Coal mining in Chile
From Wikipedia, the free encyclopedia
In Chile, coal mining is restricted to a few places located in its southern half. Energy originating from coal stands for 11,6% of Chile's electricity consumption.[1] Currently the country is not considered a major producer of coal.[2]
The three zones of mining are Zona Central Sur (36–38° S), Zona Sur[upper-alpha 1] (39–42° S) and Zona Austral[upper-alpha 2] (51–54° S) in southernmost Chile.[1][3] Most of the coal resources of Chile lie in Zona Austral at southernmost Chile.[4]
