Abstract
The publication discusses the main ways to increase the level of energy efficiency in electric networks during underground coal mining, including coal mines that are dangerous due to sudden emissions of gas and dust. The results of the conducted studies, including experimental ones, at the high-performance dredging site of a coal mine are presented, which made it possible to determine the main trends in improving energy efficiency, namely: by increasing the level of supply voltage; by reducing the level of influence of higher harmonics on the operating modes of the main technological equipment; as well as increasing the level of rationing of the operating modes of the main technological equipment of high-performance dredging sites of coal mines.
Keywords
