不同尺度地质构造对露天矿边坡稳定性的影响——以北衙万硐山露采区为例

Influence of Geologic Structure with Different Dimension on Strip Side Slope Stability——Taking Wandongshan Open Mining Area as Example

以云南北衙超大型金-多金属矿集区万硐山露采区为例,研究了不同尺度构造对露天矿边坡稳定性的影响,考虑不同尺度地质构造对边坡稳定性的综合影响,将露天矿边坡划分为四个工程地质分区,为边坡境界优化提供了可靠依据,对不同工程地质分区边坡分别提出了安全控制建议。研究成果可为地质构造复杂的露天矿边坡稳定性研究提供借鉴和参考。

Wandongshan open mining area for oversized gold-polymetallic ore mining agglomeration in Beiya of Yunnan was taken as an example,the effect of different dimension and structure on side slope stability of strip mine was studied;the side slope of strip mine was divided into four engineering geological subareas,it provide reliable basis to slope realm optimization,and it also make recommendations for security controls of different engineering geological subarea.Study results can provide reference and consulting to side slope stability of strip mine with complex geologic structure.
