The paper presents rock classification taking into account geological engineering. Geological classification includes eruptive, sedimentary and metamorphic rocks. Mention is made of the lack of a uniformly accepted geological engineering classification. Classifications according to M. M. Protodjakonov, who developed the scale of rock hardness (1926), and textural and structural classification according to N. Duncan, who divided rocks into five groups (1969) are presented. Classifications based on single axial compressive strength according to P. B. Attwell and I. W. Farmer (1976), classifications based on the modulus of elasticity and single axial compressive strength according to D. M. Deer and R. R. Miller (1966) are also presented. K. McGregor grouped rocks according to their behaviour during boring (1968). Z. T. Bienianwski developed a rock classification for underground work based on numerous other investigations (1970). Classification of carbonate rocks for the evaluation of slope stability according to T. Novosel based on eight parameters with in situ and laboratory measurements are also presented. E. Mandjic suggested a classification based on ten parameters for the evaluation of mining underground chambers and for the use of an efficient system of timbering (1977).
