Abstract
Analysis of major accidents at the Severnaya (2016) and Listvyazhnaya (2021) coal mines revealed a number of problems related to ventilation. The aerological safety of a coal mine is achieved by the correct choice of technological solutions in the design, and in the process of coal mining – by operational control of the state of the mine atmosphere and gas emission control. Currently, coal mines, due to the high gas content, use a whole range of measures, including new ventilation schemes, various types of degassing and gas suction. At the same time, design and regulatory documents do not offer solutions for calculations in a single system of all thrust sources. As the conducted studies have shown, three-dimensional modeling allows us to evaluate the mutual influence of all methods of gas emission control in a single system.
