The paper considers the problem of reducing greenhouse gas emissions in the process of coal mining during the coal mine methane utilization in power supply systems. An algorithm to form recommendations for the implementation of CMM generation is presented. A simulation model for one of the Kuzbass coal mines was developed in the PowerFactory software application. The simulation model considers the uneven nature of the power consumption of mining equipment. As a result of modeling, daily power consumption profiles and voltage levels in the coal mine power supply system were determined before and after the implementation of the proposed measures. Based on the results, the technical and economic effects was estimated, which consisted in reducing the direct and indirect carbon footprint, electricity and capacity fees. It has been established that the cost of carbon dioxide emission quotas significantly affects the investment attractiveness of cogeneration projects. Based on the results, recommendations are given to stimulate the development of small generation in coal mines.

The introduction of technologies for active-adaptive control of the operating modes of the power supply systems of coal mines can contribute to an increase in the energy efficiency of coal mining. High-response FACTS devices of the second generation can be used for dynamic reactive power compensation, voltage regulation and limitation of current and voltage harmonic components in conditions of sharply variable electrical loads of mining machines at a breakage face. Evaluation of the effectiveness of the implementation of FACTS devices in the power supply systems of coal mines can be performed using simulation methods.This article discusses the main approaches to the development of a simulation model of a power supply system of a coal mine, mining equipment and FACTS devices. The main results of modeling the joint operation of mining machines are shown. Conclusions about the effectiveness of the use of FACTS devices in the extraction area of a coal mine are made.
