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 …

As key flow properties for coalbed methane production, greenhouse gas reduction through
CO 2 storage in coal and gas drainage to improve mining safety, knowledge of gas diffusion …

We report laboratory experiments to investigate the dynamic failure characteristics of
outburst‐prone coal using a split Hopkinson pressure bar (SHPB). For comparison, two …

With the development of computer science, many machine learning algorithms such as the
back propagation (BP) neural network algorithm have been applied to the prediction of coal …

As the one of the most catastrophic hazards in underground mining, coal and gas outburst
seriously threatens the safe mining of collieries. To understand the formation and transport …

This research reviewed the mechanics and gas desorption properties of intact coal, and
tested the crushing work ratios of different intact coals, and then, studied the stress …

The study of coal and gas outburst mechanisms is necessary for the safety and efficiency in
mining. Gas expansion energy is a major factor in outburst initiation. However, the amount of …

Coal and gas outburst is the most serious dynamic disasters in coal mining. The essence of
mechanics is the instability and destruction process of coal and rock caused by energy …

Coal and gas outbursts are common mining hazards encountered worldwide. As we mine
deeper, the complexity of these outbursts demands smarter, more precise risk identification …

With the increase of coal extracting depth, a considerable number of dynamic disasters
display the co-occurrence and coupling effect of rockburst and coal–gas outburst, which is …
