Dump Load Shedding and Slope Angle of Optimization Design

Abstract:

In view of the local conditions of Xingshan Iron Mine North Dump, an economically safe load shedding scheme was determined. Based on critical sliding field technology, the most dangerous slip surface can be searched of different waste-dump slope angles. Once the most dangerous slip surface is fixed, limit equilibrium methods can be used to analyze the stability of the slope. The corresponding slope angle of minimum allowable safety coefficient under the most unfavorable condition was defined as the optimal slope angle of this section, and the minimum optimal slope angle of all the sections of dump was determined as the final optimal slope angel of the whole dump. This method was not any practical but also extremely economical, which can ensure the absolute safety of dump and its surroundings.
