Quality Analysis and Stability Study of Stope Slope Rock Mass in an Open-pit Mine
With the increasing scale and depth of mining and stripping,the influence of local slope of open-pit mining is becoming more and more prominent.Taking an open-pit mine with goaf inside a partial slope as an example,the rock mass quality analysis and slope stability research are carried out through field investigation,numerical simulation and theoretical analysis.The results show that RQD method and BQ meth-od are consistent in grading the rock mass of the open-pit slope,and the rock mass quality grade of the open-pit slope is mainly Ⅲ.The mined-out area distributed inside the open-pit slope has little influence on the sta-bility of the slope,and the overall stability of the slope is good.The numerical simulation conclusion provides a favorable basis for the follow-up safe and stable production of the open-pit mining area.
