Description

With the increase of mining depth, the gas content of coal seam increases. Users should apply this data specifically for assessing methane emissions in the context of underground coal mining for the specified region and time frame. Take note that the methodology adheres to the IPCC Guidelines utilizing the average emission factor method. Care should be taken when extrapolating these figures to different regions or time periods due to changes in mining technology and practices.

Technology

The amount of methane discharged into the atmosphere from coal mines in China in 1994 and 2000 was investigated and studied. Through the collation and analysis of a large number of mine gas grade identification data of state-owned key, state-owned local and township coal mines, the amount of methane drainage and utilization in mines was investigated, and some laboratory measurements were supplemented. On this basis, in accordance with the IPCC Guidelines for the revision of the second.
