Rockburst mechanism in soft coal seam within deep coal mines
International Journal of Mining Science and Technology, 2017 A number of rockburst accidents occurring in soft coal seams have shown that the rockburst mechanism involved in soft coal seams is significantly different from that involved in hard coal seams.

Study on the Failure Mechanism of Strain Rockburst
Shock and Vibration, 2022 Among the factors affecting rock mass failure, the stress state has the greatest influence on the mechanical behavior of rock. The mechanical behavior of rock depends on the change of stress path, and the stress of rock mass is closely related to deformation and failure.

Mesomechanism of Effects of Water on Strain Rockburst Prevention
Advances in Civil Engineering, 2021 In deep mining engineering, rockburst is an instantaneous release of a large amount of strain energy stored in rock mass, in which occurrence is closely related to initial high stress state and excavation unloading effect.

Rockburst Inducement Mechanism and Its Prediction Based on Microseismic Monitoring [PDF]
Geofluids, 2021 The rockburst disaster in the hard rock caused by excavation and unloading of deep underground caverns threatens the safety of engineering construction. In recent years, the microseismic monitoring technology, which can dynamically monitor the whole process of progressive failure of rock mass in real time, has been widely used in rockburst monitoring ...
