"WAYS TO RATIONALIZE DUMP FORMATION IN ROAD TRANSPORT IN DEEP QUARRIES"
Abstract
The article discusses the formation of dumps with various quarry equipment using the example of the Kalmakir quarry and provides ways to rationalize them. Possible variants of new technological schemes for excavator, bulldozer and conveyor transport are presented, as well as the conditions for a possible increase in their height based on the concept of ensuring the safety of landfill operations. The formation of dumps on mountain slopes and the impact on stability are substantiated, the main factors of which are a decrease in the strength and shear properties of rocks over time, the peculiarities of their filling and the processes occurring in the body of the dump that affect the condition of the base of the dump and the dump area as a whole. The necessity of complex dumping using cyclic-flow technologies (CPT-1, CPT-2) is substantiated. The main operations of the dumping technology using cantilever dumpers are described. Technological schemes of fan-shaped and parallel filling are given. It has been established that, based on the complex terrain and the base of the dump, the most effective dump formation scheme is a parallel one.
