Abstract Appropriate mine ventilation is absolutely critical for safe underground mine work. Ventilation is required in underground mine work to dilute potentially harmful gases and pollutants, maintain thermal comfort, workforce morale and productivity by providing a safe, comfortable underground working environment. Mine ventilation fans provide a flow of fresh air to the underground mine workers by creating an air release system which is able to discharge unwanted contaminated air to the outside environment. So, it is relatively challenging to appropriately control mine ventilation fans in order to maintain Occupational Health and Safety standards for workers. Moreover, advanced ventilation control systems can bring major improvements in high environmental impact mine sites. This project focuses on the study, investigation and development of a new control system for the exhaust mine ventilation fan at the Crocodile Gold mine site which is located 60 Km North of Pine Creek. Employed in the control system are a Programmable Logic Array (PLC) and a Human Machine Interface (HMI) that provides both flexibility of control & ease of operation. Introduced here is a simplified approach to understanding mine ventilation fans, ventilation networks and appropriate Australian Standards. In addition, a simplified approach to model a control system is described with the help of electrical drawings and other inter-related subsystems. The ventilation system of the Cosmo Deep Mine site is briefly analysed and background engineering calculations are provided. In the second development stage multiple fans will ensure the delivery of fresh air. A section of this thesis also deals with the ventilation resistance calculation and the modelling of different networks by the Ventsim Software. The results from this modelling are to analyse and provide feasible methods to calculate appropriate ventilation networks. As per customer requirements, this project is expected to design a control system for the ventilation fan examined and to realise an in-depth study and research that based on the materials and equipment selection, functionality and compatibility of the overall system.
