The characteristics of mine airstreams, such as their magnitude in the time and frequency domain and their spatial distribution, as defined by isovels, must be considered when making a measurement. The possibility for erroneous measurements is greatly increased when fixed-point sensors for mine monitoring systems are used. However, an a priori understanding of the airstream characteristics can be used to reduce the possibility of erroneous readings. This paper describes the problem, presents data to illustrate the nature of the problem, and provides recommendations for alleviating the problem.
