With 3D spatial
information, geologists
would be able to study
more insight into resource
models and might be able
to identify residual
resources. This is especially
valuable for precious metal
deposits.

Case 3 Safety and volume inspections
Sections 470 and 495
Nine sub-sectional scans
Total time: 3 hrs

Volume inspection
Using wireframe
model to obtain total
volume of mined. It is
more accurate and
more fair。

Mapping raises
The raise at #19.5b line
is too close to the floor
of #495 level which
implies that there are
roof collapse hazards to
#470 level.

Inspection
At #470 Level, REVO data are
very close with total station data
for main galleries, but not very
close to access tunnels to
stopes, which were mainly
measured using compasses and
tape measures.

Summaries
REVO, as a new surveying tool, offers very fast and efficient 3D mapping for
underground mines.
It is especially suitable for complex 3D spaces, shafts, raises, ore passes and their
combinations.
It is very easy to use and can be operated by one person.
It offers high density of point clouds which reflects underground spaces in details.
Fast built 3D models could be read directly by most mining design which facilitate
mine design and management.

Summaries (Cont.)
It could be used in daily operation for volume inspection, if it is over- or under-
mined for fair auditing.
It could be used to check if there are safety issues.
Data could be used for optimizing resource models, calculating volume of cavities
for backfill design.
Looking forward to seeing a long range REVO for thorough mapping of large
cavities.
