Abstract
The excavator moving pitch does not belong to the generally accepted parameters of the open-pit mining system, but its precise determination is very important, because it directly affects the volume and configuration of the face block. When forming the composition of the excavator-haul truck complex, the question arises about the mutual compliance of excavation-loading and transportation equipment from the point of view of the possible achievement of a complete match between the volume of the face block and the volume of the dump truck body. However, changes in mining and geological conditions will inevitably entail a mismatch of the above parameters. This issue is very relevant due to the constant complication of mining conditions. This article presents some provisions of the methodology of face block parameters adaptation by changing the excavator moving pitch to the dump truck body volume; the equipment complex is represented by the common models Komatsu PC 1250 and BELAZ 7530 with payload capacity of 220 tons.
