Influence Analyzing of Slope Stability with Setting of Crushing Station in Semi-Continuous Technology

According to the analysis of the semi-continuous mining system with crushing station set on end-slope and the relation with working wall and non working wall, the calculation method of uncovered end-slope area and the coefficient of slope stability was elicited, considering the external load caused by crushing station location. The variation curve and the law of stability coefficient were also obtained. Combining the field practice, the research conclusion indicates that the crushing station setting of semi-continuous mining system would affect not only the truck transportation distance and the economy benefit, but also the slope stability, which can be used as the theory support to the setting of crushing station in semi-continuous mining system.
