Technical Expert, Geotechnical Engineer - Monitoring

Requisition ID: 147948

Location:

Papua, ID, 99967

Category: Engineering Services

The Underground Geotechnical Group has a major role in the success of PTFI as it continues to operate the mines and bring new mines in development and production; ensuring that the underground operations are geotechnically reliable; the global and local support systems provide a safe working environment; and, that the mines are monitored and managed to provide the expected revenue stream. The work carried out by the group includes rock mass characterization, support design, ground control, hydrology, QA/QC of support systems, monitoring of ground and cave behavior and evaluation/prediction of cave performance.

*Additional Responsibilities:*

• The Technical Expert Underground Geotechnical Engineering role exists to provide operational geotechnical support to PTFI’s mines. The intent of the role is provide:

• Core underground geotechnical design expertise across operating and developing mines, including KL’s transition from development to production.

• Ground support design and ground control skills in an operational environment

• Assistance with the evaluation of cave performance and production forecasts as well design and commissioning of the monitoring system and related interpretation to support business strategic objectives

• Assist in the development of the Underground Geotechnical group that provides key technical advice and support to the Grasberg Underground Operations.
• Geotechnical analysis and design for the GBC, DMLZ and Kucing Liar (KL) caving operations and for the Big Gossan stoping operation, all within PTFI’s Grasberg business unit.
• Assist in the development of partnering arrangements with key specialist providers, such as rock bolt suppliers and equipment OEMS.
• Provide expert advice to ensure that best geotechnical design and ground control practices are applied to the underground mines.
• Provide expert advice to ensure that appropriate geotechnical decisions are undertaken. These will range from advice on ground support in very soft ground, to guidance on mine seismicity to cave performance.
• Develop, coach and mentor national staff to build capacity, ensure knowledge transfer and that analyses follow international best practices.
• Provide professional advice/recommendations to PTFI leadership and supervisory staff.

Qualifications

• Bachelor’s degree in Mining Engineering, Civil Engineering of Geological Engineering or acceptable Tertiary qualifications with at least ten (10) years of working experience in the application of geotechnical engineering to underground mining.
• Demonstrated expertise in geotechnical engineering and ground control as applied to underground mining.
• Demonstrated ability to work with others and communicate complex issues.
• Highly focused on geotechnical analysis and design as applied to underground mining and assessing geotechnical aspects of underground mine production. This requires in depth…
