The document describes the ZEB1 mobile laser scanner for mining applications. It can be used for tasks like underground mine mapping, roof support bolt inspection, accurate volume calculations, clash detection, and change monitoring. The ZEB1 captures 3D scan data that is uploaded and processed into a point cloud and 3D model. Examples show it being used to scan underground tunnels, mine shafts, and stockpiles. When combined with the ZebRA remote actuator, it can perform autonomous scans. Case studies demonstrate its use at a coal mine and copper mine for applications like tunnel profiling and comparison to total station surveys.

- 11. Mining Applications • Underground Mine Mapping: Mapping areas without previous (or outdated) survey information • Precise Offsetting - Rapidly scan a big area for measuring your offsets • Roof support bolts inspection - Inspect the layout and locations of your underground roof supporting bolts • Accurate monthly mining advance volume calculations - By creating a triangulated solid mesh from the point cloud generated one can quickly calculate your monthly advance volumes
- 12. Mining Applications (cont.) • Clash detection - By utilizing the 3D model of a tunnel section one can determine in a new haulage truck or infrastructure will fit into or through certain areas in the mine • Overbreak & Underbreak analysis - Do proper evaluation of your tunneling by the drill and blast method • Change monitoring: scanning the same area in different epochs to detect and quantify changes • As-built vs. Mine plans - Compare proposed mine plans with actual underground scan data to accurately understand the progress and efficiency of your mining operation.
- 13. Mining Applications (cont.) • Restricted area mapping: use of the ZEB1 along a remote vehicle to safely scan in areas of difficult access (ZEB+ZEBRA combo) • Incident recording: use to record all details surrounding an incident scene • Advance tracking: to quantify advances in underground tunnels • Volume calculation: measure stockpile volumes and other materials
