Analysis of the Characteristics of CH4 Emissions in China's Coal Mining …
The coal mine CH 4 emission factor of low-gas mines is the smallest at 0.01 m 3 /t, and the highest in Yunnan Province, reaching 17.14 m 3 /t. Among the high-gas mines, the emission coefficient of coal mines in Shaanxi is the lowest at 1.3 m 3 /t, and Chongqing has the highest emission factor of 94 m 3 /t.
