An integrated approach to reducing the risk of explosions of blue fuel in coal mines with simultaneous extraction of coal methane

Methane explosions in coal mines are the most dangerous type of accident, they often lead to serious destruction and casualties among workers. The main means of ensuring safety is the timely degassing of mines and coal seams, which requires special equipment, financial and time costs. The discharged gas-air mixture is released into the atmosphere or burned, but the most appropriate way of disposal is to use it as fuel for boilers, turbines and other devices. About 7% of mine methane is usefully used in Russia. The article discusses the problems of implementing such projects, analyzes foreign experience and tools for achieving return on investment in coal methane projects.
