SRK Kazakhstan ›South America: Chuquicamata pit closure
SRK assisted in providing information for decisions on the best slope steepening alternative for closure of the pit. The methodology included three main tasks: Evaluation of the probability of failure (PF) representative of the stability conditions of pit slopes; Evaluation of economic losses derived from impact on production and costs; and generation of risk maps to compare the four closure alternatives. The results provided valuable information for decisions on the closure plan in accordance with the mine’s reference criteria for economic risk.
