A risk-based methodology for establishing landslide exclusion zones in operating open pit mines

摘要: Abstract The high consequences of recent large open pit slope failures have increased industry and regulatory interest in establishing exclusion zones beneath an impending wall failure. This paper proposes a methodology to delineate zone for focus this is framework the management life loss risk most exposed individual. probability landslide occurring resulting being very or extremely rapid are described paper. Set probabilistic , empirical runout analysis tools useful estimating spatial impact throughout zones. Runout exceedance charts calibrated dataset provided. temporal that individual present cannot be evacuated also described. mapped across floor by dividing it into square grid cells calculating death each cell. can colour coded indicate specific exposure ranges relative set. A conceptual case study used illustrate proposed methods.
