to displacement data can be seen on the roof and left rib.
The roof successfully displays an interpolation between
the data that is coming from the two MPBXs that were
installed on the roof. The displacement from each MPBX is
in the same threshold, resulting in a smooth singular color
without transitions, representing the risk hazard of that
area. The left rib also successfully displays the interpolation
between the data coming from the two MPBXs that were
installed on the left rib. The displacement from one MPBX
shows higher values, while the other one shows lower val-
ues, resulting in two thresholds of TARP level. This transi-
tion between TARP levels can be seen in the visualization as
the interpolation smoothly changes from one RGBA value
to another.
Nevertheless, improvements are needed for the com-
plex model of the decline. The area between the roof and
the left rib does not have a smooth transition and contains a
segment of grey color representing the absence of data. This
is due to the complexity of the triangulated mesh, caus-
ing challenges when unwrapping it onto a 2D UV map.
Further work is currently being conducted to improve the
final rendering of the visualization on the complex model.
CONCLUSIONS
Scientific visualization in 3D is capable of giving crucial
information about the safety of ground conditions, and of
aiding geotechnical analysis processes. However, most visu-
alization in the geotechnical domain comes from preexist-
ing mathematical simulations and analytical processes with
minimal representation of the current state of the rock mass
by using monitoring data. Therefore, this paper focused on
developing a basic 3D visualization of rock mass movement
following the profile of an opening at the East decline at the
SX mine.
The goal of the visualizations was to convey the direct
status of risks surrounding ground movement using TARP
levels. Even though other methods for TARP-level visual-
izations are used in the industry, an area-focused interpo-
lated visualization that represents movement over a surface
has not been applied. As seen in the results, the interpo-
lation of displacement data and representing it according
to TARP levels gives insight into the hazard levels of the
ribs and roof separately. This aids the assessment of ground
movement and gains further information. Future work will
consist of improving the visualization rendered on the com-
plex 3D model of the decline. Further work will consider
other interpolation techniques such as kriging, to have even
a further understanding of the ground movement where
the ribs and the roof will be relative to each other.
