Interpretation of Gravity Monitoring Data on Geotechnical

 · The Verkhnekamskoye potassium salt deposit located in the Perm Krai is the main source of raw materials for the potash industry in Russia. The penetration of underground waters into the shafts of the mine which is situated beneath the industrial zone and residential quarters of the city of Berezniki led to the flooding of the mine with subsequent collapsing of the earth s surface.

Halite salt The mineral Halite information and pictures

Halite also forms from evaporation at salt springs where saline water comes out of the ground in a salt deposit and precipitates as rounded globular masses. In some underground salt deposits such as Texas and Louisiana salt is pushed upwards by an underground force through soft ground and forms arched structures known as salt domes. These deposits are also important sources of salt mining operations
