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.

The raise at #19.5b line

is too close to the floor

of #495 level which

implies that there are

roof collapse hazards to

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.
