Abstract:The intelligent development of coal mine is the general trend of the future development of coal industry. 3D geological modeling and visualization technology promote the management and sharing of geological data and information. It is widely used and of great significance in the coal industry. 3D geological modeling and visualization technology can provide fine guidance for transparent exploration of geological bodies, metallogenic prediction of coal mines, reserve estimation, etc. Ensuring the scientificity of coal mining, ventilation system design and intelligent mining, intuitive disaster and accident inversion, surface environment monitoring and intelligent production management and control, reducing the risk of exploration and mining, and greatly improving the efficiency of coal development. This paper summarizes the application status of three-dimensional geological modeling and visualization technology in coal mines, summarizes its research direction in the mineral field and the use of relevant software, introduces the acquisition, processing and modeling technology of geological data and roadway data, as well as the specific situation in various application fields. Finally, combined with the development trend of accurate and intelligent coal mining, a view of the specific problems of 3D geological modeling technology in helping the intelligent development of coal mine, this paper puts forward some thoughts and understanding.
