Kuzbass coal mines are equipped with powerful mining equipment; it is CME excavator type with bucket capacity from 4.6 m3 to 20 m3. To evaluate the efficiency of the excavation processes, a universal criterion was used – the value of specific energy consumption (kW h/m3). The dependences of excavator efficiency on the quality of rock blasting, estimated by the diameter of the average piece in the shot pile, are obtained. The relationship between the efficiency of excavators CME - 4.6, CME – 8, CME – 12.5, CME – 20, their energy intensity and the diameter of an average piece in the shot pile is determined.
