Influence of surface screening plant on the stability of west end slope in Hongshaquan Open-pit Mine
In order to study the influence of surface screening plant on the stability of the west end slope of Hongshaquan Open-pit Mine,the Bishop slope stability calculation method was used to explore the local stability law of the influence of surface screening plant on the upper and lower parts of the west end slope and the overall stability law by comparing the surface load and non-load respectively.The results show that when the surface load of the upper part slope increases,the slope is less affected,so more attention should be paid to the influence of surface load on the stability of the lower part slope and the whole slope.When the total weight of the surface screening plant,coal storage and equipment transportation does not exceed 500t and is located 55 m away from the top crest of the slope,the stability of the overall slope is not affected by the surface load,but the stability of the lower part of the slope is slightly reduced.
