Stress Inversion of Coal with a Gas Drilling Borehole and the Law of Crack Propagation

Stress Inversion of Coal with a Gas Drilling Borehole and the Law of Crack Propagation

For studying the law of crack propagation around a gas drilling borehole, an experimental study about coal with a cavity under uniaxial compression was carried out, with the digital speckle correlation method capturing the images of coal failure. A sequence of coal failure images and the full-field...
