Cannington Mine has installed nine remotely controlled regulators in its underground operation. The expansion of the mining operation caused a need for the improvement of the quality of its ventilation. It was found that an economically viable key to improve the ventilation system was to advance regulator technology. The remotely controlled regulators are replacing the original manually positioned intensive drop board type. They are controlled and monitored from the surface control room by the mine’s process control system, Citect.Although engineers involved in ventilation at Cannington Mine have indicated that the remote regulators have improved the mine’s ventilation, it is apparent that the use of the remote regulators is far from reaching its maximum potential. Thus there has been a need for investigation and analysis into methods of maximising the benefit of the remote regulators. The study investigates and analyses Cannington’s ventilation system in relation to the use of remote regulators with the aim of maximising the benefit of the regulators.Maximizing the benefit of the remote regulators involved analyzing the ventilation system to find the best possible ways in which to deliver the available airflow to the working levels in the required quantities as it is needed. Throughout the duration of a shift, the airflow on a working level needs to be adequate to clear blast fumes at the start of the shift so that re-entry times are minimized and that blast fumes are cleared directly out the return airway system (so that the airflow through other levels and the decline is not contaminated) and provide adequate ventilation throughout the shift so that diesel fumes and heat is adequately ventilated (to Cannington’s ventilation standards) to ensure the well being of the workers. The study addressed researching related topics, investigated the ventilation system, and developed procedures and recommendations....
