used highwall mining equipment for sale

Highwall mining is a method of mining that originated from auger mining. The method differs in that continuous miners, rather than augers, are used to bore an entry adjacent to the coal seam of a highwall left behind in an open pit mine after excavation has been completed. Screw conveyors positioned behind the continuous miner haul the cut coal from deep within the seam up to an outside stockpiling area where it is then transported away.

Another primary difference in a highwall mining operation is that it is carried out by remote control at the surface where an operator located in a cabin uses a television camera to monitor and control the progress of the continuous miner machine.

Highwall Mining Technique

Highwall Mining Process

When the cost of excavating an open-pit mine is no longer economically feasible, highwall mining may be deployed before the entire operation is taken underground.
Highwall mining as a first option presents many advantages to underground mining because it is more cost-effective and involves less lead-time. The process of mining a highwall with continuous miners is proven to also be much safer since operations are carried out exclusively by remote control and require fewer personnel than underground mining.

Highwall mining at the surface produces the same amount of output as mining underground might. With highwall mining, smaller blocks of coal can also be accessed and operations are facilitated around geological impediments or structures that otherwise impinge upon coal production.
