Survey execution to build a ventilation model, Australian style

摘要

In an age of risk based logic, to ensure the safety of our people in all but the most benign of mine sites we simply cannot justify the absence of a well maintained model of their ventilation circuits. Most Australian mines, at least in the underground coal sector, maintain a validated model to assist with the change management process of minor to major ventilation circuit adjustments. They also routinely utilize validated ventilation models to track ventilation system performance and thus effectively plan and budget for major ventilation infrastructure, as the mine expands. The modeling program of choice in Australia is "Ventsim" software which is now available in a fully graphical 3D configuration as well as the widely utilized 2D version, the models of which are operable on the newer format.
