Abstract: This paper analyzes the shortcomings of the current 2D CAD design in the coal industry, the advantages of 3D collaborative design based on BIM technology, the characteristics of mainstream 3D and BIM software, and uses the Bentley series of software to explore the 3D collaborative design of Zhangjiamao mine. The paper combs the principles and processes of 3D collaborative design, and points out the feasibility and existing problems of 3D collaborative design in mine engineering. The related research and experience can provide reference for the application and popularization of 3D collaborative design in mine engineering.
