Auger mining is employed to increase reserves accessing coal lying beyond the economic reach of conventional stripping operations. Coal Augering Services' new generation of coal recovery augers are capable of drilling holes with diameters ranging from 1.2m up to 1.9m to a depth of more than 200m and augering up to 2400 tonnes in a 12-hour operating shift.

Auger mining method for recovering coal by boring into a coal seam at the base of strata exposed by excavation. Normally one of the lowest-cost techniques of mining it is limited to horizontal or slightly pitched seams that have been exposed by geologic erosion. Augering is usually associated with contour strip-mining recovering coal for a limited depth beyond the point where stripping becomes
Auger mining. Auger mining is usually associated with contour strip mining. With this method the coal is removed by drilling auger holes from the last contour cut and extracting it in the same manner that shavings are produced by a carpenter’s bit. Coal recovery rates approach 60 percent with this method.
In addition the scope may be varied to include pit preparation ready for auger mining water cartage for auger working area dust suppression and coal haulage. Contract auger mining costs are typically lower than surface mining making it a cost competitive mining option even in
Jan 25 2018 While open-pit mining involves extraction of coal from an open pit in the ground strip mining includes stripping surface layers to reach coal deposits. Contour strip mining area strip mining and auger mining are other techniques followed in surface mining of coal. In case of strip mining coal seams are reached by removing the surface above them.
