Highwall — The unexcavated face of exposed overburden and coal in a surface mine or in a face or bank on the uphill side of a contour mine excavation. Highwall miner — A highwall mining system consists of a remotely controlled continuous miner which extracts coal and conveys it via augers, belt or chain conveyors to the outside. The cut is ...

ABSTRACT Fatalities caused by highwall/spoilbank failure in the
mining with highwall mining being conducted after economical limits of the pits are reached. The active mining is 40 kilometres long with reserves covering 150-km of strike length. The width of active mining is up to 3 kilometres. Mining is complicated by the range in geologic condit ions in strata types and the steep dips (up to 20 degrees).
"This system incorporates all of our latest technologies relative to steep dip mining while preserving the core designs that have created the ADDCAR legacy of reliability and productivity," said Johnny Sturgill, President ADDCAR. The main components included with the system are: Launch Vehicle Foot Print 95 ft .

VENTILATION OF HIGHWALL MINING TO CONTROL METHANE CONCENTRATION AT THE MOURA MINE | PAGE i Abstract Methane is a highly explosive gas released during coal mining that presents an imminent problem when mixed with oxygen in regard to maintaining safe working conditions in underground and highwall mines.
Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef or placer deposit.These deposits form a mineralized package that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay.
Highwall mining can produce thousands of tons of coal in contour-strip operations with narrow benches, previously mined areas, trench mine applications and steep-dip seams with controlled water-inflow pump system and/or a gas (inert) venting system.

Steep Dip; Cascading Conveyor Cars. The signature of ADDCAR Highwall Mining is the unique Cascading Conveyor system that uses open conveyors to feed coal from the miner to the stacker conveyor without increasing fines. As the miner works its way into the seam, an end loader places Conveyor Cars onto the launch vehicle, where they're hooked up ...
two main highwall mining systems currently used in Australia are the Addcar Highwall Mining system and the Auger system. Previously, the Moura Mine's highwall mining operation used the Addcar Steep Dip Highwall Mining system, a modified Mining Technologies Addcar Highwall Mining system with the remote controlled Joy 12CM12B continuous miner.

Westmoreland, ADDCAR, and AAI are currently in the process of designing another area for highwall mining production, which should be ready to begin production later this year. 5. Conclusions. The restrictions imposed by steep-dip mining substantially reduce production and recovery as compared to flat-seam mining.
The key to quality and productivity is to keep the miner operating in the seam. No system beats the accuracy of Addcar's navigation. Your operator will know where they are heading exactly.

The technology used by the ADDCAR Group for highwall mining is advanced making ADDCAR a global leader. Some of the technology applied to highwall mining includes: Lateral Guidance: Addcar highwall systems utilises three pairs of ring laser gyroscopes and accelerometers to monitor the heading, pitch, and roll of the continuous miner.
