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. 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.
