What is a salt mine?
Salt Mine is a dug area on or below the Earth's surface created to extract this sought -after mineral. This widely used crystalline mineral varies in color and can be found in seawater or on the ground. Salt needs to be mined to get into underground deposits. The salt mine has shafts for input and output and usually consists of rooms created in a chessboard sample. Extraction and processing include free crystal blasting, then crushed them several times before sending them to the surface for further processing.
also referred to as sodium chloride, salt is a mineral with cubic crystalline production. Its color ranges from grayish to transparent or freezing white to pink, depending on its purity and mineral composition of the superior rock. It is generally used for industrial applications and food. Deposits of the Earth on the Earth are the result of the last evaporation of water bodies. Salt deposits can also be found underground, domes or veins between layers of sedimentary mountainsniny. In recent cases, extraction requires a salt mine.
As well as coal operations, the salt mine uses shafts to allow staff, supplies and mined rock under and above the ground. One shaft is designed for humans and the other for mined salt and supplies that are pulled and carefully reduced down. The shafts also provide fresh air for work miners. The mining rooms are usually formed in the chessboard pattern, so part of the salt, about 35 to 55 percent, is left in the form of columns. These offer structural support of the mine.
The mining process is working demanding and starting with cutting the horizontal slot under the salt wall, which eventually falls. Ana side holes are drilled 10 feet (about 3 m) or deeper and dynamite is placed inside. Explosives are issued remotely when there is no staff in the salt mine and the rock breaks and falls on the floor. Miners gather mineral andIt travels along the transport belt where it is crushed several times before it is sent to the surface. Salt is then a proposal with several screens and is stored for packaging and transport.
until the industrial revolution, salt was rare and mining was considered extremely dangerous and expensive. Before this time, the extraction of salt was mainly carried out slaves, who were actually traded for a commodity in places such as ancient Greece. Modern salt mine was developed after creating an engine with internal combustion.
