during surface mining. The auger mining system was initially developed in the early 1940s in the United States of America. High wall mining is a method of recovering coal from seam exposed either by mechanical excavation methods or natural erosions. This is usually associated with strip-mining (opencast) where the stripping ratio is high and uneconomical to mine using the opencast mining ...

Coal Augering Services - Mining Technology Mining News ...

Auger mining operations drill a series of parallel holes perpendicular to the highwall, leaving adequately sized pillars between holes to maintain the stability of the highwall and overlying surface area. The technique is also commonly used to recover coal beneath surface features which limit surface mining, such as rivers and roads.
