【Abstract】 This paper discusses the formation mechanism of sliding-debrisflow in the refuse dump at 1932 level in the O-Kou Open Pit Mine, Shanxi Province.Based on the field survey, simulation tests and theoretical calculation, the following points can be drawn.1. If rock materials alone are discharged into the dump, it is almost impossible for sliding-debris-flow to occur even the dump slides after rainfall.2. If rock and soil materials are discharged mixedly, it is likely for the water-debris-flow to happen after rainstorm even the dump does not slide.This type of water-debris-flow has only a slight damage to the tailings dam below the dump.3. If rock and soil materials are discharged mixedly, it is likely for the sliding-debris-flow to occur after rainstorm under the conditions that the dump and its base are saturated, and for the slip occurs. This type of sliding-debris-flow has a bad damage to the tailings dam below the dump.更多还原
