Stability Analysis and Treatment Measures of a Mine Landslide
[Purposes]This paper aims to fully understand the formation mechanism of landslide in min-ing area,scientifically analyze and evaluate the stability of landslide,improve the effect of landslide treatment,and ensure the safety of construction and operation around the mining area.[Methods]Based on the 1∶10 000 geological disaster+risk slope fine survey demonstration project in Guizhou Province,the landslide control in a mining area of a town in Guizhou Province was taken as a practice.The mecha-nism of landslide,landslide stability and engineering countermeasures are comprehensively explored,and the characteristics of landslide cracks,surface deformation and surrounding rock are observed.The basic characteristics of the landslide and the formation mechanism of the landslide are analyzed.[Find-ings]The survey found that under the influence of rainfall,the weak surface of the landslide produced a muddy interlayer,which sharply reduced the shear strength.At the same time,the excavation was un-loaded at the leading edge of the slope,and various factors led to the aggravation of sliding deformation,which eventually led to the landslide.[Conclusions]Through the calculation of landslide stability,the stability of landslide under different working conditions is studied,and the landslide prevention and con-trol measures are put forward for the unstable area,which provides reference for the same type of land-slide treatment project.
