| Location | SQ-HEN-CN |
| Geographical representativeness description | Compared with other mining areas in the province, Yongcheng mining area has higher advantages in resource reserves and reserve-mining ratio. It is now divided into 5 exploration coal mining areas and 2 coal prospecting prediction areas. The occurrence of coal seams in Yongcheng mining area is relatively stable, and the mining technical conditions are relatively simple. The dip angle of the mineable coal seam is relatively gentle, which is suitable for mechanized mining. |

| Use advice for data set | When utilizing this LCA data set for the Yongcheng mining area, it is important to take into account the specific conditions such as the relatively simple mining technical conditions and the mechanization of the mining process. Inventory analysis should consider fuel and raw material consumption, as well as waste gas emissions from the mining process. This data set should be used in accordance with the regional geological characteristics, and it is recommended to update the data regularly to reflect any changes in mining technology or environmental regulations. |
| Technical purpose of product or process | The coal extracted from the Yongcheng mining area is primarily used for energy production due to its resource reserves and favorable mining conditions. The coal seams' stable occurrence and gentle dip angle facilitate mechanized mining approaches, making the coal suitable for use in power generation plants, industrial boilers, and various manufacturing processes requiring thermal energy. |

| General comment on data set | The production process of the coal mining link belongs to the underground operation, which needs to excavate the roadway from the ground to the underground, including the main links such as drilling and blasting, cutting, mining and loading, transportation and the auxiliary links such as power supply, ventilation, drainage, support and lighting. During the whole mining process, there are direct carbon emission sources such as fuel combustion, spontaneous combustion of stacked coal, coalbed methane emission, raw material and transportation consumption, as well as indirect carbon emission sources such as electricity and underground dust removal water. |

| Technological representativeness | |
| Technology description including background system | The production process of coal mining includes mine field development, roadway excavation, support, mining and so on. The underground mining mainly mines the coal buried in the ground and transports it to the ground through the excavation of the roadway. The inventory analysis of this link mainly includes the consumption of fuel, raw materials, and the emission of waste gas. |
