Effects of coal's initial macro-cracks on rockburst tendency of rock–coal composite samples [PDF]
Royal Society Open Science, 2019 In the present study, uniaxial compression tests were conducted on sandstone–coal composite samples to investigate the effects of original macro-cracks in coal on the rockburst tendency. First, the energy dissipation theory was used to derive the elastic
