Soft High Steep Rock Slope Landslide Prediction

Open-pit mine landslide forecast forecast is an extremely complex and diverse problems, in the open pit slope stability analysis and prediction of slope, the selection of mechanical parameters is essential, especially in the high and steep slope of soft rock system, strength of rock mass fragmentation reasonable assessment of a reasonable calculation of selected parameters on the slope stability analysis and prediction of slope deformation impact; open pit landslide forecasting technology and fracture assessment of rock mass strength Xiaolongtan Mining slope, one of the important lessons, in this paper Buzhaoba help open the North, the West Slope of the strong rock evaluation, prediction of landslide deformation as an example of the focus of research and discussion, and achieved the following results:1) Analysis of rock mechanics parameters summarizedThe main focus of this article to Buzhaoba report Geological Survey open-pit rock mechanics experiment provided information on the basis of the analysis for the study, after analysis of induction found that the mechanical parameters of rocks (internal friction angle and cohesion) of the index is too subject to tangent distribution. Application of maximum likelihood estimation method from 1994 to 2005 survey report of the results of many maximum likelihood estimation to obtain the results of statistical tables for the future calculation of slope stability and slope deformation provide a large number of forecast parameters of rock mechanics basis. Provided the estimated accuracy, yo Festival unnecessary costs of geological survey.2) the use of RMR and rock into the SGI on the assessment and the establishment of the assessment into the pattern of mathematicsThis article focuses on the parameters of the rock mass quality assessment practices (RMR) and rock mass strength parameters of the assessment method (GSI method) The principle and analysis of two aspects of the strengths and weaknesses of the assessment in accordance with the characteristics of the two methods, using function-building non-linear mathematical pattern identified point of contact between the two, through the contact points of the RMR on the GSI method coupled analysis method to improve the accuracy of the evaluation of rock mass strength, rock mechanics parameters to make the selection of more competent for slope stability analysis and deformation prediction to lay a solid foundation.3) open-pit mine slope deformation prediction method for forecastingIn this paper, the use of open-pit mine Buzhaoba surface displacement characteristics of the measured data in line with the gray theory and the theory of chaotic time series to predict the requirements of fully integrated open-pit slope monitoring of the actual situation, respectively Xiaolongtan Buzhaoba mines to help the North and West to help the next one to within two years the trend of the slope deformation prediction analysis, the gray theory and the theory of mixed results Tuen basically in line with the actual results, the trend is consistent deformation, slope deformation projections indicate that in the near future will not produce more large-scale deformation of the landslide, only the Regional Council, such as the West to help the west corner of the North to help the west, is also the M301, M302 west to places such as the possibility of deformation of Health and local landslides.
