ZEB1 Work Flow (Part 2: Final Result)
Geo-‐referencing RAW scan data to control
Intersection of pole and roof is control point
Hang short pole from roof peg

Data Processing Calcula9on
Holmans Test Mine, UK Scanned in 11 minutes – Data processed in 11 minutes
Mining Applica9ons • Underground tunnel mapping: mapping areas without
previous (or outdated) info • Change monitoring: scanning the same area in different
epochs to detect and quan9fy changes • Restricted area mapping: use of the ZEB1 along a remote
vehicle to safely scan in areas of difficult access (ZEB+ZEBRA combo)
Mining Applica9ons • Incident recording: use to record all details surrounding
an incident scene • Advance tracking: to quan9fy advances in underground
tunnels • Volume calcula9on: measure stockpile volumes and
other materials • As-‐built vs As-‐designed plans

ZEB1 Users
ZEB1 Sha) Scanning Case Study at Kiruna Mine, Sweden with ÅF Consult
The Challenge:
ZEBRA Components for ShaY Scanning ZEB1 Scanning Head
ZEBRA Nodding Actuator
ZEB1 Data Logger
Winch to lower down shaY
Nodding Movement
350m deep shaY
View Down ShaY
View from Top – showing scan head trajectory
ZEB1 Survey Process
• Lower ZEB1 down shaY and raise back up. – 30 mins
• Upload for automa9c processing. – 30 mins processing
• Data available for analysis. – Immediate review of results
Case Studies-‐Lisheen Mine
ZEB1 with ZebRA mount & remote actuator for autonomous use
Case Studies-‐Lisheen Mine
Sec8on of tunnel measured with Total Sta8on and Modelled using 3DReshaper. Note the accurate roof surface and the approximate tunnel profile generated by reducing the number of measurement points used to create the walls.
Case Studies-‐Lisheen Mine
Iden8cal sec8on of tunnel measured this 8me with ZEB1 and modelled again using 3D Reshaper. Note this 8me the improved accuracy for all tunnel surfaces including roof and walls leading to more accurate tunnel volume calcula8ons.
