Predicting Rock Bursts in Rock Mass Blocks Using Acoustic Emission
Resources, 2022 Geophysical methods for local rock burst prediction are currently being developed along two lines: improving recording equipment and improving data processing methods. Progress in developing processing methods is constrained by the lack of informative prognostic models that describe the condition of rock mass, the process of rock mass fracturing, and ...
