Model Coal Tunnel Fires in Ventilation Flow
The Bureau of Mines is using model ducts lined with coal to study the nature of coal mine fires, their rate of propagation, their influence on ventilation airflows, and their response to sealing and other fire suppression measures. For scale-modeling purposes these studies are being carried out in various size ducts; eventually they will include a full-size mine entry in the Bruceton multiple-entry Experimental Mine. To date, work has been carried out in an insulated 9.1-m-long duct with a 5-cm thickness of coal leaving a 23- by 23-cm square opening for air ventilation. Fire propagation processes in this duct were mainly transient in nature, owing to the relatively small length-to-diameter ratio. This report describes the experimental equipment employed and the results obtained to date.
