Abstract:

A new method for simulation technology of laneway engineering seamless excavation based on 3D geoscience modeling (3DGM) was proposed to overcome the deficiency in current research. The generalized triprism (GTP) data model was used as the basic modeling element in this method. The models of geological body were created by the method of rock pillar body partition (RPBP) modeling. The laneway engineering models were built with component method, while the corresponding triangles in sections were connected and transformed into tunnel GTP models. All the GTP models were converted into tetrahedron models based on the smallest vertex identifier (SVID). The simulation and spatial analysis of laneway engineering seamless excavation could be realized through the local hierarchical intersection (LHI) algorithm. The application case showed that the method was fast and effective, and it could meet the needs of design and spatial analysis for mine laneway engineering.
