Coal in China - Wikipedia

Coal mines in pre-industrial China. Ancient people in current China started using coal around 6 000 years ago. Historians suspects that the Chinese were involved in the surface mining of coal around 3490 BC, pioneering the pre-modern world. Fushan mine uses to be pointed out as the earliest coal mine in the ancient world and started around 1 000 BC.

Underground Coal Mining Methods

Underground coal mining mainly include the process of drift, slope, and shaft mining, and actual mining methods include longwall and room and pillar mining. Drift Mines enter the side of a hill horizontally and mine the coal within the hill. Slope mines usually begin in a valley bottom, and a tunnel slopes down to the coal surface.
