These products are often used to develop a Revised 29th June 2022 database of smart mines which in terms can be used in the management of Accepted 31st Oct. 2022 production in underground coal mines. Unmanned aerial vehicle UAV Keywords and terrestrial laser scanning TLS technologies are known as the two 3D model main technologies that quickly and accurately collect 3D point cloud PC Point Cloud data. This article presents the integration of a 3D point cloud produced from UAV photos and TLS to build a detailed 3D model for the ground SCN plant at the level of 35 m in the Nui Beo underground coal mine. To collect TLS data a DJI Phantom 4 Advanced drone was used to take photos in three UAV. modes a shot angle of 900 a 3D grid with a 450 angle and a circular flight orbit with 450 and 600 shooting angles. A Faro Focus3D X130 laser scanner was used for scanning the mine shaft s tower to fill the missing point cloud of the UAV. The PC established by both methods was evaluated for accuracy based on the control points measured by a Leica TS09 total station which was merged by the Iterative Closest Point ICP algorithm. The integrated PC met the accuracy requirement of establishing a 3D model of the study area with the level of detail 3 in the CityGML standard. Copyright 2022 Hanoi University of Mining and Geology.
