Colombia is rich of minerals and energy resources. It has the largest coal reserves in Latin America, and is second to Brazil in hydroelectric potential.Colombia's coal output has increased consistently from 4 million tons in 1981 to 65.6 million tons in 2006, when it contributed 1.4 percent of the world's coal production.
In 2006 Colombia accounted for 81 percent of the total coal production in Central and South America. Furthermore, 94 percent of Colombia's coal is of very good quality and is classified as hard, with high heat-generating capacity.The largest coal mines—and the ones that generate the most exports—are located in the north of the country, in the departments of La Guajira and Cesar.
Coal production plays important role in Colombia economy development. Colombia has more than seven billion tons of coal in measured reserves and with only 73 million tons being mined in 2009, there is significant opportunity for the development of the coal industry inColombia. The major Colombian coal producers - Cerrejon, Drummond and Prodeco - are expected to see a doubling of their capacity in the coming years. This means coal will continue to play a significant role in Colombia's future economic growth. At present, more than 90% of Colombia's coal is exported and with coal demand remaining strong worldwide, especially with the continued economic expansion in China, coal will play a major role in Colombia's future export income.
Coal production line also known as coalbeneficiation plant or coal washing plant. It refers to the processing operation of run-of-mine coal to improve coalquality and to enhance its suitability forfinal applications.The coal production line design depends on the properties ofthe coal and its final use. It may requireonly simple crushing operation or it may need to gothrough a complex production process toreduce impurities.
To remove impurities, the raw run-of-mine coalis crushed by crushing plant and then screened and separated into various sizefractions. Larger material is usually processed by dense medium separation. In thisprocess, the coal is separated from otherimpurities by being floated in a tank containinga liquid of specific gravity, usually asuspension of finely ground magnetite. As thecoal is lighter, it floats and can be separatedoff, while heavier rock and other impuritiessink and is removed as waste.

Coal can be mined by open pit and underground mining method according to deposit properties. When coal seams are near the surface, it may be economical to extract the coal using open cut mining methods. Open cast coal mining recovers a greater proportion of the coal deposit than underground methods, as more of the coal seams in the strata may be exploited.
Most coal seams are too deep underground for opencast mining and require underground mining, a method that currently accounts for about 60 percent of world coal production. In deep mining, the room and pillar or board and pillar method progresses along the seam, while pillars and timber are left standing to support the mine roof.
SBM provides high quality coal mining equipment for sale. Mining equipment involved in coal mining plant includes drilling and blasting machine, quarry machine, extraction plant, mobile crushing plant, coal preparation equipment, coal sieving equipment etc.The selection of the processing flow sheet is probably the single most important step in the plant design process.
