Rock Characterisation
The rock characterization table opens with the right button of the mouse on any drillings under the Drillings in data catalog.
The following values are added in order to calcualte the "RMR (Rock Mass Rating)" of the rock:
The uniaxial compressive strength (σc) of the rock sample,
Rock quality value (RQD),
Core Efficiency,
Discontinuity interval,
Roughness,
Underground water conditions,
Correction Factors,
RMR Value | Rock Quality |
---|---|
0 - 20 | Very weak |
21 - 40 | Weak |
41 - 60 | Average |
61 - 80 | Good |
81 - 100 | Very Good |
