Geotech Engineer & Pit Control

  • Pertambangan – Eksplorasi & Geosains
  • Musi Rawas Sumatera Selatan
  • 10-Dec-2024
  • Kontrak

Requirements

  • Minimal having bachelor degree in Civil Engineering, Mining Engineering, Geological Engineering. 
  • Having relevant work experience in geotechnical mining industry as least 3 years.
  • Preferably able to operate engineering and geotechnical software (Slide 2D, RS2D, RS3D, Autocad, Minescape, etc).
  • Preferably able to operating the Instrument Monitoring Geotech (SSR, Robotic, Extenso, Prism, VWP, Inclino, Crackgauge).
  • Analytical, problem solving skills together with mechanical aptitude to solve technical difficulties (troubleshooting, geomechanic laboratory test).

 

Responsibilities

  • Develop, update, and apply the geotechnical system management.
  • Plan and collect geotechnical data, including drill core analysis, SPT, CPT, and laboratory analysis methods.
  • Conduct geotechnical scanline mapping to determine and measure the strike/dip of joints, faults, folds, and cracks.
  • Analyze slope stability for all pit designs and disposal sites using geotechnical software for slope stability (e.g., Slope/W, Slide, Plaxis).
  • Monitor slope stability of pits and disposal sites using prism monitoring, extensometers, and visual observations.
  • Perform back analysis of failure conditions and provide reanalysis of slope stability for open pits, diversions, and disposal site designs (e.g., pit dump and outpit dump).
  • Prepare weekly and monthly reports on observed geotechnical hazards and critical areas (e.g., hazard mapping and identifying potential failure areas).
  • Conduct risk assessments for geotechnical hazards and develop mitigation or evacuation plans in case of failures.
  • Supervise geotechnical drilling activities, including collecting full-core samples, SPT, and CPT.
  • Control pit geometry by ensuring proper undercut, overcut, slope height, berm width, and monitoring areas with potential saturation issues (e.g., water ponding and groundwater presence).
