Abstract: Maptek I-Site SR3 three-dimensional laser scanner is introduced into Jinchuan No.2 mining area, which is applied to the acceptance work of mining engineering. Relying on its excellent measurement accuracy, work efficiency and non-contact measurement, it greatly reduces the intensity of measurement and safety hazards while improving the quality and efficiency of engineering acceptance. The Point Studio modeling software supported by the scanner can quickly build a three-dimensional solid model and accurately calculate the amount of mining work. This technology lays a foundation for creating green mines and digital mines.

Key words: 3D laser scanning, 3D solid modeling, work amount, mine survey
