Bituminous coal is rich carbon materials consisted of lots of big hydrocarbon molecules, but its microstructure isn't still clear. Fullerenes were reported in carbon sediments (coal) from the Permian-Triassic (P-T) boundary in Yunan, China [1,2], Inuyama, Japan [3] and the Cretaceous-Tertiary (K-T) boundary in Turkmenistan, Kazakhstan, Georgia, Austria and Denmark [4,5]. However, fullerenes always were suspected in its existence in nature due to lower concentrations. Explosion is a normal way to exploit coal in coal mine, but also a kind of high energized events accompanied with big amount of energy (3000-5000 K, 1010 Pa) in short time [6]. Explosive shock could affect the microstructure and feature of coal, but nothing we knew. Bituminous coal from Fuxin, Liaoning in China was impacted by AN-TNT (Ammonium tri-nitro-toluene), its , microstructure and feature before and after explosion were investigated with X-ray Diffraction (XRD), high-resolution transmission electron microscopy (HRTEM) and Raman microprobe spectrometry in the present paper. After purified by HC1+HF, coal was extracted by toluene (CH4) solvent and characterized through high-pressure liquid chromatography (HPLC) and matrix-assisted laser desorption/Ionization time-of-flight (MALDI-TOF) methods. Mechanism of Fullerene formation was discussed.
