Comprehensive Stability Research And Governance On Coal Gangue Slope

Because of large amounts of Coal Mining, large quantity of solid waste (Coal Gangue) emitted from the process of Coal mining and Coal washing. Coal Gangue disposal will not only occupy large tracts of land but also pollute the enviroment, agricultural land and water.The Coal Gangue will also pose spontaneous combustion hazards, prone to collapse during the rainy season and choked the rivers with disastrous consequences. Coal gangue slope is widespread existed, if the Gangue Slope sliding it will cauce huge disaters. Therefore, take urgent measures to deal with Coal Gangue Slope is necessary. This paper combine with the characteristics of Coal Gangue itself, fully considering the uncertainties during the process of packing, Calculate the safety factor and reliability under finite element methods and reliability analysis methods. Solving the potential sliding surface of the slope, obtain reasonable evaluation of the Coal Gangue slope.Through the field sampling and indoor test, get the relevant paremeters of the Coal Gangue Slope, combine with the actual situation of the Coal Gangue slope and then establish the Numerical Simulation Models, use Numerical Simulation software FLAC^3d solving the corresponding security coefficient, sliding surface and the corresponding stress position, compare the results of Numerical Simulation with theFinite Element MethodS and the Methods of Reliability Analysis, combining with the actual conditions, formulate feasible scheme of Coal Gangue Slope. Through the investigation on the effect of governance, the methods has good effect and important practical and academic significance.
