At the bottom of an ancient sea

For millions of years nature has shaped these beautiful patterns that are now mined and used in various fields of industry, agriculture and the national economy.





Initially, the mines used only rail transport, especially when driving development workings or reservoirs with a complex geological structure.



Currently working out of potash deposits maintained with the help of a panel system combines.





To resolve the panels between them are wide panel recessed drift where the conveyor is installed. Drift traversed three or four stroke harvester, it provides a sufficient width to accommodate the drift conveyor, ventilation and technology directions. Roofs with special screw rods secured to prevent delamination and stabbing "cakes". The rods are installed special mechanical oborschikom roof.



The conveyor drift traversed by 4 stroke combine and overlap in descending order. Left by a small pillar mezhhodovoy.



In order to minimize downtime during the combine movement, loaded or empty wagon from the combine to the point of discharge (conveyor or rudospusknaya well), using special transfer bunker, which accumulates mined salt combine.



Belt conveyors are laid in the workings of the underlying rock salt.



Small lake of saturated brine. The density of the dissolved salt in it is so high that the salt to dissolve it can no longer.



Drive at the junction of the two conveyors, alarm system and fire extinguishing system.



Gob filled with dry salt or soleothodami of penetration development workings.



Filling is carried out either scraper winch, or by self-propelled carriages.



Exhaust and stub generation often contain hazardous gases - methane, hydrogen sulfide, radon, etc.



Gases are also allocated in the development and formation, they are contained in the microcracks, and in the salt crystals.



Haulage drift with rudospusknymi wells (winze).



The top layer mineral product descends into the well and through the hopper enters the conveyor.



Trunk pipelines with capacity up to 1000 t / h to deliver the extracted salt mine shaft, where it is already in the skip rises to the surface.



Drive conveyor.





To move people and equipment between the layers used rebelling salable and transport ramps.





In the transport roadway you deliver equipment and workers to work off the panels.



In parallel, transport roadway passed airway for ventilation panels.



The drifts are sometimes found quite a large puddle of brine. Top swim growths of crystals of salt.



Passing these areas better footwear - rassolohodah.



On this small tour ends and we climb back to the surface, to wash off the salt of the earth.
