In the underground mining process, the evolution of fissures, fractures, and breakages in
overlying rock strata can lead to water inrush and many other serious risks, including rock …

Carbon dioxide (CO 2) injection into deep coal seams holds considerable significance in
both carbon mitigation and enhanced recovery of clean coalbed methane (CBM). The CO 2 …

The composition and micromechanical properties of rock minerals have important effects on
its macroscopic mechanical performance. The composition, proportions, and morphology of …

This work aims to investigate the failure and mechanical behaviors of coal rocks during CO 2-
desorption. The unconfined and confined compression experiments with certain depletion …

Sinkholes are a major geohazard caused by underground mining, significantly deteriorate
the ecological environment. To understand deeply the formation mechanism of widespread …

Accurate determination of the representative elementary volume (REV) size plays a pivotal
role in analysing the mechanical properties and failure processes of heterogeneous rocks in …

The crack initiation stress threshold (σ ci) is an essential parameter in the brittle failure
process of rocks. In this paper, a volumetric strain response method (VSRM) is proposed to …

The complex and special mechanical properties of Xiyu conglomerate are of great
significance to the construction of water conservancy and hydropower engineering. The …

Purpose Accurate presentation of the rock microstructure is critical to the grain-scale
analysis of rock deformation and failure in numerical modelling. 3D granite microstructure …

The internal microstructures of rock materials, including mineral heterogeneity and intrinsic
microdefects, exert a significant influence on their nonlinear mechanical and cracking …
