Undercutting
The extraction process begins with undercutting the mine walls level with the floor. A self-propelled undercutter carves a massive channel at the base of the deposit and across the entire room. This channel allows for a more efficient explosive blast and also helps create a smooth mine floor.
Drilling
Once the mine wall is undercut a special drilling machine bores small holes into the face of the salt. Then miners will prime these holes with explosive materials and prepare to start blasting.
Blasting
Miners ignite the explosives, creating a blast that dislodges 800 to 900 tons of rock salt in less than three seconds. The depth of the mine and cushion of the overburden absorbs the blast vibrations, preventing any surface damage to immediate and surrounding areas.
Loading
Huge front-end loaders transport the blasted rock salt to the primary crusher. Loaders dump their loads of salt into a powerful spinning crusher, where large pieces are quickly crushed and screened down to small pieces. The salt is then transported to the hoisting shaft where skip hoists bring the loads to the surface in a matter of seconds.
Transportation
Upon reaching the surface, the salt is stored here at the mine in our huge stockpile where it is loaded and sent out to customers by rail car or by truck.
