Description
This dataset represents the life cycle inventory (cradle-to-gate) from coal mining to raw coal production, covering all activities related to raw coal production, but excluding coal washing processes, as well as direct or indirect greenhouse gas emissions from equipment production (such as conveyors and mining vehicles), personnel transportation during coal production, and daily office operations. The dataset was formed by merging data from multiple sources based on national standards such as "Clean Production Standard for Coal Mining and Preparation Industry" (HJ 446-2008), "Emission Standards for Pollutants from the Coal Industry", and "Soil Environmental Quality Standards of the People's Republic of China", and is representative of the average production level in the South China region.
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
Raw coal refers to the product obtained from coal mining that has not undergone washing, screening, or processing, and has only been manually sorted to remove rock and impurities.
