Description
This dataset represents the life cycle inventory of raw coal production cradle-to-gate, covering all activities related to raw coal production but excluding coal washing and beneficiation processes, as well as direct or indirect greenhouse gas emissions associated with the production of equipment such as conveyors and mining vehicles, personnel commuting, and daily office operations during coal production. The dataset was formed by consolidating data from multiple sources based on national standards such as "Cleaner Production Standard for Coal Mining and Selection Industry" (HJ 446-2008), "Pollutant Discharge Standard for Coal Industry", and "Soil Environmental Quality Standard of the People's Republic of China National Standard", and can represent the average production level in China.
Activity Description
This dataset describes the extraction of raw coal. Chinese coal mining processes can be divided into two main categories: open-pit mining and underground mining, with the specific choice depending on geological conditions, thickness, and depth of coal seams. Open-pit mining includes drilling, blasting, loading, crushing, transportation, waste dumping, pollution treatment and disposal, and ecological restoration. Underground mining includes tunneling, coal extraction, mechanical equipment, underground and in-plant transportation, ventilation, pollution treatment and disposal, and ecological restoration and management.
Process Description
In this dataset, raw coal refers to coal that, after being extracted, has only visible gangue removed and has not undergone any processing. Raw coal is an essential component of the global energy supply chain and is widely used in power generation, steel production, and industrial manufacturing.
