Rock engineering is highly susceptible to cyclic loads resulting from earthquakes, quarrying
or rockbursts. Acquiring the fatigue properties and failure mechanism of rocks is pivotal for …

Rock pillars in rock engineering are affected by the stress concentration, which is uneven
and can lead to potential instability after loading disturbance. In this paper, considering the …

As coal mining is extended from shallow to deep areas along the western coalfield, it is of
great significance to study weakly cemented sandstone at different depths for underground …

The occurrence of preset flaws can influence the mechanical, physical and other related
properties of rock samples. To study the failure characteristics of rock samples with 2D&3D …

A series of laboratory-based uniaxial compression tests combined with acoustic emission
(AE) monitoring was conducted to investigate the loading rate dependence of AE …

Temperature can affect the physical and mechanical properties of rocks. With the aim of
better understanding the effect of thermally-induced cracks on rock failure process, we …

Anisotropy caused by bedding structures has a great effect on tensile properties and fracture
behaviours of coal. Acoustic emission (AE) monitoring is a powerful tool in understanding …

Coal burst is essentially a destructive manifestation of stratigraphic structure. Although the
failure mechanism of the structure has been extensively studied using experimental and …

To reveal the instability and failure mechanism of pillars with impact tendency, the Brazilian
test, uniaxial compressive test, cyclic loading and unloading (CLU) tests were performed on …

Open flaws without any filling material are common fracture structures in real rock. To study
the failure characteristics of this fracture structure, small-scale rock-like samples with single …
