Engineering Rock Mass Classification Book2011, Engineering Rock Mass Classification Bhawani Singh, R.K. Goel Explore book Uniaxial Compressive Strength of Intact Rock Material (qc) The strength of the intact rock material should be obtained from rock cores in accordance with site conditions. The rati...
Classification using Set 3 The jointing representing Set 3 has identical mechanical characteristics to Set 2, and so has a rating value of 21, giving an overall RMR value of 56 to 59 and a classification of ‘fair rock’. The orientation rating adjustment is now –5 (the strike is perpendi...
In underground engineering, understanding rock strength parameters is fundamental for rock classification and evaluation, significantly influencing the design and optimization of support systems. Present research emphasizes real-time assessment methods for rock conditions during drilling operations. Employing the ...
twenty criteria were compared with the judgment results of this classification standard. The results show that the judgment results of the criterion based on residual elastic energy (REE) index are completely consistent with the actual rockburst proneness, and the other criteria have some inconsistent ...

Salt rock as a soft rock shows obvious creep characteristics under a constant stress [1,2,3,4,5,6]. For creep characteristics, Tassieri et al. [7] proposed the Fourier transform method, which can well describe the creep characteristics of complex material, especially the linear complex materi...
Classification of a rock as a carbonatite on a simple modal basis as one containing more than 50 vol% carbonate is not satisfactory from a genetic viewpoint as rocks of different genetic lineages are given the same name (Mitchell, 2005; Mitchell and Bergman, 1991). Kimberlites do not occur ...
