Almost two decades of operation, CK has signed a number of contracts, expanding our coal mining expertise into non-coal mining and construction.


As one of Indonesia’s leading coal mining contractors, we offer a competitive advantage through our ability to provide complete mining solutions, engineering and project management. We specialized in survey and exploration, modeling (topography and geology), mine design, drilling and blasting, overburden removal, mine extraction, transportation, supporting facilities construction, storage and processing facilities management, and mine rehabilitation. In every project, we place high concern on efficiency, maximizing utilization with high productivity in line with good mining practices. The success of production in each of our project is always accompanied with actions to ensure consistent zero-level accident.



We maintain the highest quality equipment fleet to meet our clients’ needs. Our main equipment fleet is fully supported by our group company, PT Trakindo Utama as supplier and distributor of Caterpillar Equipment in Indonesia. We have sufficient capacity within our owned equipment fleet to deliver high productivity services for any operating mine or mine development project.



Since 2013 CK has expanded its businesses into construction services, which exist to further expand our business network and the opportunity to provide complete solutions to all clients in mining, oil and gas, as well as infrastructure industry.

Our construction projects which currently focus in civil infrastructures consist of:

  • Earthworks and site preparation
