Abstract

Coal mine fire not only cause huge national economic loss but also creates serious environmental hazard leads to global warming and has a large potential for causing loss of life to the workers involved in mining operations. A huge amount of the prime coking coal reserves of India is locked in the Indian coalfields and it cannot be extracted without extinguishing the existing coal fires. Gradually these fires are spreading perpetually in more areas. Many approaches have been attempted in this direction so that hazard to men and environment as well as economic losses can be minimized. Use of chemical additives to retard spontaneous heating is an important method which can be adopted to prevent or delay the occurrence of spontaneous combustion. In this situation it may sometimes be necessary to use chemical additives for reducing the intensity of fire so that the coal production will not hamper. This paper presents the results of a set of experiments involved the analysis with certain chemicals, individually & in combination in mechanistic prospective and finally best combination was selected.
