Of the11 potash minesin Saskatchewan,nineare conventional underground mining operations, which require underground equipment and personnel. The other two are solution mines, which involve pumping heated water through the ore body to dissolve the potash and pumping the resultant brine solution to a refinery for extraction.

Conventional miningusually occurs around 1,000 metres below the surface. Solutionminingcan access potash reserves at depths exceeding 1,600 metres below the earths' surface. The majority of Saskatchewan potash is mined by theconventional miningmethod, where largeminingmachines are used to extract the ore by cutting tunnels into the ore body.

The U.S. coal industry serves a vital role in the nation’s economy by producing fuel for more than half of its electricity. Despite the industry’s importance, industry financial data for 2005—the strongest year for the coal industry in recent years—shows that it is a relatively small industry with revenues totaling $20 billion to $25 billion and net income between $1 billion and $2 ...

Surfaceminingis used to produce most of the coal in the U.S. because it is less expensive than undergroundmining. Surfaceminingcan be used when the coal is buried less than 200 feet underground. In surfacemining, giant machines remove the top-soil and layers of rock to expose large beds of coal. Once theminingis finished, the dirt and ...

Open-pitminingmethods are applicable tominingore deposits that apex at or near the surface. If the deposit apexes below the surface, the overburden and barren capping overlying the ore must be removed in advance of open-pitmining. The removal of this material is known as stripping. The stripping-pit limits must be extended beyond the limits of the ore pit to provide a bench, and the pit ...

LONGWALLMININGOverview. In the method of secondary extraction known as longwallmininga relatively longminingface (typically in the range 100 to 300m but may be longer) is created by driving a roadway at right angles between two roadways that form the sides of the longwall block, with one rib of this new roadway forming the longwall face.
