Abstract: 3D modeling technology is widely used in various fields.In the mining industry, the three-dimensional modeling of mining methods is the basis for mine digitalization.A well-compatible 3D model of mining methods can meet many requirements such as teaching demonstrations, 3D simulation scenarios, and physical model output.The development of modeling technology in the industrial field is relatively complete.Modeling techniques in the mining industry, such as complex geological bodies, have been studied by scholars, but the three-dimensional modeling of complete mining methods lacks a systematic approach.This paper proposes the three-dimensional model reconstruction method based on three-view.The method relies on three-dimensional modeling software, based on two-dimensional drawings of engineering practice, and combines the experience of modeling in the industrial field to study the three-dimensional modeling technology of mining methods, using B-Rep model and CSG model.It enables rapid construction of three-dimensional models of mining methods.The reconstructed 3D model can meet the teaching demonstration, 3D simulation scene construction and physical model output requirements.
