Mechanism and Classification of Coal and Gas Outbursts in China
Advances in Civil Engineering, 2021 Coal and gas outburst is a kind of complex dynamic disaster with short duration and strong explosiveness, and the modes and strength of the outburst are determined by the in situ stress, gas pressure, and physical and mechanical properties of the coal ...

Numerical analysis of natural gas pressure during coal and gas outbursts [PDF]
Energy Science & Engineering, 2021 AbstractAny disturbance in the ventilation system of a mine during a coal and gas outburst can lead to secondary disasters. This is because, on the one hand, the expansion power of the outburst source makes the airflow in the ventilation system countercurrent, causing the gas in this system to exceed the allowable limit.

Risk prediction of coal and gas outburst
Gong-kuang zidonghua, 2022 In order to solve the problems of low accuracy and slow response speed of existing support vector machine (SVM)-based coal and gas outburst prediction methods, a risk prediction method of coal and gas outburst based on improved grey wolf optimizer (IGWO) optimized SVM is proposed. The influence degree of each influencing factor on coal and gas outburst
