Slope stability of open-pit mine based on critical sliding field technology

In this paper,the critical sliding field technology was used to search for and determine the most dangerous landslide location,and then four kinds of slope stability evaluation methods including Ordinary,Bishop,Janbu,Morgenstern-Price were used to analyze the stability of the slope.Application of the above method analyzed the stability of the existing quartz stone open-pit mine slope.In the premise of ensuring the stability of the open-pit mine slope and receiving maximum production of quartz stone,the above methods was used to obtain the optimum slope angle of open-pit mine slope and determine the final mining scheme.
