7.3.3: Auger Mining. Earlier in this lesson, you saw the highwall that remains after the ultimate pit limit is reached in a contour mining operation. At that time, I pointed out the possibility of recovering the coal under the highwall, by either developing an underground mine or highwall mining. The former is rarely economically feasible today.

1.. IntroductionAuger mining is a safe and profitable means of residual coal-resource reclamation under the final highwall and has been successfully applied in surface coal mine of several countries, such as Germany, Australia [1].As the coal resources of surface mines in China gradually become exhausted, auger mining will provide a new option for solving the problem of residual coal-resource.

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 relatively recent offshoot of auger mining is the development of highwall miners.

1. Introduction. The proven coal resource buried at the depth of more than 1000 m accounts for about 53% of the total coal resource in China (Peng 2008).The mining at such significant depth is often associated with complex and harsh conditions such as high stress, high ground temperature, high karst water pressure and severe mining disturbance, resulting in high potential of coal and gas.

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.
