Description

Although forced auxiliary ventilation is widely employed at heading faces, it is not easy to design an optimum ventilation system for a working face because of the complexity of airflows. Therefore, it is essential to obtain airflow patterns at the face where a heavy machine works.<BR>From this point of view the influence of a machine such as a road header upon airflow patterns are investigated by both methods of measuring of airflow velocity in reduced scale model and using Computational Fluid Dynamics (CFD).<BR>As a result, some important information is obtained concerning the influence of a machine upon airflow patterns in the face. A vortex is generated in the space between a face and a machine, and the wake was created behind a machine. The authors pointed out a possibility that these flows may lead the stagnation of both dust and gases.<BR>The results also show that the CFD is an effective tool for simulating the airflow under varied conditions of the ventilation system.
