G. Kay and M. Salu, Evaluation of structural component design in life-of-mine planning, 13th Coal Operators' Conference, University of Wollongong, The Australasian Institute of Mining and Metallurgy & Mine Managers Association of Australia, 2013, 387-391.


Industry practice around structural component design has progressed significantly in recent years with a key result being the application of known engineering principles to the design of ventilation control devices and bulkheads. The properties of shot blast products are now well understood with computer modelling and full-scale live blast test analysis having aided the selection of the most effective type of device for specific site conditions. However, as underground mines increasingly focus on life-of-mine planning, understanding the long-term behaviour of installations plays an increasingly important role in structural system design. As many structural components found in underground mines have been designed and certified at time of installation, the review of these installations, specifically the impact of environmental and other factors, provides the opportunity for continued learning and development in this area. Studies conducted at underground mines where structural components have undergone long term testing and monitoring are discussed. The impact of key environmental conditions on the behaviour of structural components in underground mines is described. The limitations of current testing and monitoring processes as well as opportunities for long term mine planning are assessed.
