Research on transparency of hidden disaster causing factors in coal mines based on 3D geological modeling technology

Hidden disaster causing factor is the key issue that restricts the construction of intelligent coal mining. The 3D geological modeling is the main technical means to achieve transparency of hidden disaster causing factors. At present, the 3D geological modeling technology of coal mines mainly relies on geometric modeling and attribute modeling as a supplement, lacking disaster attribute modeling for hidden disaster causing factors. In order to solve the above problems, taking a coal mine in northern Shaanxi as the research object, the 3D geological modeling is conducted on hidden disaster causing factors such as coal seam thickness, roof and floor structural undulations, waterlogged areas, and shallow coal seam topography. Firstly, the digitization of geological data, geophysical exploration, drilling and other achievements are completed. The coal mine geological database is established. Secondly, the DepthInsight modeling software is used to carry out modeling work from two scales: the entire mine and the wo
