摘要
针对抚顺东露天矿现场生产局部采用并段方式,由此增加台阶高度的实际情况;分析了并段后剥岩量的变化、对下部富矿采区露出的影响、台阶高度变化后对露天矿剥岩费用的影响关系。结果表明:采用台阶并段的方法来增加台阶高度可以减少剥岩量,并加快下部采区露出,增加经济效益。
Aiming at the actual situation of Fushun East Open-pit Mine,locally using the method of merging sections to increase the step height,the article analyzes the change of rock stripping amount after merging sections,the influence on the exposure of the lower rich ore mining area,and the influence relationship between the change of step height and the rock stripping cost of open-pit mine.The results show that increasing the step height by bench merging can reduce the amount of rock stripping,speed up the exposure of the lower mining area,and increase economic benefits.
