Abstract
When operating backhoes in coal-bearing zones of quarry fields at Kuzbass open-pit mines, a number of issues arise related to determining their most rational use. For instance, the problems of choosing the optimum mode of digging – top or bottom digging in those or other mining and geological conditions; establishing the boundary conditions for loading of the upper, lower or at the excavator placement level have not been completely solved; the stability parameters of the excavator when working, for example, on benches made of different-strength rocks and weakened by tectonic and other disturbances, as well as a number of other problems have not been fully studied. This article presents the results of simulation of face blocks parameters when operating Komatsu PC 1250 backhoe with upper digging and loading into dump trucks with carrying capacity of 220 tons – BelAZ-7530. It is established that parameters of bottom-hole blocks at operation of backhoes by top-digging should be linked also with the capacity of the body of the applied dump truck.
