PT Freeport Indonesia (PTFI) is a mineral mining company affiliated with Freeport-McMoRan (FCX) and Mining Industry Indonesia (MIND ID). PTFI mines and processes ore to produce concentrates containing copper, gold, and silver. We market these concentrates globally, with a primary focus on domestic copper smelter PT Smelting. Our operations are based in the remote highlands of the Sudirman Mountains, Mimika Regency, Papua Province, Indonesia.
The Grasberg mineral district in Papua, Indonesia, is home to one of the world’s largest copper and gold deposits. Currently, we are in the final phase of mining the Grasberg open pit. We are also engaged in multiple projects within the Grasberg mineral district, focusing on the development of several large-scale, long-life, high-grade underground mines. Altogether, these underground mines are expected to produce substantial amounts of copper and gold as we transition from open-pit to underground mining at Grasberg.
Freeport-McMoRan (FCX) is a leading international mining company headquartered in Phoenix, Arizona, USA. FCX operates large, long-lived assets with significant reserves of copper, gold, and molybdenum, spread across various geographic locations. FCX’s asset portfolio includes the Grasberg mineral district in Papua, Indonesia, the southwestern deserts of the United States, and significant mining operations in North and South America, such as the large-scale Morenci mineral district in Arizona and the Cerro Verde operations in Peru. FCX is the world’s largest publicly traded copper producer. Its shares are listed on the New York Stock Exchange under the symbol “FCX.”
MIND ID is Indonesia’s Mining Industry Holding, which includes PT Indonesia Asahan Aluminium (Persero) (Inalum), PT ANTAM Tbk, PT Bukit Asam Tbk, PT Timah Tbk, and PT Freeport Indonesia as its members.
Job Descriptions
Provide geotechnical recommendation and/or services to the PTFI U/G Mines by directing the design, support and monitoring of geotechnical aspects of U/G Mine facilities and operations to ensure safe and efficient operation of U/G Mines.
The key duties and responsibilities of this position are:
- Meet the PTFI Safety and Environmental Programs and standards.
- Inspect and analyze ground condition for any new development heading to ensure the recommended support design fit with the actual ground condition.
- Evaluate and modify ground support design for new development areas using GSST tools to ensure the lifetime stability of the opening.
- Analyze ground movement and damage progress as impact of induce stress or mining activity (blasting, caving, production, etc) to provide appropriate action plans, in order to ensure safety of the miners and also to achieve production target.
- Analyze seismic monitoring data to indicate ground response and seismic related hazards to ensure the safety of underground facilities, access and production areas.
- Inspect and monitor ground condition of DMLZ mine fix facilities (e.g. ore pass, loading point, crusher, vent raise, access, office and any mass excavation) and provide warning of unsafe condition and short/long term mitigation plan.
- Monitor displacement by conducting convergence measurement using geotechnical devices (e.g. tape or scanner) on any drift and working areas, particularly for complex and high-risk areas, to ensure safe and efficient operation of mine. Recommend re-support or rehabilitation as required.
- Conduct cave monitoring program such as TDR and open hole measurement and construction of cave shape by combining all monitoring data (including seismic, cave tracker and smart marker) to interpret cave propagation and material movement.
- Update database system for geotechnical data/information and reports/recommendation so the database is accessible and preservable.
- Prepare daily, weekly and monthly report for reviewing from senior engineers.
- Develop his skills and knowledge to go along with new technology and methods to improve the service to clients and cope with new project and case study in block cave mining.
