability evaluation, disaster prevention and control, early warning and command.展开更多
