Pathway mapping is a new tool in the 3D-CANVENT ventilation software to track potential air pathways in complex mine ventilation systems and help in determining the pressure differences to deliver the required airflow to underground workplaces. After a ventilation model is established, a structure tree of the ventilation system can be formed from the branch series based on the ventilation parameters, locations of fans and regulators, and the airflow state as obtained from mine ventilation simulation. In order to find the unique pathway to each workplace, strict rules must be set to respect the structure tree and the priority of different fans in operation. The pathway tracking system provides a graphic interface with multi-functional tools and data sheets for generating and manipulating the structure tree and tracking the airflow pathways to different locations in the mine. It can be used in designing and managing the advanced mine ventilation systems, such as the ventilation on demand (VOD) systems, and to efficiently deliver the fresh air to the production areas in deep mines.
