Practical Application Of Aerostatistics To Multiple Fan System Analysis In Mine Ventilation

Many aerodynamic and thermodynamic properties (such as temperature, pressure, velocity and density) vary widely, and in random spatial and temporal manner for a given underground mine environment. Such variabilities are seldom evaluated statistically, even though the relevant theories and principles are both available and feasible. The main purpose of this paper is to introduce the methodology for applying aerostatistics to the analysis of multiple fan systems in mine aerology/ventilation. Pertinent data were obtained from a small multi-level European coal mine. Results confirmed that aerostatistical methodologies are computationally more efficient. Being grounded in solid engineering statistical theories, they can be used to analyze networked parameters in mine environmental engineering.
