Abstract: From the global climate change conference to the low-carbon development of countries around the world, carbon emission reduction has become a common global aspiration and urgent requirement. China has always been a powerful promoter and important practitioner in addressing climate change, and implemented greenhouse gas emission reduction responsibilities through such measures as top-level design, industrial upgrading, structural adjustment, and energy conservation and emission reduction. As a major coal producer, China’s state-owned coal mine methane and high-methane mines account for 46% of the total number of mines. Coal mining produces a large amount of gas every year, of which ventilation air methane emissions account for about 90%. The CH4 concentration of ventilation air methane is generally lower than 1%, and is difficult to directly being utilized, and its volume is large and wide-ranging. Therefore, it will be the focus of future methane utilization technology development. Although demonstration projects for industrial utilization of ventilation air methane have been constructed in recent years, most companies still empty it directly, which not only wastes precious resources but also causes serious pollution to the atmospheric environment.

Key words: Coal mine methane, comprehensive utilization, carbon emission reduction, energy
