N2 - This paper summarizes some results of an applied block theory research conducted at Berkeley over the last three years. The validity of the critical-key-block concept is tested here using block mould statistics sampled from side walls of two tunnels, the raw data of which are shown. The predictive capabilities of the three block-failure-likelihood parameters are tested by correlation with the block mould sample population, and a modification is introduced. A possible method to integrate a block motion criteria in empirical rock mass classification systems is proposed.
