Biography

Wendy is a gas handling and ventilation specialist with over 10 years’ experience in industrial gas handling and underground mine ventilation. Her extensive experience with designing and leading gas handling projects ranges from desktop greenfield and debottlenecking studies through to commissioning and operational support. Wendy’s expertise includes development and management of key process and ventilation engineering deliverables such as process/ventilation design criteria, mass and energy balances, ventilation network modelling equipment sizing calculations, and order-of-magnitude capital and operating costs, as well as air emissions inventories and environmental design criteria specific to air point source and ground-level concentrations. Graduating from the University of Adelaide (BEng, Chemical and BSc, Mathematics), Wendy now works from Hatch’s Brisbane office.

Abstract

Diesel to electric—creating a positive paradigm in underground ventilation and cooling

Mining deep orebodies is increasingly becoming the norm as the ‘easy’ orebodies are depleted. Deep ore mining requires significant ventilation and cooling infrastructure to not only meet regulatory requirements for air quality but also to achieve acceptable workplace temperatures with the higher strata rock temperatures and increased auto-compression. At the same time, advances in battery equipment technology are turning the possibility of a battery powered fleet into reality. The switch from a diesel fleet to a battery-powered fleet offers several positive opportunities for the design and operation of a deep mine.
