Mining Operation PROSPECTION Performed to discover zones with the greatest concentration of coal deposits. WILDLIFE RESCUE AND RELOCATION Species are inventoried for subsequent rescue and relocation to suitable areas. DRILLING AND BLASTING Deep holes are drilled were the emulsion is disposed in order to blast the waste rocks into fragments. Topsoil is removed and stored in soil banks to be used in land reclamation. TOPSOIL REMOVAL REMOVAL, LOADING AND TRANSPORT OF COAL Once the coal cloaks are exposed, the mining process begins and the coal is loaded onto 190-tonne trucks. REMOVAL OF WASTE ROCK Shovels remove the waste rock and load it onto 240- and 320-tonne trucks that take it to dump sites or to backfill areas for land reclamation. Mining equipment to humidify haul roads The water used is not suitable for human or animal consumption or crop irrigation. WATER TANKER 65% 35% of the coal is taken directly to the crushing hoppers. of the coal is stockpiled. CRUSHING AND/OR STOCKPILING At the plants, the crushing hoppers receive the coal and crush it. It is then transported via conveyor belts to silos to be loaded later onto the rail wagons. LOADING THE TRAIN, WETTING AND COMPACTING Each wagon's load is wetted, compacted and levelled as a control measure along the 150 km train journey from the Mine to Puerto Bolívar. DIRECT-LOADING SYSTEM The coal is reclaimed and sent to the direct shiploaders, which place the coal directly in the holds of the coal ships, which then set sail to various ports worldwide. The coal port receives ships up to 180.000 tons. Since 1985, before it was a legal requirement in Colombia, Cerrejon owns a direct shiploader system. In 2014, we inaugurate the second direct shiploader wich allows to fill two ship warehouse at the same time.

The largest fossil snake in the world

During coal extraction, we have uncovered interesting palaeontological finds, including fossils of turtle shells and of giant leaves, which indicate this zone was a tropical forest over 55 million years ago. The most interesting discovery was the Titanoboa cerrejonensis a giant snake that ever existed in the earth.
