This dataset describes the mining of raw coal. Coal mining processes in China can be divided into two main categories: open-pit mining and underground mining. The specific choice depends on factors such as the geological conditions, thickness, and burial depth of the coal seam. Open-pit mining includes drilling, blasting, loading, crushing, transportation, dumping, pollutant treatment and disposal, and ecological restoration. Underground mining includes tunneling, coal extraction, machinery and equipment, underground and in-plant transportation, ventilation, pollutant treatment and disposal, and ecological restoration and remediation.
