To explore the mechanical responses and failure patterns of coal samples subjected to
various gas pressures and cyclic dynamic loads, a split Hopkinson pressure bar (SHPB) test …

In this study, a series of uniaxial compression and acoustic emission (AE) tests were
conducted on sandstone specimens immersed in water for different durations (0–720 h). The …

Rockburst disasters occur frequently during deep underground excavation, yet traditional
concepts and methods can hardly meet the requirements for support under high geo-stress …

Rock serves as a crucial source of building materials. Understanding the dynamic strength
of rock under varying prestressed conditions is essential for evaluating structural stability …

Coal and gas outbursts are a major dynamic hazard in underground coal mining, and
predicting these events is challenging due to their complex mechanisms. This study …

The fracture failure of flawed coal has always been a problem in underground engineering.
Therefore, it is necessary to monitor crack propagation and damage evolution during coal …

Full understanding of dynamic mechanical characteristics of coal samples under true triaxial
condition is of great significance for preventing and controlling deep coal and rock dynamic …

Abstract The three-dimensional (3D) stress waves of coal samples were studied using a true
triaxial split Hopkinson pressure bar compression rod. The results indicate that the 3D strain …

The fracture behavior and various of mechanical mechanisms of shale are greatly
influenced by the bedding surface. To study the effects of bedding angles on the crack …

Previous studies focused mainly on temporal-spatial analyses of thermal infrared radiant
temperature variations based on statistical parameters for rocks. These spectral analyses …
