摘要
露天石灰石矿开采边坡受力复杂,稳定性成为关键问题,为此提出露天石灰石矿开采过程边坡安全加固技术。首先对边坡安全受力情况分析,将抗滑桩与锚索相结合,并根据受力支护结构参数,结合分级施工法,实现边坡分级钻孔注浆加固施工。实验证明,该技术在露天石灰石矿开采边坡安全系数高于传统技术,具有良好的应用前景。
The stress of open-pit limestone mining slope is complex,and the stability becomes the key problem.Therefore,the safety reinforcement technology of open-pit limestone mining slope is put forward.Firstly,the safety stress of the slope is analyzed,and the anti-slide pile is combined with the anchor cable.According to the parameters of the supporting structure,combined with the grading construction method,the grading drilling grouting reinforcement construction of the slope is realized.Experiments show that the safety factor of slope mining in open-pit limestone mine is higher than traditional technology,and has a good application prospect.
