Study on landslide catastrophe mechanism and control strategy for open-pit coal mine

This paper defined the main types and key influencing factors of landslide, and analyzed landslide catastrophe mechanism on the basis of analysis on engineering geological condition of slope. The course of landslide catastrophe was numerical simulated by adopting the nonlinear, large deformation finite element software of FLAC.Based on the previous study, the new technology of "the pre-stress anchor frame beam and high press splitting and grouting to reinforce slope" was proposed, furthermoreit’s reliability was verified to be rational and effective through numerical simulation and field test.
