Toward A Reinstatement Of The Traversing Method For Mine Air Flow Rate Measurements ?

Traverse anemometry is still widely used today. In this paper an investigation of the influence of three factors which are believed to contribute to the resulting error of the method, is reported. They are the shape of the traversing path, the size of the vane anemometers and the air velocity pattern. These factors are experimentally studied on a test facility developed specially for this purpose. Taking into account the results of 576 measurement sessions, as well as published information, some preliminary conclusions are drawn, and additional questions are raised.
