Is split rock rocky massif where we find it

_ Load : 

Is collect rock boot floor, and his transfer to a means of transport.

_ Transport: 

Is the operation which moves or pulled up outside the mine.

Once down, enters a labyrinth that more than forty kilometers from the mines of Súria and Sallent and where heavy lorries. The most spectacular are the miners, drilling machines that can boot a ton of ore walls every minute. The miners work with electricity and have clearly improved the rate of extraction compared to the explosives that were used before. Each year drawn more than a million and a half tons of material from underground Catalan. Of these, 700,000 tons of potassium chloride. 

A worker colored stripes on the walls of the mine of Iberpotash geologist, explains that correspond to different types of minerals, in different stages of evaporation are deposited in layers over time, the first soluble and less about that stayed longer in solution. 

Other person, indicates that the mines are located more than 600 meters below sea level because in this area the package is compact enough salt and galleries can last longer. However, where the potash is removed at a higher level. Since there are saline packet access by creating so-called "fronts of attack": galleries that start extracting potassium salt. Then the mineral leads to trucks or conveyors that carry potash to the shaft, and from there to the outside.
