| Use advice for data set | Users of this data set should consider it in the context of environmental impact assessments regarding methane emissions from coal mining activities. When using the data, they should adopt the IPCC's 'Tier 2' approach with regional average methane coefficients for calculation, as applied in the creation of the dataset. Due attention should be given to technological changes since 2000 which may have altered the efficiency of methane capture and utilization in coal mines. If used for comparative studies or temporal analyses, adjustments may be required to account for technological and methodological advancements over time. |
| Technical purpose of product or process | The process described is the underground extraction of coal within the 'East China' region, specifically focusing on the emission of methane (CH4) during the coal mining activities in the year 2000. This coal is likely used as a fuel source in power generation and other industrial applications requiring high-grade coal. Particular attention is paid to the methane emissions, suggesting that this data set may be especially relevant for studies on environmental impact, air quality control, greenhouse gas inventory, and climate change mitigation strategies. The coal extracted might also contribute to raw materials for the production of coal-based chemical products. |

| 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. |
