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previous (or outdated) info •  Change monitoring: scanning the same area in different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

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.


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.
