According to modern coal chemical structure theory, the active chemical structure categories in coal spontaneous combustion process were summed up, which show that the coal spontaneous combustion characteristic structures are dynamic, such as methyl, methylene, hydroxyl, carbonyl and others in coal bridge bonds and side chains. The amount and activity of these structures play an important role in...
In order to reduce the pollution and toxicity of current coal fire fighting materials used in underground mines, this paper proposes that the functional ionic liquid, a kind of green material, may be utilized to suppress the spontaneous fire based on coal's chemistry structures. According to the Fourier Transform Infrared (FTIR) spectroscopy experiment in low-temperature oxidation of coal, we found...
