Abstract
The laboratory tests for Carboniferous rocks: claystones, mudstones, sandstones and coals are presented in the paper. The modulus value distributions for the recommended methodology were compared using statistical analysis. The typical range of the elastic linear deformability for the chosen rock types was determined. Thus the evaluation of the best Young modulus determination method was performed. Tangent Young modulus was recommended as the guiding one, studied with the range of 25-75% of ultimate stress. 503 rock samples have been investigated for this analysis.
