The lithology information from the video borescopes
is best understood in relation to the roof stability in a
gateroad or section by creating a geologic cross section from
the data. If a more global view is needed, then a geologic
model will be more appropriate. Regardless of a cross sec-
tion or geologic model, the purpose of the data must be
clearly seen and easily interpreted by engineers. In using
the creation of cross sections, the roof should have bolt-
ing horizons so that engineers know if they will decide to
use a certain bolt length and the type of lithology that bolt
will be anchored into (see Figure 5). If a geologic model
is needed (see Figure 6), color scheme is very important
to quickly understanding the map or image. Generally, it’s
best to use cooler colors (blues and greens) for good condi-
tions and hotter colors (yellow, orange, and red) for bad
conditions. This will help mine management quickly iden-
tify the locations that need attention and help direct roof
control efforts to where they are needed.
VIDEOSCOPE IMAGE STITCHING
Borehole video stitching can be a valuable technique for
visualizing geological features in a borehole. By stitching
together multiple video frames, a stitched view of the bore-
hole can be created, allowing for a comprehensive visualiza-
tion of the geological formations and structures.
