Abstract

The growth in the power supply of coal mines over the past decades has had a significant impact on their power consumption. The use of outdated materials for assessing the coal mine energy characteristics may lead to large calculation errors. At the same time, the problem of reducing the energy intensity of coal mining does not lose its relevance. However, in order to achieve it, it is necessary to take into account the current level of development of the mechanized complex of excavation areas. The widespread introduction of SCADA systems and the development of methods for big data processing makes it possible to collect large arrays of measurements and study the power consumption of mining equipment. In this paper, on the basis of extensive arrays of electrical load measurements and technological parameters, a statistical analysis of the load of a modern Eickhoff SL 900 longwall shearer of the Kuzbass coal mine is carried out.

Summary

Introduction

Steam coal prices were at a low level throughout 2020, driven by a slump in industrial production and lower electricity demand triggered by the Covid-19 pandemic. Cold winter of 2020-2021 in Western Europe and the USA showed that energy systems based on renewable energy sources still lack sufficient reliability in volatile climatic conditions In this regard, a complete transition to "green" energy is not yet possible and coal-fired generation will play an important role in the overall energy balance for a long time. The program for the development of the coal industry in Russia for the period up to 2035 [2] predicts a change in coal demand by 2035 in the range from -1.16 to +13.95%. To achieve the planned indicators in the coming decades, there will be an increase in the power supply
