To solve the problems of large subjectivity, empirical, time-consuming, laborious and low efficiency of manual interaction in the design of open-pit mine slope road, a parametric three-dimensional design method of open-pit mine slope road is proposed. The general idea is: combining with the requirements of open-pit mine slope road design parameters, using parametric slope road design ideas to construct a mathematical model for parametric three-dimensional design of open-pit mine slope road. The research results were developed and realized in the digital mining software platform, and the generated road parametric 3D design model was used for an open-pit mine slope road design. The experimental study shows that the average time for completing the design of a single open-pit mine slope road is 3 h for manual interaction, and 5 min for parametric 3D design method, and the proposed parametric 3D design method of the open-pit mine slope road greatly reduces the workload of the design technicians, and accommodates the rapid automatic updating after the design parameters change. The proposed parameterized 3D design method of open-pit mine slope road greatly reduces the workload of design technicians, adapts to the rapid automatic update after the change of design parameters, and greatly improves the rationality of the design results.
