| Use advice for data set | Users should employ the provided data with caution, ensuring its application is limited to the methodological and geographical context specified, namely, methane emissions from underground coal mining in central-south China during 1994. When integrating this data into broader life cycle assessments, users must account for temporal and regional limitations. The IPCC Guidelines revised methodology, specifically the use of the average emission coefficient method, should be adhered to when calculating emissions. Users should also note the absence of subsequent operational or post-operational data, as the study concentrates on the emission factors relevant to the 1994 and 2000 time frame. |
| Technical purpose of product or process | The described process relates to the underground coal mining industry in the central-south region of China specifically detailed for the year 1994. This data set is used for assessing methane emissions associated with coal extraction activities. Methane emissions data is crucial for understanding the environmental impact of coal mining operations and for devising strategies to mitigate greenhouse gas release. This data can be used by environmental researchers, policy makers, and industries to monitor and report on emission trends, and is applicable for climate change studies, carbon footprint calculations, and the creation of emissions inventories. |

| General comment on data set | According to the requirements of the Intergovernmental Panel on Climate Change ( IPCC ) revised guidelines in 1996, the methane emission from underground mining, open-pit mining and post-mining activities in China was estimated. After deducting the use of methane in methane extraction, the amount of methane discharged into the atmosphere by coal mines was obtained. |

| Technology description including background system | 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. |
