Abstract: Open-pit coal mines can recycle resources by underground coal mining but it will lead to subsidence of upper slope, and may cause geological environmental disasters such as landslides. A fuzzy comprehensive evaluation model of the slope stability in coal mining subsidence areas is proposed. Based on the model the evaluation of slope stability in the subsidence zone in Antaibao open pit coal mine is carried out. By conducting the qualitative and quantitative analyses simultaneously, the evaluation results are more scientific than the qualitative description only and semi-quantitative analysis. According to the results of stability evaluation division, to ensure the mine safety production in the danger zone, the monitoring network composed of 20 monitoring points successfully implements monitoring and forecasting for stable condition of slopes.
