Safety Evaluation on Slope of Saindak Open-pit Mine

Abstract28 indexes were chosen from 5 aspects (rock quality of slope, slope morphology, human factor, safe management of slope and other factor), and safe index system of rock slope of open-pit mine was established. Based on comprehensive fuzzy evaluation, weights of all indicators were determined through adopting analytical hierarchy process and Matlab program. Through adopting comprehensive fuzzy evaluation, safe index system was compounded and fuzzy evaluating model was established, and then comprehensive fuzzy evaluation was carried out against specific situation of Saindak open-pit mine. Evaluating result is that rock slope of Saindak open-pit mine is relatively safe, reflecting actual situation, which indicates this evaluating model is reasonable and reliable
