Determination of geological strength index of jointed rock determine the GSI values of a rock mass disturbed by underground exploitation. In recent years, several authors such as Han et al. (2014), Poulsen et al. (2015) and Wang et al. (2015a) have also suggested many methods to determine the strength and deformation parameters of rock mass using GSI.
