AIR FLOW MODELING IN DEEP WELLS: APPLICATION TO MINING VENTILATION

In this paper, we present a novel air flow modeling strat-egy for deep wells that is suitable for real-time control of large-scale systems. We consider the mining venti-lation control application, where specifically designed models are crucial for new automation strategies based on global system control and energy consumption op-timization. Two different levels of complexity are pro-posed. Starting from a general model based on Navier-Stokes equations, we derive a 0-D, Bond Graph model. This model is used to set a real-time simulator for the mine aerology problem. 1
