Mining is the extraction of valuable minerals or other geological materials from the earth, usually from an orebody, 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.
Technical considerations for TBM tunneling for mining projects Dean Brox Dean Brox Consulting, Ltd., Vancouver, Canada Abstract Tunnel boring machines (TBMs) have been used for the construction of various tunnels for mining projects for the purpose of access, conveyance of ore and waste, drainage, exploration, water supply and water diversion.

Artisanal mining in South Africa probably has a long history, but this has not been documented. For Zimbabwe, Roger Summers has mapped extensive pre-colonial mines, prospecting trenches, and early processing sites, but this has so far not been done for South Africa. Violence is a constant problem in the artisanal mining sector.
As the first contractor in the world to mine hard rock with a 30-foot diameter Tunnel Boring Machine (TBM), Kenny has highly automated the entire tunneling process, reducing tunneling costs. In predominantly urban applications, tunnel boring is a quick, safe and cost-effective alternative to laying surface rails and roads.
Whether and when deposits are profitable also depends on the efficiency of the technology used to extract ore deposits. We have therefore used our expertise in mechanized tunnelling to develop innovative machine concepts for a variety of applications in mining.
