To study the effect of ultraviolet light on spontaneous combustion characteristics coal, Lijiahao long-flame coal was selected for irradiation treatment with a self-made device. After 0, 1, 2, 4, and 8 h, thermogravimetric experiments Fourier transform infrared spectroscopy were carried out. Compared raw dry cracking temperature, ignition point maximum weight loss rate temperature samples irrad...
