11.G. MINING

Mining water use includes water used for the extraction and on-site processing of naturally occurring minerals including coal, ores, petroleum, and natural gas. Basically, minerals are broken up in the earth and transported to the surface where it is crushed, ground, and separated from the host rock material (fig. 7).

Open pit mines can be used in coal mining, and they are used extensively in hard rock mining for ores such as metal ores, copper, gold, iron, aluminum, and many minerals. In a open pit coal mine, the pit bottom would be the bottom mined coal seam elevation, since it is usually feasible to extract multiple seams when surface mining coal.

Environmental Risks of Mining

Hardrock mining exposes rock that has lain unexposed for geological eras. When crushed, these rocks expose radioactive elements, asbestos-like minerals, and metallic dust. During separation, residual rock slurries, which are mixtures of pulverized rock and liquid, are produced as tailings, toxic and radioactive elements from these liquids can leak into bedrock if not properly contained.

How Underground Mining Works

There are hard-rock underground mines, and there are soft-rock underground mines. Coal deposits, for instance, live in relatively soft sedimentary rock. Gold deposits live in igneous or metamorphic rock, which is relatively hard, as do diamonds, copper, silver, nickel and zinc [source: Great Mining].

Coal mining

Methane released from the coal seam and surrounding rock strata during mining can present a high risk of explosion at concentrations in air of 5-15%. Techniques have been developed to eliminate and/or dilute methane emissions both prior to and during mining and this has helped to significantly reduce methane related explosions in underground mines.
