WhatsApp: +86 18221755073Auger mining is a method for the extraction of coal by the boring of an auger into a coal seam. This is usually associated with open-pit or strip mining when it becomes uneconomic to recover coal due to excessive depth and overburden removal. The use of an auger is controlled by the dip of a seam and the engineering properties of the coal.
