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 ValueRock Quality
0 - 20Very weak
21 - 40Weak
41 - 60Average
61 - 80Good
81 - 100Very Good
