Abstract

Deepening of mining comes with constant evolution in geometric shape, load and engineering geological structure. How to accurately grasp the development trend inducing slope stability during the evolution process is a prerequisite for guaranteeing slope safety and avoiding disasters. This paper takes the Zijinshan gold-copper mine slope project as the research object. Based on the mine engineering geology and deformation monitoring data, rolling combination forecasting method is established for slope deformation. Drawing upon the long-term forecasting theory of phase space reset, monitoring point deformation of mine slope is forecasted. The research results indicate that the combination forecasting result after phase space reset has lower residual standard deviation than single forecasting result with increased forecasting accuracy, which reduces cyclical fluctuation of forecasting results in the medium and long-term forecasting.
