摘要
露天矿山开采产生的高陡边坡,在生产乃至闭坑后,往往造成崩塌地质灾害隐患,本文依据按结构类型(或结构面与边坡的关系)提出了逆向岩层和顺向岩层两种分类,并结合赤平投影图对边坡稳定性及崩塌的形成机理,提出6种边坡崩塌防治措施。
The high and steep slope produced by open-pit mining often causes potential collapse geological hazards after production and even pit closure.According to the structural type(or the relationship between structural plane and slope),this paper puts forward two classification of reverse rock stratum and consequent rock stratum,and combines with stereographic projection diagram to analyze the slope stability and collapse formation mechanism,and puts forward 6 kinds of slope collapse prevention measures.
