Determining the optimal operating parameters of the wheel bucket excavator at the work in overburden

The purpose of this paper is to determine the optimal operating parameters of the excavator bucket wheel in different working conditions viewed from geomechanical characteristics of explored material, hydro-geological characteristics of the material and technological capabilities for the work of the excavator. In the open pit "Brod - Gneotino" discovery of coal layers is performed by two waste ETD (Excavator – Transporter – Disposal) - system so that both systems exploitation is carried out by one excavator SRs - 2000. It will show the possible technological schemes of work of the excavator bucket wheel SRs - 2000 which will be obtained the optimal parameters for the operation of the excavator in certain conditions
