Coal deformation energy and gas expansion energy are the main power sources for coal
and gas outbursts (called outbursts for short). Although the combined effect hypothesis of the …

Shale microstructures control the capacity of the formation to store hydrocarbons and its fluid
flow. However, microstructural complexity and multiscale heterogeneity is a challenge in a …

Ultrasonic physical stimulation is a promising approach of coalbed methane enhancement
recovery. This study is devoted to quantitatively characterizing the damage of multi-scale …

The permeability rebound and recovery are the key factors affecting the production efficiency
of CBM and the storage capacity of CO 2 during the CO 2-ECBM process. In this study, fully …

To explore the evolution features of the pore–fracture structures and permeability behaviors
of coal under high temperatures and nitrogen atmospheres, an infrared rapid heating …

Water-locking flocs formed by ultrafine tailings particles will damage the thickener underflow
concentration in the thickening process during paste preparation. The relationship between …

Foam concrete encounters a fundamental challenge in balancing lightweight and high
strength. Pore optimization is the key to address this problem. This study starts with rheology …

Characterization of microscopic structure and macroscopic physical property are the basis
for better understanding of coalbed methane reservoirs. X-ray computed tomography (CT) …

To study the evolution characteristics of the pore-fracture structures and seepage properties
of coal in the process of spontaneous combustion, a high-temperature tube furnace was …

The low porosity and permeability characteristics of coal seams have become the main
bottleneck restricting high-efficiency extraction of coalbed methane. At present, enhanced …
