Impact Assessment of Mining and Geological Factors of Kuzbass Coal Mines on the Level of Their Power Consumption

摘要

The processing results of the extensive statistical material characterizing the level of power consumption of Kuzbass coal mines are presented. At the same time, in the formulation of the research problems, the authors have come from the fact that the power consumption of mine is a function of many variables. This has revealed the tendencies not only in development of power consumption, but also many other factors determining its level: deepening of mining operations, growth of gas content and, therefore, increase in electric power costs for ventilation of mine roads, increase in water inflow, etc. On the basis of statistical researches it is shown that the worsening of mining-and-geological conditions of Kuzbass coal mines leads to an increase in specific consumption of the electric power. Quantitative estimates of the impact of the mining-and-geological and mining factors on the mine power consumption are established. The presented results can be used to solve the task of increasing the efficiency of power usage in the coal mines, both at the design stage, and during normal operations of the enterprise.
