Highwall mining relies on machinery to collect ores from a “highwall”, or an unmined wall with overburden and exposed minerals and ores. Usually, highwalls are found at the edges of quarries and pit mines, and enable miners to retrieve ore from a wall that would otherwise be too expensive to clear of overburden in order to reach the ore.
The Highwall mining system uses a launch vehicle, continuous miner and series of Addcars™ to extract coal from an exposed highwall. Unlike conventional underground operations no personnel enter the underground operations. All equipment is operated remotely from the surface launch facility.
