На основе анализа горно-геологических условий разработки угольных месторождений Вьетнама, существующей нормативной базы по обеспечению безопасности при добыче угля, применения методов расчета воздухопотребности очистных и подготовительных выработок угольных шахт по метановому фактору и современных методов математического моделирования вентиляции горных выработок шахт и рудников, разработана процедура анализа эффективности управления воздухораспределением по предложенному показателю – коэффициенту энергетической эффективности вентиляционной системы, определяемого коэффициентами полезного использования воздуха и энергетической эффективности. Получены соотношения, определяющие связь между аэродинамическим сопротивлением отрицательных регуляторов, количеством одновременно разрабатываемых очистных и подготовительных забоев, производительностью вентиляторов главного проветривания и потребляемой электрической мощностью.

Based on the analysis of the mining and geological conditions for developing coal deposits in Vietnam, the existing mining safety regulations, the application of methods for calculating the air supply of working and development faces using the methane factor and modern methods of mathematical modeling of the ventilation of mines threr was developed the procedure for analyzing the efficiency of air distribution management considering the proposed indicator - energy efficiency coefficient for ventilation systems, determined by the efficiency of air use and energy consumption. Relations have been obtained that determine the relationship between the aerodynamic resistance of negative regulators, the number of simultaneously developed working and development faces, the performance of main ventilation fans and the consumed electric power.
