Highwall mining has become a widely applied method in surface mining. It is commonly used alone or in conjunction with contour or slot mining. It provides 800 to 1,200 ft of additional recovery when, in contour mining, the economic stripping ratio is reached or, in slot mining, when surface access to a reserve is limited.

Reasonable coal pillar design and remote control

Highwall mining is a technique to obtain additional coal recovery after the economic strip limit is reached in surface mining. It involves the remote deployment of a continuous miner in openings beneath the final highwall with no personnel entry. Many candidate areas for highwall mining have thick and steeply dipping seams.
