Extracting salt from mines

Most salt mines operate underground but in salt deserts the rock salt is also mined at the surface. Two main methods of extracting rock salt are used in underground mining: Cut and blast mining consists in cutting slots at the base of the rock face. A series of carefully sited holes are drilled and then charged with explosives to blast the rock.

Rock salt was first mined in Hutchinson in 1888, using solution mining (a mining method that pumps water down wells to dissolve the salt), when two wells and a salt factory were put into operation. By 1891, underground mines (using a mining method similar to underground coal mining) produced salt at Lyons, Kingman, and Kanopolis.
