泥岩风化影响下露天矿采场陡帮顺倾边坡稳定性分析

Steep and layered rocky slope stability analysis of open pit mining stope effected by mudstone weathering

煤层剥离后煤层底板泥岩易风化,强度明显降低,对陡帮顺倾边坡稳定性影响很大,非常有必要进行此方面的研究。以某露天矿采场南帮典型剖面为例,进行了露天矿开采过程中边坡的稳定性分析,得到了受泥岩风化影响的露天矿边坡稳定性特征,进行了露天矿采场陡帮顺倾边坡稳定性评价,对露天矿安全开采及陡帮顺倾边坡治理具有重要的指导意义。

The intensity of mudstone reduced after seam floor weathering, has a great influence on the steep and layered rocky slope stability, it is necessary to study in this regard. An open-pit mining field south slope typical sections, for example, the slope stability in open pit mining process is carried out, open pit slope stability characteristics affected by mudstone weathering are received, and the open pit mining field steep and layered rocky slope stability is evaluated. The results provide an important guiding significance to the mining of open pit mine safety and the steep slope along dump slope governance
