Abstract: Aiming at the problems of large design amount and complex calculation amount in traditional coal mine design, by analyzing the forward design requirements of coal mine engineering, the complex mining system in coal mine is presented in an intuitive and three-dimensional way, and the secondary development idea based on Revit platform is proposed. The secondary development of Revit is carried out to expand the application function from the platform and improve the adaptability of Revit platform in BIM system to coal mine engineering design industry. Through the example verification, the main components of the underground coal mine in Guizhou Qianxin Coal Mine are developed and designed, and the corresponding attribute parameters are given to the model components to complete the automatic statistics of the engineering quantity. Combined with other BIM software, the underground three-dimensional digital model is designed, which improves the design quality and drawing efficiency, and improves the linkage between data and images. It provides a reference for the application of BIM technology in the forward design of coal mine engineering, and looks forward to the application prospect of this technology, in order to further promote the process of digital mine construction.
