What Is a Salt Mine?

Salt mine (halite ore; salt mine) is the general name of NaCl, also known as "salt" and "sodium salt". Its representative mineral is stone salt. The raw materials of salt can be divided into 4 categories: sea salt, lake salt, well salt and mineral salt. The salt produced by using seawater as raw material is called "sea salt"; the salt produced by mining modern salt lake ore processing is called "lake salt"; and the salt produced by processing the shallow surface or underground natural brine using the well drilling method is called It is called "well salt"; the salt produced by mining ancient rock salt deposits is called "mineral salt". Because rock salt deposits sometimes coexist with natural brine salt mines, and the advent of water-soluble drilling methods for mining rock salt deposits, there is a collective name for "well salt" and "mine salt"-"well salt", or "mine salt" .

Salt mine

Salt mine ( halite ore; salt mine ) is the general name of NaCl, also known as "salt", "

Salt is a necessity for human life and a basic raw material for the chemical industry. It is also widely used in agriculture and other industries.

Table salt is an indispensable substance to maintain the normal development of the human body. Adults generally contain about 90 g of sodium and 85 g of chlorine, most of which are stored in body fluids. Contraction of muscle by sodium,

Our country

China is one of the countries with the longest history of producing salt. According to legend

Tens of thousands of years ago, some places were free in the ocean or inland. Later, due to the dry climate and high temperature, seawater or lake water evaporated and crystallized into salt, and then changed by sea and land, turning the sea basin and inland lake into land. The salt in the sea basin gathered together to form a salt mine. Onshore salt mines are mainly stone salt. Stone salt is the common salt we usually eat. Because it is produced in mountain rocks, it is also called rock salt. The chemical composition of stone salt is sodium chloride. Its crystals are cube-shaped and the block is large and transparent, so the ancients called it bright salt, crystal salt, jade salt, and white salt.

Wieliczka Salt Mine

Huaian City, Jiangsu Province has the largest salt mine in the world, and it has become China's salt capital. The Huaian Mine was discovered during drilling in 1956 by Jiangsu Petroleum Exploration Command and Jiangsu Coalfield Geological Exploration Third Geological Team. The center is located in Zhuqiao Town, Chuzhou District, Huaian City. From 1978 to 1985, the proven reserves were 250 billion tons, and the ore-bearing stratum was the Mesozoic Cretaceous Pukou Formation (K2p). The roof burial depth was 800-900 meters, the marginal ore roof burials were 600-700 meters, and the salt-bearing strata were up to 1,400. 1800 meters, the average thickness of the salt layer is 347.41 meters, the salt content of the mineral layer is generally 50 60%, and the salt layer is of high grade. The thickness of salt-bearing systems above 1500 meters is 967 meters; the cumulative thickness of salt deposits is 377 meters, and the reserves are 101.805 billion tons. Wanxian, known as the "gateway to the east of Sichuan," Qianjiang County, Hubei Province, and Zigong, Sichuan Province, are rich in stone and salt reserves.

The 120-meter-deep part of the Wieliczka Salt Mine in Poland has been mined, and underground salt crystals have been completed

Wieliczka Salt Mine Museum

Palace and Salt Mine Museum. Three-dimensional animals and portraits are carved on the surrounding rock walls. Under the illumination of the lights, they are magnificent and magnificent, making people feel like they are in the "Crystal Palace". Every year, 700,000 tourists go to explore. There is also a special salt well hospital here, which allows patients to breathe salty air, which can treat asthma and lung diseases, and the effect is the highest for children. What's more interesting is that the large crystalline stone salt there is also surrounded by marine plants and corals. This proves that this area turned out to be an ancient sea.

The Carl Salt Mine in Texas, USA, is both a mine producing salt and its space is also used as an underground warehouse. This mine has been mined for almost 60 years. At a depth of 200 meters from the ground, there are 15,000 rooms on both sides of the abandoned tunnel, containing valuables and documents.
