Coalbed methane (CBM) is a form of natural gas that is extracted from coalbeds.
Characterization of CBMs is very challenging mostly due to the very complex fracture system …

With the development of deep, underground coal mines in China, the failure mechanism of
the rocks surrounding roadways is becoming increasingly complicated and the …

This paper presents the longwall face stability analysis under a realistic representation of
geological structures and caving behaviours within coal seam. Face spall and its …

The efficiency of a coal bed as a reservoir of methane and CO 2 sink primarily depends on
its fracture permeability. Conventional techniques of permeability estimation from drilled …

The bursting liability is very important to evaluate the risk of rock burst in coal mine.
Conducting uniaxial compression test is the main method to study the bursting liability of …

Coal rock is a type of geological material containing a natural cleat system. During coalbed
methane extraction, the influence of this system on the damage behavior and failure …

This paper analyzes and compares the deformation, failure characteristics, and energy
characteristics of coal and rock under uniaxial compression. It is considered that the change …

Abstract Knowledge of the mechanical properties of coal seams is important for the coalbed
methane extraction. Cleats are widely existing in coal reservoirs and play a significant role in …

After rock burst and spontaneous combustion, a coal seam is exposed, and this form of
compound disaster shows new characteristics. Therefore, basic research on oxidized coal is …

To investigate the periodic disturbance and damage characteristics of coal under different
impact pressures, the stress‒strain failure and damage trends of weak, impact‐prone coal …
