Abstract: In order to improve mine design efficiency and reduce the designer's drawing workload. Based on the VRMine software platform, visual studio software was used as a development tool to study the parameterized design of tunnel section. The main research contents include: the main design content of the parameterized design of the roadway section, and the code realization of the parameterized design. Based on the research, a parameterized design system for the roadway section was completed, and the system was software tested. The research results show that: based on the VRMine software, adding a parameterized design menu for the software, designing the dialog box to obtain the drawing parameters, and designing the drawing function, this method can completely realize the parametric design of the tunnel section of coal mine, and then increase the production efficiency.
