Ways to increase the efficiency of engineering processes when forming high-density arrays of disperse materials

One of the most important production operations in open pit mining is dumping. The depth of open pit mines increases constantly and the volume of overburden rocks also grows. Overburden is truck-delivered to the dumps. Fractional composition of overburden is diverse. In the early years, loose rocks were transported to the dumps from the upper horizons to the lower levels of the dumps, and in subsequent years - hard rocks. In this view, due to the low strength and stability of the dump mass, it is usually not possible to provide safe working conditions. The mining safety can be increased due to the compaction of rocks composing the dump mass. Based on the analysis of technologies for compaction of dispersed materials using known equipment, a self-propelled vibration device is proposed for the formation of a stable dump mass. The use of a vibrating function element in the design, which implements a polyharmonic vibration mode, will expand the scope of its application during the open pit mining.
