Study on application of FLAC to analysis on stability of artificial high slope in large surface coal mine

The slope of the dumping site is an artificial made high slope.The design and calculation of the stability to be conducted would be an unavoidable important engineering issue in the daily production of the surface mine.Base on the limit balance theory,different slope stability analysis methods were widely and effectively applied to the engineering practices.Taking Shenhua Beidian No.1 Surface Mine as an example,several analysis and calculations with FLAC/ SLOPE showed that the design parameters of the dumping site of the No.1 Surface Mine could meet the mine safety production conditions and could be rational,safety and feasible in technology.The paper provided the proposals on the slope control of the dumping site.
