Production Steady and Slope Stability Analysis during the Transition Period of Open pit to Underground in Miaogou Iron Mine

Abstract

Abstract: Combined with the actual mine production during the period of open-pit mining to underground transition of Miaogou iron ore，basing on fully mining ore quantity of transition period，put forward different regional potential ore body mining scheme and safety protection measures，achieved by the open-pit mining to underground mining production a smooth transition，with high feasibility and economic benefits.

Key words: Transition from open pit to underground, Transition period, Measures for stable production, Stability analysis
