Surface Mining Auger mining was introduced to the West Virginia coalfields in the 1940s. Today, auger mining continues to be used as a surface mining method in West Virginia, usually on contour surface mines where augers drill the last available coal from the highwall. A recent offshoot of auger mining is the development of highwall miners.
