Abstract

The exploitation deformation of the slope directly affects the mining production safety and the safety of miners. To determine and predict the slope deformation threshold, the slope deformation and failure law, being influenced by mining activities, is studied using numerical simulation based on finite element strength reduction method and warning threshold of the slope deformation is determined. According to nonintermittent characteristics of mine deformation monitoring, nonintermittent GM (1, 1) model has been adopted to predict the exact value of warning threshold of the slope deformation.
