Coal and gas outburst is a frequent dynamic disaster during underground coal mining
activities. After about 150 years of exploration, the mechanisms of outbursts remain unclear …

Coal fines can substantially influence coal seam gas reservoir permeability, thus impeding
the flow of gas in coal microstructure. The coal fines generation and migration are influenced …

When coal under creep deterioration is disturbed by impact load, it is easy to induce
catastrophic instability disasters, rock burst. To analysis the fracture and failure evolution of …

Precursor information of rock fracture is a prerequisite for rock dynamic disaster (RDD)
prediction. To investigate the precursor information of rock fracture based on pressure …

The evolution of coal permeability is very complex under the influence of coupled multiple
processes. This is the primary motivation why numerous coal permeability models have …

A triaxial creep model for deep coal considering temperature effect based on fractional
derivative is proposed for the condition of triaxial stress state. In order to study the …

In many major rock projects, services have spanned decades or even hundreds of years. For
engineering design, it is necessary not only to ensure the safety of personnel during …

In coal mining industry, with the depth growing of coal mines, the creep behaviours of coal
and rock can extensively affect the mining safety, coalbed methane recovery and geo …

Methane adsorption/desorption not only causes coal matrix shrinkage and swelling, but also
has an important influence on the microcrystalline structure of coal. In this study, high …

Coal seams are usually fractured reservoirs where the factures/cleats are fluids flow
channels, and the matrix blocks serve as the storage space. The gas transport within the …
