Estimation of Energy Consumption of DM-H Drill Rig Main Drive in Far North Conditions

The paper examines factors that determine energy consumption of The main drive and energy characteristics of DM-H drill rig; variability of physical and mechanical properties of coal deposit enclosing rock; impact of geocryological conditions of deposits on drilling and blasting operations; methods of calculating drill rig specific energy consumption-output per manshift dependence; DM-H drill rig energy consumption-process parameters dependence. The paper may be of interest for investigators and engineers engaged in research, design and commissioning of control equipment, current instrument and measurement devices used in industrial applications, and also for undergraduate and postgraduate students in electrical engineering.
