Abstract:The precise surveying of mine tunnels is a crucial component of mining operations, yet current surveying methods lack rapid and efficient data measurement and sharing capabilities. This study introduces an adaptive slice-based volume calculation method for tunnels, leveraging portable laser scanners and capable of integration into various Simultaneous Localization and Mapping (SLAM) frameworks to meet the demands for high accuracy and real-time field surveying. Field experiments demonstrate that, compared to traditional mining measurement techniques, both volume and cross-sectional errors are maintained within 2%, with computation times kept under 200 ms. Moreover, this allows real-time viewing of the measured tunnel volume on handheld devices and facilitates rapid integration with backend mining software, effectively enhancing on-site surveying efficiency and improving data sharing capabilities between departments.
