Status and development trend of 3D laser scanning technology in the mining field

摘要

3D laser scanning technology to a complete and high-precision reconstruction scan physical and quick access to the raw survey data, the most important feature is high precision, fast speed, approaching the prototype, has been widely used in various fields of mapping and other. In this paper, based on the three-dimensional laser scanner application elaborated on the basis of the domestic situation, and focuses on the application in the mining field, including: 3D reconstruction and measurement of open pit, head-frame deformation monitoring, mining subsidence monitoring, construction land reclamation regulatory, difficult arrival region survey of coal gangue dump, landslide monitoring, deformation monitoring of underground mined area. Finally, the five aspects of the future development trend were forecasted and analyzed.
