Electric shovels, pumps and coal handling plants consume 75% of the total electricity consumption of an opencast coal mine. In this paper, a modelling framework has been developed for electrical energy use benchmarking (internal as well as cross-sectional) of the mine. To develop a mine specific model for benchmarking electrical energy use statistical approach (linear regression method) has been applied. Specific power consumption (SPC) is used as a benchmarking index to assess the operating energy performance of a specific mine and multiple coal mines of India based on the field studies. Seasonal analysis of the electrical energy usage has also been analysed. Our results show the benchmark SPC as 0.50 kWh/t and the energy-saving potential as 10.7% for a single mine and the benchmark SPC of multiple coal mines as 0.52 kWh/t. The result concludes that SPC widely depends on its capacity and mining method and the developed model are useful for benchmarking and targeting for efficient electrical energy use in opencast mine.</p></abstract><trans-abstract xml:lang="ru"><p>На угольных разрезах потребляется большое количество электроэнергии. Электрические экскаваторы, насосы и установки для перегрузки угля потребляют 75 % от общего объема электроэнергии. В данной работе представлена схема моделирования для проведения сопоставительного анализа (как внутреннего, так и перекрестного) потребления электроэнергии на предприятии. Для разработки модели сопоставительного анализа потребления электроэнергии на конкретном предприятии был применен статистический подход (метод линейной регрессии). Удельное потребление электроэнергии (УПЭ) используется в качестве контрольного показателя оценки энергоэффективности конкретного предприятия и нескольких угольных предприятий в Индии на основе полевых исследований. Также проведен сезонный анализ потребления электроэнергии. Согласно полученным результатам контрольный показатель УПЭ составляет 0,50 кВт-ч/т, а потенциал энергосбережения для одного предприятия – 10,7 %. Для нескольких угольных предприятий контрольный показатель УПЭ составляет 0,52 кВт-ч/т. Сделан вывод о том, что УПЭ в значительной степени зависит от производственной мощности, а разработанные метод и модель горных работ позволяют выполнить сопоставительный анализ и достичь эффективного энергопотребления на разрезах.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>электрический</kwd><kwd>сопоставительный анализ</kwd><kwd>внутренний анализ</kwd><kwd>перекрестный анализ</kwd><kwd>удельное энергопотребление</kwd><kwd>потребление энергии</kwd><kwd>разрез</kwd></kwd-group><kwd-group xml:lang="en"><kwd>electrical</kwd><kwd>benchmarking</kwd><kwd>internal</kwd><kwd>cross sectional</kwd><kwd>specific power consumption</kwd><kwd>energy use</kwd><kwd>opencast mine</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Авторы выражают благодарность директору Центрального института горного дела и научно-исследовательских работ по изучению и использованию топлива за разрешение опубликовать данную работу.
