Development and application of 3D transparent gas geological software based on GIS

Under the general trend of intelligent construction of coal mines, it is an important technical means for accurate mining and safety production guarantee of coal mines to achieve 3D transparency of mine geology through software technology.As an important part of mine geological guarantee, gas geology must be improved from 2D map to 3D transparent visualization.Based on the comparative study of 3D GIS platforms at home and abroad, this paper designs the framework and module functions of 3D transparent gas geological software based on software engineering methods, and studies the 3D modeling methods of roadways and working faces, boreholes, coal(rock) geological bodies, gas distribution, faults and collapse columns.In order to enhance the application ability of 3D gas geology, an application tool based on geological body and voxel grid model is designed to assist observation and understanding of 3D gas geological information.Finally, a 3D transparent gas geological software is developed based on GIS platform, and the application research is carried out using the test mine data, and a good 3D gas geological modeling effect is achieved.The research show that the design and development of 3D gas geological software based on GIS is a reliable technical way to realize the transparency of mine gas geology, and can provide strong support for the intelligent construction of coal mines.
