The evaluation of rockburst is becoming increasingly important as mining activities reach
greater depths below the ground surface. In the literature, rockburst assessment has been …

A review of the tensile strength of rock was conducted to determine the relationship between
direct tensile strength (DTS) and Brazilian tensile strength (BTS) and to examine the validity …

Spalling and rockburst are two common failure modes in deep hard-rock tunnels and they
exhibit a strong correlation. In this paper, the process of rockburst induced by spalling is …

Determination of the cracking levels during the crack propagation is one of the key
challenges in the field of fracture mechanics of rocks. Acoustic emission (AE) is a technique …

Considering the linear energy dissipation law under uniaxial compression, a damage
characterization of rocks including the compression energy dissipation coefficient is …

The occurrence of rockburst is closely related to initial high stress state and excavation
unloading effects. To investigate the effects of three-dimensional (3D) stress state and …

A grain-based distinct element model featuring three-dimensional (3D) Voronoi tessellations
(random poly-crystals) is proposed for simulation of crack damage development in brittle …

A considerable number of deep engineering cases show that strain rockbursts occur on both
sidewalls of circular caverns and ultimately form a symmetrical V-shaped notch. To …

Laboratory testing of rocks is traditionally carried out to determine the peak strength using
the ISRM Suggested Methods or other suitable standards. However, it is well known that in …
