The document provides information on the ZEB1 mobile laser scanner for mining applications. It describes the ZEB1 scanner and its workflow which includes data capture with the scanner, uploading data to a PC for processing into 3D point clouds, and downloading processed data. It then discusses the ZEB1's features for data management and various potential mining applications such as underground mine mapping, roof bolt inspection, volume calculations, clash detection, and change monitoring. Examples of ZEB1 scans in underground tunnels and of a stockpile are also shown. Best practices for using the ZEB1 in different environments are listed. Finally, a case study describing the use of ZEB1 and a nodding actuator for shaft scanning at a mine in Sweden is

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outdated) survey information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

Note the accurate roof surface and the approximate tunnel profile generated by
reducing the number of measurement points used to create the walls.

37. Case Studies-Lisheen Mine
Identical section of tunnel measured this time with ZEB1 and modelled again using 3D
Reshaper. Note this time the improved accuracy for all tunnel surfaces including roof
and walls leading to more accurate tunnel volume calculations.
