Mining and mineral resources have been an important part in the history of civilizations and the Retsof Salt Mine was once one of the largest operations in underground salt mining in the world. The mine produced millions of tons of rock salt throughout its one hundred and ten year lifetime up to its collapse and flooding in 1994.
IMO, UG placer mining cannot compete with bulk, low-grade surface mining or hard-rock, high-grade UG mining but its an interesting idea Roadheaders have gotten stronger, but still not passing 150 MPa. A solution mine was proposed in AK, basically high-pressure injection wells and pumps to mine pods of an extensive horizontal pay layer on ...

Mining - Mining - Underground mining When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for each ton of material mined, are much higher underground than on
Nov 27, 2007 Salt is generally produced one of three ways deep-shaft mining, solution mining or solar evaporation. Deep-shaft mining is much like mining for any other mineral. Typically, the salt exists as deposits in ancient underground seabeds, which became buried through tectonic changes over thousands of years.
Underground mines of all sizes require a formal, planned ventilation system to deliver fresh air to all working places. Mine ventilation is the process of supplying sufficient fresh air to the UG workings to achieve these purposes, ensuring proper distribution amp use of the air, and controlling the return to surface of contaminated air.
Underground mines are the alternative to surface mines. Surface mines excavate from the top down, a method that can become inefficient at depths greater than about 200 feet 60 meters sources Illinois Coal Association, De Beers.Undergrounds coal mines can drive 2,500 feet 750 meters into the Earth and other types even deeper -- uranium mines can reach 6,500 feet, or 2 kilometers.
Mining is the extraction of valuable minerals or other geological materials from the earth from an orebody, lode, vein, seam, or reef, which forms the mineralized package of economic interest to the miner.. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, dimension stone, rock salt, potash, gravel, and clay. Mining is required to obtain any material that cannot ...
The geology of the Great Lakes salt mining area consists of sedimentary deposits of shale, limestone, sandstone, dolomite, gypsum, anhydrite, and rock salt halite. These formations within the mining area are relatively continuous and generally undisturbed by faults or other forms of sharp ground movements.
Depth also determines the electricity costs of operation, ventilation, and lifting salt, equipment, people, and water in and out of the mine. Most of the rock salt produced in the United States is produced by traditional room and pillar mining - a mining method that is widely employed in mining for coal. This involves sending people and ...
