摘要：
This paper analysis open-pit coal mine slope stability in the first mining with FLAC3D, reveal the mechanism of slope deformation, through analysis the stress and strain nephogram of model ZK8 of the first mining slope, and calculation safety stability coefficient, finally concluding stope slope of the first mining occur slip as circular form under their own gravity. The safety factor of model ZK8 is more than stope slope safety coefficient 1.20, slope is in steady state, obtained the accurate and reliable analysis results of stability.
