| Use advice for data set | When utilizing this data set for Life Cycle Assessment or other environmental impact analyses, users must consider that the methane emission figures are specific to the underground coal mining process of the 'North China' region in 1994. To maintain accuracy, users should not extrapolate these figures to other regions or time periods without proper justification. Users should also consider additional factors such as technological advancements and changes in mining practices that may have happened since 1994, which could affect methane emissions. Appropriate adjustments based on current IPCC guidelines should be made if applying this data to modern scenarios. |
| Technical purpose of product or process | The industrial process described involves the extraction of coal through underground mining activities, specifically within the 'North China' region in the year 1994. This coal is intended for various energy production and industrial applications, ranging from electricity generation to serving as a raw material for manufacturing processes. The focus of this data set is on methane (CH4) emissions that occur during the coal mining process. |

| 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.The weighted average methane coefficient of coal production in each region of China and the methane emission coefficient of coal mining process in each region of China are obtained by the average emission coefficient method. |
