    Characterization of Acoustic Emission Parameters during Fracture Process of Siltstone with Prefabricated Void by Xiaorong Liu, Lulin Zheng, Hengyi He, Qing Qiu, Ziqi Liu, Xuefeng Li, Lin Yan, Gang Huang

    Published 2022-01-01
    “…The research results show that there are multiple stress drops before the deformation and failure of the rock sample with prefabricated drill holes; there is a positive correlation between the diameter of the drill hole and the power law index of the stress drop distribution; the acoustic emission activity of the rock during the deformation and failure process can be indirectly reflected the evolution of microfractures; the energy probability density function under different borehole diameters conforms to the power law distribution; the critical exponent obtained by the maximum likelihood estimation has an optimal plateau value, which can accurately characterize the power exponent of the energy distribution; the launch waiting time and aftershock sequence have a good power-law distribution in logarithmic coordinates. …”
