Analysis on landslide catastrophe mechanism and landslip forecasting for open-pit coal mine

摘要

By adopting the research methods of in-situ investigation, laboratory test and theoretical analysis, the slope sliding mechanics and key factors of effecting stability of the slop in catastrophe was analyzed at Shenli open mine. The working slope was divided into four zones including land sliding zone, potential sliding zone, relatively stable zone and importance engineering zone by analyzing the engineering geological condition and lithological characteristics of slope. By the application of the in-situ monitoring data, the model of forecasting the landslide was built up. Combined with the modified grey model and mutation forecasting model, the suitable method of landslide catastrophe forecasting was given. The in-situ monitoring data and the land sliding condition were verified, which proves the feasibility of the forecasting method.
