Deformation Monitoring of Surrounding Rock in Mine Excavation Based on Laser Scanning
The three-dimensional laser scanning technology with high precision and convenient use is introduced to monitor the deformation of surrounding rock in the process of mine excavation.The point cloud data obtained by three-dimensional laser scanning is transformed into three-dimensional model and Auto-CAD plane graphics to compare the changes of roadway section.Three-dimensional laser scanning is carried out on the excavation process of the unloading station in the-620 m section of Luohe Iron Mine to monitor and analyze the deformation of surrounding rock during excavation.The analysis results show that the three-dimensional laser scanning technology can effectively monitor the state and deformation of surrounding rock,and has the advantages of non-contact measurement,high data sampling rate,high resolution and high precision,which provides strong technical support for mine safety production.
