Generally, there is a seismogenic process before rockbursts occurrence, accompanied by
formation of a great amount of micro-cracks and release of micro-seismic energy (micro …

Landslides (LS) represent geomorphological processes that can induce changes over time
in the physical, hydrogeological, and mechanical properties of the involved materials. For …

During the excavation of deep rock engineering projects under high geostress, the brittle
failure of hard rock often occurs. To understand the excavation-induced fracturing process of …

The mechanical behavior of coal is the key factor affecting underground coal mining and
coalbed methane extraction. In this study, triaxial compression and seepage tests were …

Early warning of rockbursts remains a worldwide challenge in rock engineering. In this work,
a microseismicity-based method of rockburst warning in tunnels is proposed to warn of and …

To study the influence of hydraulic slotting inclination on the mechanical behaviors of coal
seam during mining process, uniaxial compression experiments on coal specimens with a …

Microseismic (MS) event locations are vital aspect of MS monitoring technology used to
delineate the damage zone inside the surrounding rock mass. However, complex geological …

In the present study, structural model test using rectangular prismatic granite specimen 200
mm× 200 mm× 200 mm with a horizontal central circular hole of 78 mm diameter was …

Acoustic emission (AE) and microseismic (MS) events are indicators of rock fracturing or
damage as the rock is brought to failure at high stress. By capturing the AE/MS events …

The failure mechanism and failure mode of anisotropic rock masses are very different from
those of isotropic rock masses. For unsupported tunnels, the failure modes of anisotropic …
