A number of modifications were made to the standard highwall mining system to allow it to work at the 20° slope present at Kemmerer. These modification were primarily related to strengthening components to handle the weight of the miner and train of conveyor cars. Additionally, the cutter head was replaced with a higher power, heavy …

Mining. Highwall mining is a hybrid of surface and underground mining technologies that is used to recover coal that is otherwise uneconomical due to: Increasing open – cut strip ratios. Reaching pit limits with available coal in the barrier pillars. Protected surface features (e.g. rivers, streams, archaeology) Inadequate panel length for a ...
In these mining systems, a continuous miner or an auger machine is primarily used to extract coal from the highwalls (See Figures 6 and 7). Recently another systems such as superior highwall miners have been introduced in the US (Highwall systems, 2006). Figure 8 shows the classification of highwall mining systems.

Highwall Safety. 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 ...
Highwall mining differs from continuous mining in that it is carried out by remote control at the surface. Here, an operator, usually located in a cabin, uses a television monitor to control the progress of the continuous miner machine. Highwall mining is often used when excavating an open-pit mine becomes too expensive.
