Highwall miners link underground and surface mining operations by extracting coal from exposed horizontal seams in open-pit mines. This is done via a mobile system that contains a continuous miner controlled from the operator's cabin, a retractable conveyance system, and a vertical conveyor that handles and stacks the coal for transport.. The point at which the cost to remove the overburden
Continuous Miner. The ADDCAR system allows you to select the Miner (from the major OEM’s) that best matches your seam conditions. ADDCAR has worked closely with the major OEMs and both parties are familiar with the modifications that must be made on a standard continuous miner to adapt it for highwall mining.

Highwall stability is essential for open-cut mining.In these particular projects, otherwise known as open-pit mining, employs a technique in which rock and minerals are extracted from a borrow pit, or sandbox.For long-term highwall performance, the substance properties that makeup mining sites—or more specifically, the rocks and minerals found within the borrow—should be carefully examined
The highwall miner operator uses a programmable logic controller (PLC) to set the mining parameters that keep the cutter module within the coal seam. “By monitoring the amperage of the cutting motors, the operator can lower or raise the set-point of the cutting drum to avoid cutting floor or roof rock.
