Utilization of statistical analysis to identify influential slope parameters associated with rockfall at openpit mines

Bourgeois, Josef; Warren, Sean; Armstrong, Jorge

ABSTRACT:

Researchers at the Spokane Mining Research Division (SMRD) of the U.S. National Institute for Occupational Safety and Health (NIOSH) investigated the influence of slope height, slope angle, slope material and rock size for both rigid-body and lump-mass models in a two-dimensional statistical analysis program. Based on a literature search and industry input, specific ranges common to that of an openpit mining environment were chosen for each of the input parameters to determine 90 percent rock runout distance as well as their sensitivity to change. Data collected from this numerical analysis and simulation will be compared to empirical rockfall data gathered through the duration of the Highwall Safety project being conducted by NIOSH from 2022 to 2026.
