Conclusions

  1. 1.

    The fracturing of rocks is a process evolving in time on the basis of a stochastic accumulation and development of cracks.

  2. 2.

    Acoustic emissions allow monitoring the accumulation of the number of cracks and evaluating their sizes.

  3. 3.

    For monitoring the emission of elastic energy, computerized systems are necessary, capable of real-time recording of all acoustic signals above a desired threshold and measuring their amplitude and time parameters.

  4. 4.

    The formation and development of a fracturing source can be detected reliably by variations of the amplitude-time spectra of AE and the variation of the statistical parameters of AE.

  5. 5.

    The similarities of the fracturing processes at different size scales allows using the predictive features detected to forecast rock bursts.
