This paper presents a methodology for a semi-quantitative assessment, developed for a large mining project, supporting a strategy for selecting rockfall risk mitigation measures via cost-benefit analysis. This is achieved by treating rockfall...

In addition to the need for analysts to better assess intrinsic variability in rock material strength ( UCS i ), correct evaluation of rockmass behaviour depends on accurate definition of the two other key H - B criterion parameters ( m i and GSI ).
