Abstract

Taking a L working face of open-pit to underground mining in Wuhai coal mine as an example, based on the numerical simulation software FLAC3D which made a detail analysis of deformation and mechanism of rock slope aimed at the two different mining schemes of from inside to outside and outgoing. The results proved that: When the mining sequence is from inside to outside, the slope to the underground mined-out area, which is good for slope stability; On the contrary, it would be accelerate the failure speed, adverse to the slope stability. So underground mining should be adopted by the outward push of design, in order to reduce the landslide damage. The result is useful in surface-underground combined mining operations.
