In the larger mines sinking takes place under a working shaft, the shaft being bulkheaded under the hoisting compartments and several hundred feet above under the auxiliary compartments. A lining of 2-in. or 3-in. plank is run, separating the auxiliary and main hoisting shafts between these two bulkheads.
Shaft Mining: Shaft mining is a form of underground mining where shafts are pushed vertically from top to bottom to excavate the ores and minerals. It is also called shaft sinking. It is best suited for concentrated minerals such as iron, coal, etc. which can be found at the depth of the earth's surface. It is found mostly all over the world.

Solution Mining: Solution mining can substitute for conventional shaft mining in potash deposits that occur below 3,000 feet. Vertical pipes are drilled to supply water to the ore zone and a return pipe brings the saturated brine to the surface where it is evaporated in surface ponds leaving potash.
