Research of fracturing mechanism of coal subjected to liquid nitrogen cooling
In order to research fracturing mechanism of coal subjected to liquid nitrogen cooling, submersion tests of liquid nitrogen for natural coal samples are carried out. A laser microscope is employed to observe the extension of native crack and propagation of cracks of coal samples after thermal shock....
