Abstract
- The modeling of complex mine roadways, such as curved roadways, intersection roadways, and variable cross-section roadways, is the key and difficult point when building the 3D models of roadway network. Deficiencies exists in the existing method when reconstructing complex roadway networks based on traverse data, especially for the curved intersection roadways which are common in mines. This paper proposed a basic component assembly method (BCAM) for the modeling of the 3D roadway network by using the underground survey data of coal mine roadway. By applying three steps of BCAM, namely the modeling of roadway centerlines, the modeling of roadway sidelines, and the modeling of the basic component of roadway (BCR), 3D models of complex roadway network can be automatically constructed. The experimental results show that the proposed method is robust, and the modeling time increases linearly and steadily with the increase of data volume. The established 3D model of the roadway network can support various analyses on space, geometry, and mechanics for smart mines. [ABSTRACT FROM AUTHOR]
