Mathematical modeling and fuzzy approach for disaster analysis on geo-spatial rock mass in open-pit mining

Abstract

Due to the complex nature of open-pit mining rock mass, multiple variables has a significant impact on slope stability, which is difficult to evaluate under disaster conditions. The damaged rock slope stability analysis using fundamental fuzzy model is established using the concept of fuzzy measurements upon the basis of statistical analysis on large amount of measured data in Geo-Spatial study. Because of the marked “fuzziness” of the variables is analyzed in this research, the slope stability issues under disaster conditions has been analyzed using Fuzzy Mathematical Theory (FMT) which examines damaged rock slope deformation failure at the open-pit mining. The fuzzy probability formula for rock mass deformation failure, and a numerical method for calculating the fuzzy probability, is derived by applying the theory of variation probability measurements in open pit mining. Here the damaged rock slope under disaster conditions in open-pit mine area has been analyzed and The fuzzy based disaster data management concept has been proposed for analyzing the disaster in open-pit mine area for the damaged rock due to disasters. Finally, the formulation of the Gauss–Legendre is a three-point technical illustration of damaged rock slope which has been used in the open pit. The practical calculation demonstrates that the technique is used for evaluating the slope stability problems in the metal mine opencast under disaster conditions.
