Abstract—In order to reduce the pollution and toxicity of current method for fire suppressing, and it is more applicable in low
coal fire fighting materials used in underground mines, this gas mines; 2) Injecting nitrogen, an expensive fire prevention
paper proposes that the functional ionic liquid, a kind of green measure, is affected by nitrogen purification, temperature and
material, may be utilized to suppress the spontaneous fire based stability of equipment. It depends on the reliability of nitrogen
on coal’s chemistry structures. According to the Fourier injecting techniques; 3) Injecting gel is usually more efficient
Transform Infrared (FTIR) spectroscopy experiment in low- in local parts or some places without specific fire sources, but it
temperature oxidation of coal, we found that the aliphatics active is not helpful when the fire area is expanded; 4) Sand-
groups, decreasing with rising temperatures, react with oxygen suspended grout is a creative and efficient fire-fighting material
