Jun 03, 2008· The highwall mining system is fully adapted to work in dipping conditions, and is supplied with a SHM- Joy 14CM15 cutterhead. It is also equipped with a newly developed steep-dip mining package to enable the highwall miner to work in seams with more than a 12 degree dip.
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.
In mining: Blasthole stoping. When the dip of a deposit is steep (greater than about 55°), ore and waste strong, ore boundaries regular, and the deposit relatively thick, a system called blasthole stoping is used. A drift is driven along the bottom of the ore body, and this is eventually enlarged. Read More; relationship to strike. In strike

Figure 4. Types of Highwall Mining (Hansen and Kelly, 2014). Traditionally highwall miners use either an auger system or a continuous miner to extract coal from the highwall. Other forms of highwall mining have been undertaken by producers including Archveyor highwall systems and BHP's steep dip continuous highwall miner
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.
Nov 25, 2003· A highwall mining system of the type wherein multiple conveyor cars are connected together to form a conveyor train which extends into a seam being mined by a mechanical miner located at the inner end of the conveyor train is capable of effective operation in steep dip seams, e.g. up to about 30°, and is constructed so that it can be quickly disassembled, moved, and reassembled and .
