Abstract: Aiming at the problem that the existing roadway design lacks scientific, effective and unified design basis and relies on the data analysis and practical experience of engineering and technical personnel, which leads to poor roadway design effect, this paper deeply integrates roadway design with transparent geology and comprehensively uses computer programming and artificial intelligence technology. A set of intelligent roadway design system based on accurate 3D geological model is studied. Based on the established accurate and transparent geological three-dimensional model, the system realizes the two-dimensional layout design of the roadway. Through the calculation of the 3D geological model, the pre-mass profile of the roadway is automatically generated, the floor elevation of the roadway is automatically identified under different excavation methods and over construction conditions, and the disaster avoidance chamber is automatically added at a fixed distance. According to the mechanics and topological relation of roadway surrounding rock, the support scheme of roadway is calculated automatically. The optimal roadway support scheme is obtained by integrating with the support results of the roadway support expert system obtained through machine learning, and the differential support of roadway "one roadway, one policy" is realized, which saves the support cost and improves the support efficiency. According to the observation results of the surrounding rock of the roadway, the sketch of the roadway is generated to realize the real-time closed-loop update of the 3D geological model, roadway elevation and roadway support, and constantly improve the accuracy of roadway design.
