Detailed ongoing simulation and monitoring of the ventilation systems, including TBM power consumption, enabled the equipment to be sized optimally. This also allowed cost effective phase-in of requirements while confidently ensuring healthy and safe working conditions. Although original expectations included large refrigeration plant, the final system consisted of a modest water chiller located at the portal without any air cooling heat exchangers or refrigeration machines in the tunnel or on the TBM train. Detailed screening surveys and hazard assessments to determine radiation doses to the workforce and preparation of formal procedures for compliance with statutory requirements. Training workshops in radiation awareness, procedures and instrumentation were also given.
Emphasis is on user-friendliness of input and practicality of detail of output.
See Link to new VUMA software below. Design of ventilation and cooling systems for a number of rapidly advancing mechanical miner sections in high geothermal rock temperatures. The focus was on a unique problem of heat and dust in hot, dry operating conditions. The project included evaluation and measurement of machine heat loads, network modeling, refrigeration system design, system pre-engineering definition and cost estimates. Detailed design of mine ventilation and cooling systems for multiple reef decline mining operations.
