Stability Evaluation And Treatment Of A Mine Slope In Hubei Province

In order to find out the stability conditions and characteristics of the waste field slope,and to understand why the slope of the waste field occurs instability,based on a lot of relevant domestic and foreign research data,this article is based on some existing waste field sites.Slope stability prevention measures and engineering;combined with actual cases and field data confirmation and survey.Based on these data and information,the slope force condition of the waste soil site is analyzed and comprehensively understood,the mechanical parameters of the rock and soil of the waste soil site are determined,and these data are matched with the actual situation.In order to analyze the causes of the deformation and destruction of the slope of the waste soil field,it is necessary to analyze the forces on the slope of the waste soil field and evaluate the stability.So for this analysis and evaluation this article was taken,so for this analysis and evaluation this paper adopted the balance method and laboratory model simulation calculation method to analyze the numerical value of the relationship between the slope of the waste soil field may be subjected to daily forces.This article mainly uses the limit equilibrium method to analyze the slope of the waste soil field.According to the results,it can be known that the slope of the waste soil plant is in a critical state of instability due to the saturated condition of the soil.The data show that when the soil inside the dregs body piled up on the waste field slope is deformed,the slope condition is unstable;while in the natural state,the waste field slope is basically stable,but this stable condition will be caused by The saturated state of the soil is broken.When the maximum displacement of the soil exceeds 45 cm,the slope of the waste field will collapse due to deformation.When importing the experimental data to the on-site exploration record form,it can be found that the laboratory data is basically consistent with the data obtained on-site.Based on the above analysis results and laboratory model experiments,combined with actual data,two different slope instability management schemes were obtained.The first method is to reduce the load and rational slope protection and support structure plus ecological grass planting.Perform slope maintenance,andfinally implement field monitoring through monitoring and early warning;the second option is to reshape the overall slope surface according to the degree of slope instability,the protective structure is anti-slide pile enclosure,and finally slope greening And monitoring early warning.Based on other comprehensive factors,and taking economy and environment as consideration technologies,through analysis,the most suitable wasteland slope stability maintenance plan for a mining project in Hubei was selected.Based on comparison and reference data,it was found that plan 1was the most suitable for this case project.Implementation.Through the practice of this scheme,it can be known that the slope stability protection based on scheme 1 can effectively solve the hidden danger of the slope of the mine waste soil plant to prevent accidents,and can also restore the surrounding ecology of the waste soil plant through ecological planting.The environment has both beautified and reinforced the slope.
