Application of High expansion nitrogen foam to control mine fire – a case study

High expansion nitrogen foam technology has been found an effective technique world over for controlling underground mine fire in this paper the conventional methods adopted in coal mines for dealing a fire have been briefly discussed. Attempts have been made to highlight the advantages and merits of high expansion foam technology over the other techniques. A success story of application of high expansion nitrogen for controlling underground fire in record time in MCL mines has been presented and reference of other places in Indian coal mines where the technique were applied successfully, has been made in brief
