• Rock Mechanics an introduction for the practical engineer

    Rock mechanics research in South Africa was initiated some 15 years ago in an effort to provide an understanding of the rockburst hazard which occurs in many deeplevel gold mines The effects of a typical rockburst are illustrated in Figure 1 It has been defined2 as damage to underground workings caused by the uncontrolled disruption of rock
