The GSI index for the intact rock mass layers (beyond the main mining influence) was determined for eleven regions of Polish mines using classical forms of GSI rock mass classification where the value of GSI is similar to the values presented by Hoek (Figs. 4 and 5, dotted lines, area marked with number 1).

Early estimates of GSI were derived from the Rock Mass Rating(RMR)parameter(Bieniawski1984)ortheQ-system (Barton 1999). Hoek (1997) modified the H–B criterion by substituting GSI for RMR, which led to strong debate worldwide (Cai et al. 2004; Singh and Tamrakar 2013) used multi-parameters to …

GSI correlation for the RMR adjusted by Santos et al. (2012) for W2 rock masses from the Tamanduá mine. The division of the classification by weathering grade proved to be extremely effective, since it resulted in a coefficient of determination of 99.8%, and the adjustment of the regression line in relation to the points was close to 0, which ...
