Description
This dataset represents a life cycle inventory (cradle-to-gate) covering the entire process from coal mining to the production of raw coal. It includes all activities associated with raw coal production, but excludes coal washing and preparation processes, as well as direct or indirect greenhouse gas emissions from the production of equipment such as conveyors and mining vehicles, personnel transportation, and routine 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 Washing Industry" (HJ 446-2008), "Emission Standard of Pollutants for Coal Industry", and "Soil Environmental Quality Standard of the People's Republic of China", and is representative of the average production level in Inner Mongolia.
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
Inner Mongolia is rich in coal resources with a complete range of coal qualities. The identified coal-bearing area exceeds 100,000 km², and there are 24 coal reserves each exceeding 100 million tons. These are mainly distributed in the Dadaqing Mountain coalfield, Jungar coalfield, Dongsheng coalfield, Zhuozishan coalfield, Wuda coalfield, Shengli coalfield, Huolinhe coalfield, Bayan Heshuo coalfield, Bayan Hua coalfield, Bayanbaoleige coalfield, Zhalainuoer coalfield, Dayan coalfield, Yimin River coalfield, Chenbarhu Banner coalfield, and Pingzhuang-Yuanbaoshan coalfield. The Inner Mongolia Autonomous Region has a complete range of coal types. Coking coals include gas coal, fat coal, coking coal, and lean coal; non-coking coals include贫 coal, anthracite, weakly caking coal, non-caking coal, long-flame coal, lignite, and natural coke. Moisture content ranges from 0.78% to 18.52%, ash content from 4.02% to 47%, volatile matter from 2.9% to 49.73%, total sulfur from 0.09% to 4.06%, phosphorus content from 0.001% to 0.208%, and the net calorific value on an as-received basis (Qnet,ar) ranges from 6525 to 8224 kcal/kg.
