Airflow and Cooling Demand Estimating - Multiple Projects
Development of estimates for total and local airflow requirements, heating, bulk and spot cooling. Approaches have included activity-based estimating methods supplemented by VentSim modelling, stand-along tools for options evaluation, integrated estimating within scheduling software (Deswik) for resource leveling.
Decline Ventilation - Australia
Modelling, equipment selection for two single heading declines reaching ultimate lengths of >2 km using forcing ventilation and layflat ventilation ducting.
Crusher and Ore Handling Dust Management - Multiple Projects
Mine and mechanical design changes to enable effective dust extraction from materials handling systems including ore bins, apron feeders, conveyors, and crushers. Support to mechanical engineering studies for integration of dust extraction systems into mine design, ventilation, mine services, and waste stream handling.
Ventilation on Demand (VoD) Opportunity Assessment - Australia
Assessment at an existing large mining operation. Multiple options for level of control, granularity of control (primary fans, secondary fans, regulators), and frequency of changes to system were reviewed considering operational requirements. Found that best value was to use existing primary fan variable speed control on quarterly basis.
Ventilation on Demand (VoD) System Design - Asia-Pacific
Specification, design, and control philosophy for a large VoD system (+300 controls, +100 instruments). Design and system logic handed over to client and systems integrator for execution.
Airway Profile Optimisation - Multiple Projects
Financial optimisation of primary ventilation airway dimensions. Complex cases included integration with other disciplines (power systems, geotechnical, fan mechanical) where 'optimal' performance conflicted with what was practically achievable. Solutions to meet client constraints include high speed airways, large vertical fans, and multi-pass benching.
Owner's Team Engineer - Multiple Projects
Owners team ventilation engineer for multiple projects including surface and underground primary fan procurement, mine cooling systems, ventilation controls / infrastructure, dust scrubbing systems. Drafting and review of technical specifications, procurement strategy, value engineering.
