The LiDAR accurately scans underground mine development roadways, efficiently capturing massive point cloud data and rapidly extracting roadway profile information. This provides core data support for the construction of 3D roadway models. Furthermore, the sensor can work in coordination with the tunneling guidance system, outputting high-precision roadway geometry data in real time to assist in the dynamic adjustment of excavation parameters. By replacing traditional, less efficient survey methods, it not only ensures operational safety but also provides reliable data assurance for improving roadway contour quality and advancing intelligent mine monitoring.
