Abstract
In order to determine the safe distance between the excavated slope of the soft rock open-pit mine stope and external dump,taking the slope of the north external dump of Huolin River No.2 Open-pit Mining Area as engineering examples,based on finite element stress-strain and finite element slope stability analysis,the article calculates the influence of external dump on stope excavated slope deformation and slope stability under different safety distances.The results show that as the safety distance between the excavated slope and the external dump increases,the deformation of external dump and excavation position is significantly reduced.The calculation determines that the safe distance between the excavated slope outside the dump is 250 m.关键词
