Cerrejón Coal Mine - La Guajira, Colombia

Cerrejón is a large open-pit coal mine in Colombia. It is located in the southeast of the department of La Guajira, close to the border with Venezuela. The coal mine is situated in the northeastern part of the Cesar-Ranchería Basin, the basin of the Ranchería River, between the Sierra Nevada de Santa Marta in the west and the Serranía del Perijá to the southeast. At Cerrejón, low-ash, low-sulphur bituminous coal from the Cerrejón Formation is excavated. The mine is one of the largest of its type, the largest in Latin America and the tenth biggest in the world. Cerrejón extends over 690 square kilometres (270 sq mi). It is divided into three sections, North Zone, Central Zone and South Zone. Total proven reserves are estimated at 503 megatonnes. In 2016, the mine produced 32,683,315 tonnes (32,167,132 long tons; 36,027,188 short tons).


From 1985 to 2011, the coal mine of the Cerrejón, produced 508.8 million tonnes of coal and generated US$2,006 million in royalties. In 2011 alone, sales generated US$336.60 million for the country as a whole and the region of La Guajira.

By the end of 2011, the mine of the Cerrejón, had reached a historical production figure of 32.03 million tonnes to the following markets: Europe (58%), the Mediterranean and Asia (21%), Central and South America (12%), and North America (9%).

These external sales represent 40% of Colombia’s coal sales and 4.6% of global coal sales.

Carbones del Cerrejón’s directly employed workforce numbers 5,373 workers (62% from La Guajira, 28% from other parts of the Caribbean coast, and 10% from the rest of the country).

In addition, a further 4,497 workers are employed indirectly through contractor firms for the operation.

Carbones del Cerrejón has a mining fleet comprising 493 pieces of equipment: 258 trucks with a load capacity of 190, 240, and 320 tonnes, 50 hydraulic shovels, and 185 pieces of auxiliary equipment.

A 320 tonnes (310 long tons; 350 short tons) truck can haul a load equivalent to approximately 10 tractor trailers. In Colombia, a tractor trailer hauls 30 to 35 tonnes.

A P&H 2800XPC shovel has a load capacity equivalent to the weight of 40 automobiles, that is, approximately 63.5 tonnes.

A PC8000 shovel can manage a load equivalent to 50 automobiles (approximately 75.3 tonnes (74.1 long tons; 83.0 short tons)).
