Summary

Under moderate supervision, provide mining and mill (plant) operations with engineering support related to design, construct, and operation of tailings storage facilities (TSF’s), heap leach facilities (HLF’s), storm water dams (SWD’s), or other site water retention structures. Serve as a resource for geotechnical information and analysis.

Essential Functions

Operational Support
  • Work with tailings and dam operations on a regular basis to ensure successful implementation of the operations and maintenance (O&M) manuals and tailings deposition plans.
  • Consult with tailings supervisors and operators regarding day-to-day concerns and opportunities.
  • Assist operations in maintaining minimum freeboard, maximum beach development, and good pond management.These items should be developed as a priority if clear operational rules are not written and assigned to specific persons.
  • Develop and maintain databases for slurry characteristics including tailings gradation, slurry density, and mill tonnage. Perform statistical analysis to understand typical slurry behavior and identify erratic behavior, correlating it to upset conditions. Apply information to design and operation of the tailings management systems.
  • Assist with pool bathymetric surveys and review of satellite and ground survey data and use results to understand tailings depositional behavior, evaluate beach slopes, confirm raise rates, estimate remaining capacity, and calculate dry density of in-place tailings.
  • Work closely with mill operations and metallurgy to understand and convey how any potential process changes could affect the tailings delivery systems and deposition.
  • During upset conditions, provide engineering support to tailings operations personnel for safely and effectively mitigating issues.
  • Hold regular (weekly, monthly) tailings meetings with engineering, management, tailings operations, environmental and other mine/mill personnel to manage deposition and TSF infrastructure.
  • In collaboration with operations personnel, assist in writing and reviewing standard operating procedures (SOP’s).
  • Arrange for operator training in collaboration with the operations supervisor/superintendent.
Engineering
  •  Assist in coordinating corporate third-party review team visits, including preparing and delivering the kick-off presentation, participating in inspections, and implementing resulting recommendations and best practices. Provide quarterly update to corporate and senior management including progress of each recommendation and estimated completion date.
  • Communicate with and engage the Engineer of Record (EoR) regarding tailings and water storage dam operations, performance, observations, concerns, data, etc.
  • Work with consultants on planning of studies, such as field investigations or material characterization programs; develop methodology for analysis and interpret results.
  • With the assistance of CMOC International’s corporate team, perform technical review on all geotechnical related work on TSF’s, HLF’s, and water retention dams by consultants or others.
  • Assist EoR in developing O&M manuals and emergency action plans (EAP’s) for TSF’s and water retention dams; update annually, including tracking and distributing to stakeholders.
  • Prepare short- and long-term forecasts and OPEX/CAPEX budgets for tailings and related water management work; provide updates to site management and accounting as required.
  • In collaboration with all stakeholders, identify closure requirements and implement closure strategies during operations, as required.
  • Actively engage in major projects managed by the corporate technical team. Support can include preparation of information, design reviews, construction review/oversight, and construction field recommendations.
  • In collaboration with tailings supervision or other stakeholders, evaluate new products related to operation or environmental controls of TSF’s. Coordinate various trials for the evaluation of potential new products such as dust control additives or tailings delivery infrastructure such as valves, piping, etc.Evaluate cost benefit and other advantages of potential items
Monitoring
  • Coordinate and participate in inspections including those by:
    • Corporate geotechnical and water management team
    • Technical Review Board
    • Engineer of Record (EoR)

    • Piezometers and wells
    • Survey monuments
    • Horizontal drain flows
    • Weir flows
    • Tailings line flows and pressures
    • Bathymetric survey
    • Satellite survey

  • Assist with periodic bathymetric and beach/embankment crest surveys, and analyze results for tailings deposition modeling calibration, as well as tailings and reclaim system water balance.
  • Participate on TFM’s water team regarding site-wide water balance modeling and defining historic, current, and forecasted TSF, HLF, SWD and other dam’s water management and consumptive uses.Assist the water team with short-, medium-, and long-term forecasting.
  • Incorporate and coordinate water management objectives with tailings deposition and dam safety objectives.
  • Monitor and inspect water conveyance and downstream collection ponds/systems.
  • Define water operating rules necessary for safe dam operation focusing on necessary capacity to contain/manage extreme event(s), seasonal, and long-term potential precipitation trends.
  • Review O&M plans for extreme event responses such as pump capacities and back-up electrical and pumping systems.
