An Introduction To Surface Mining

Mining is merely defined as digging in the ground to find something of use. The process has been a part of life since antiquity, and is still the backbone of the world''s commerce and production. Mining could be classified in two forms: mining at the earth''s surface (surface mining) and mining underground (subsurface mining).

(in Russian, shakhta), a mining enterprise that extracts minerals by underground methods and ships them to a consumer or an ore-enrichment plant.An underground mine includes both surface structures—for example, headframes, headhouses, and storehouses—and all the underground mining excavations that are used to work a deposit within a mine area.

COAL EXTRACTION AND PROCESSING

There are two main methods used in coal extraction: surface mining (above the ground) and subsurface mining (below the ground). Location is the biggest factor in determining what method will be used. Normally surface mining occurs west of the Mississippi river and subsurface occurs to the east.
