During the stress-induced rock failure process, anomalies in the Infrared Radiation (IR) can
be observed. To study the response relationships between rock IR temperature and spatial …

Classification of rock micro-fractures by acoustic emission (AE) parameters is of great
significance for rock health monitoring, instability assessment, and precursor warning. But …

Geological sequestration of CO 2 is an effective way to achieve the goal of reducing global
warming and carbon neutralization. The complex CO 2–coal interaction will lead to the …

Fracturing process and possible factors influencing crack initiation, propagation and
coalescence of granitic rocks are investigated using a grain-based finite-discrete element …

The quantitative determination of the geological strength index (GSI) and disturbance factor
(D) in the Hoek–Brown failure criterion is of great value because it can increase 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 …

In recent years, microwave mechanical rock breaking—an energy-saving technology with
environmental benefits and high efficiency—is increasingly being used to improve the rock …

To investigate the acoustic emission characteristic of rock under different compressive
loading rates, a numerical approach using the bonded-particle model (BPM) is adopted in …

To obtain a comprehensive understanding of the difference between deep and shallow
rocks, and the damage evolution laws of a rock mass at different depths, a case study was …

The experimental results show that initial damage has a clear effect on the creep behavior of
rock. However, among the current creep models for rock, few consider the effect of the initial …
