Slope stability analysis of slope stability calculations aregiven in the final analysis of the quantitative evaluation of the process,their usual method of calculating the limit equilibrium method. Andbecause of natural conditions and the actual project the existence of manyuncertainties, the results have led to the slope great uncertainty, for whichthe slope engineering reliability analysis it is very necessary and urgent.Slope reliability analysis methods commonly used for the Monte Carlomethod.In this paper, we take the Open-pit mine Dagushan B, C Districtslope as thesis research project object, the slope of the study areaconducted a survey of the geological lithology. Through the typicalregional rock slope on the rock mechanics laboratory experiment, obtainsthe rock strength and rock density parameters.Measured through the useof online distance statistics JOINTED approximation of B, C at five testindicators point to speculate RQD of rock.The use of joint investigationof the statistical window method for district B, C areas to measure theslope of the joints and statistics, access to the joint spacing and joint tracelength distribution of the results, and obtained the slope of rock jointsoccurrence. Geomechanical rock mass classification based on CSIR,hoek-brown strength theory and Monte Carlo methods, the use of Visual Basic 6.0 programming analysis of rock mass strength of the randommethod of a new attempt. Moore Coulomb strength theory based on thelimit equilibrium method and theory, analysis of the open iron DagushanB,C District, slope stability, and the use of Monte Carlo and statisticalmoment method for iron ore slope Dagushan reliability analysis todetermine the slope of the reliability index and failure probability of theopen iron ore mining were Dagushan slope failure risk assessment.
