    The structural parameters evolution of coal due to the influence of intrusions of hot magma was investigated and analyzed. X-ray diffraction and laser confocal microscope Raman spectroscopy were used to test and analyze 4 coal samples undergoing varying contact-metamorphism by igneous magmas in borehole No.13-4 of Zhuji coal mine, Huainan coalfield. The result showed that coal XRD spectrum showed higher background intensity, with the 26° and 42° nearby apparent graphite diffraction peak. Two significant vibration peaks of coal Raman spectra were observed in the 1 000~2 000 cm-1 frequency range: broad “D” peak at 1 328~1 369 cm-1 and sharp “G” peak at 1 564~1 599 cm-1. With the influence of magma intrusion, the relationship between coal structural parameters and coal ranks was excellent.
