Coal mining Choosing a mining method Britannica

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 carpenters bit. Coal recovery rates approach 60 percent with this method.

Surface Mining Methods ILO Encyclopaedia

Mechanical drilling and blasting are the first steps in extracting ore from most developed open pit mines and are the most common method used to remove hard rock overburden. While there are many mechanical devices capable of loosening hard rock, explosives are the preferred method as no mechanical device can currently match the fracturing capability of energy contained in explosive charges.
