Experimental and numerical simulation study on the dynamic fracture of coal by gas expansion

Abstract The high‐pressure gas expansion‐induced deformation and dynamic fracture of coal are important parts of coal and gas outburst. To better understand the law of this process, laboratory experiments and numerical simulation are used to study the law of damage. A cavity with different pressures...
