Based upon a recent investigation of truck vs. rail haulage in bituminous-coal mines, Toenges and Jones conclude that with equipment in its present stage of development and within the range of conditions studied, for a new mine a dual haulage system would effect a saving in transportation cost if the round-trip haul exceeds 2.7 miles.
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.
