1) The document discusses a group project on developing a nitrogen gas injection system to fight mine fires. The group members are Abhishek Kumar, Manish Raj, and Vihang Bhalla, under the guidance of Dr. Santanu Bhowmik. 2) The objectives are to study the different sources of heat in underground coal mines, how different forms of nitrogen gas can be used to control fires, methods of using such gases, and how gas generators can be readily available. 3) It is proposed that installing nitrogen generators at mine sites prone to fires could effectively control fires in a timely manner through continuous nitrogen injection. The generators should be portable, capable of augmentation, and suitable for harsh
