Figures & Tables

Figure 1:

Visualization of the entrance to the underground track “St. Johannes” Mine in Krobica (Kobylańska, 2012).

Figure 2:

Location of the scanned 7.5-m fragment of the adit on the underground track “St. Johannes” Mine in Krobica. In the vicinity of the measurement site, there is a shaft connecting both adits (St. Leopold below and St John above).

Figure 3:

Trimble TX8 laser scanner during measurements in the St. John adit.

Figure 4:

The intensity of the laser beam reflection in the adit (the black spot is a fragment of the sidewall closer than 60 cm from the scanner).

Figure 5:

“Point cloud” visualization of a fragment of the St. John adit, displayed by the value of the reflection intensity parameter.

Figure 6:

(a–c) Generating 2D cross sections from (a) “point cloud” in CloudCompare software and (d, e) dimensioning of a selected characteristic cross section.

Figure 7:

(a, b) Creating the cross sectional geometry of the scanned fragment of the adit and (c, d) its discretization in FLAC 3D Itasca v.9.0 software, sketch option.

Figure 8:

Geometry obtained for the quasi-3D numerical model of the underground excavation in the FLAC 3D Itasca v.9.0 program.
