Highwall mining Britannica

Highwall mining is an adaptation of auger mining. Instead of an auger hole, an entry into the coal seam is made by a continuous miner, remotely operated from a cabin at the surface. The cut coal is transported by conveyors behind the miner to theCoal 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. Contract auger mining can be used by coal mine operators whoCoal Mining and the Highwall Method OilPrice,26/11/2010· Augered seams in a highwall (Bundy Augur) The coal auger is not dissimilar in shape to the auger used in making large holes in wood, or which might be used to drill large vertical surface holesDesign of Auger highwall mining slideshare.net,7/1/2018· Highwall mining method, which is considered as the semi surface-underground mining operation, was originally developed in the early 1940s in the US. It is suitable to excavate this remaining coal.

In the last three years highwall mining in Australia has taken a backseat with most of the fleet of about five mining systems standing idle. This is largely a factor of the coal price and the exchange rate which has extended the life of open-cut

Auger mining is a 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(PDF) Highwall Mining: Design Methodology, Safety and,1/9/2014· 1,200 ft, the highwall mining method is preferred over auger mining.

Currently, there may be up to 60 highwall mining systems and as many as 150 auger mining systems operating in the nation’s surface coal mines. Recent estimates suggest that upwards of 45 million clean tons representing about 4% of total U.S. coal production comes from these methods (1Highwall Mining Mitigation Specialised Geo Pty Ltd,High Wall Stabilisation.

29/4/2016· Highwall mining systems can sometimes be the final mining method used in open cut mines, or it can serve as a means of transition, with low capital cost, from surface mining to underground mining. From the results of a series of laboratory tests and numerical analyses, stability of openings/pillars in the auger mining system is higher than that in CHM. The pillar strength for circular (PDF) Application of highwall mining system in weak,highwall auger mining in Australia.
