Analysis Of Tianshifu Coal Mine First Coal Gangue Slope Stability And Covernment Measures

A loose deposit tianshifu on coal gangue gangue,and a large amount of accumulation,when the rainfall is large,specially under the long time effect of heavy rain,ay lead to the occurrence of coal gangue slope instability and other geological disasters,there is a landslide,major hidden dangers of landslide and debris flow geological hazards,direct and serious threat to the slope of the Dongshan community and the safety of the railway line.Paper based on detailed field investigation and indoor geotechnical testing,a comprehensive analysis of the summary of the study area the instability mode and draw mechanical parameters and analysis of the study area of coal gangue slope stability influence factors and hazard,the focus of study area gangue 3 profile slope stability research,through on-site investigation,understand the engineering geological and hydrogeological conditions.Through the field sampling and indoor test,the mechanical parameters were obtained,and the stability of the slope was analyzed by the transfer coefficient method and the circular arc method.GeoSlope numerical analysis software was used to simulate the simulation,and the results were verified by the simulation results.By comparing the transfer coefficient method,arc method and GeoSlope numerical simulation method,the feasibility and practicability of using GeoSlope numerical simulation method to calculate the stability of landslide are verified.Through the evaluation of the slope stability,and according to the characteristics of the landslide body and the main influencing factors,put forward reasonable suggestions.
