The Study On The Stability And Treating Of DaKouZi Landslide Of Niangniang Mountain In Henan Province

In recent years, with the increasing demand for energy, mining industry is rapidly developing,as a result, the emerging mining geological disasters.Particularly complex geological conditions in the mountains, the landslide caused by the mining.Collapse of geological disasters such as a direct threat to local people's lives and property, and economic development, So after the mining slope sliding slope stability and the governance of it is very important and necessary.In this paper, based on Henan archaeologists empress landslide,Recalling the first landslide stability and the development of treatment technologies.It also introduced some kind of numerical analysis methods and Analysis of the progress of these methods.In determining the content and basic ideas of this study, based on First outlined by the provincial archaeologists empress landslide natural geological environment, mining conditions,adding engineering geological conditions for the evaluation.In combination with the theory of mine lakes deformation analysis and research,Landslide stability of this study to determine the impact of the major factors, including the decline of rock types, rock structures, seam depth.mining conditions, landslides and tectonic patterns, a preliminary determination of landslides for stability;Limit balanced discussion in the process of calculating the slope stability, and give full consideration to the impact of mining.eventually selected the most reasonable limit equilibrium method for the stability of the landslide is calculated and the results are analyzed.with the actual conduct of the control,The results fully demonstrated the accuracy and balance of the limit in selected mining landslide stability in terms of applicability.Relying on paper, the authors introduce the basic tenets NCAP-2D finite element analysis program.Landslide and used in the construction of a simulation of the landslide at the excavation of stress, strain characteristicsAs a result of excavation and the excavation face, slope, the slope of plastic there,fully reflect the impact of underground mining on the slope stability and eventually lead to regional instability in the landslide.Finally, a simple method to slide into management and research, this study aimed at the actual situation,the most rational management program, choosing the most economical and reasonable approach is that grouting, and the classification of grouting, grouting process.Grouting a brief theoretical analysis of the treatment results of the finite element simulations, the treatment of stress,Contingency plans and plastic features prominent characteristic curve, as compared with previous mining results of the analysis process.Stability analysis for the evaluation after treatment,NCAP-2D also verified finite element analysis software in the calculation of slope stability practicality.
