Highwall Miner. Highwall mining is an efficient, proven and durable method for mining coal from exposed horizontal seams — producing an average of 110 000 tonnes (120,000 tons) of coal per month in coal seams up to 300 m (1,000 ft) in seams dipping up to 8 degrees — recovering up to 70 percent of in-place coal.

The highwall miner can advance 1200' under the highwall compared to a typical 300' for an auger. Recovery rates improve from roughly 30% for an auger to near 50% for a highwall miner. The highwall miner can adapt more easily to varying seam thickness or other changes under the highwall. Its production rate can be much higher than an auger ...

Highwall mining is an innovative technology that extracts coal with less expenditure and in a completely safe manner. Our Highwall Miners are unmanned cutters that are driven underground to a highwall of an exposed seam. The Highwall Miner makes cuts in the coal seam that then bring the coal back to the entry and pile it up.
