Abstract

In 1981, CMRI, after due investigation at Jhingurda opencast (OC) bench fire, concluded that the OC bench fire is due to the fractures created at the coal massive by blasting and by the movement of heavy vehicles. These fractured zones are vulnerable for rapid coal-oxygen interaction and heat build up leading to spontaneous heating. CMRI further concluded that for a successful combating of these fires, the heat stored in the concerned fractured zones has to be extracted by proper use of water and then chances of reignition in the area should be avoided by covering the area with a suitable protective coating. CMRI standardised the method of cooling and developed a bitumen based protective emulsion in collaboration with STP, Calcutta. In this article the author suggests a slight modification in the methodology whereby sufficient quantity of coal can be obtained during combating operation, bringing down the cost of fire fighting operation practically to nil and conserving the coal in a better way.
