Gas outburst is a serious disaster in deep mining. In this paper, we first study the effect of water content on gas outburst, and found that increasing the water content of coal can significantly reduce the elastic modulus and uniaxial compressive ...

Possible mechanism of brightness outbursts of comets
Kinematics and Physics of Celestial Bodies, 2010The mechanism of brightness outbursts of comets based on selective absorption of solar ultraviolet radiation by hydrogen atoms in the cometary head is considered. Due to this process, influence of the radiation on parent and daughter molecules in the near-nucleus region of the cometary head is different.

A mechanism of outbursts of coal and gas
Mining Science and Technology, 1984Abstract Rock and gas pressures combine to cause outbursts of coal and gas. The actions and interactions of geological factors, mining factors and intermediary events during the phenomenon are described.

Application of Coal Mechanics in Coal and Gas Outbursts
2021Coal and gas outbursts are geological failures that occur in underground drainage or mining, and consist of the ejection of thousands of coal/rock pieces and a considerable amount of gas into a limited working space within a short period.

Physical Mechanism of Comet Outbursts: An Experimental Result
Icarus, 1993Attention is given to an experimental investigation of the physical mechanism of comet outbursts which is consistent with the general picture of mantle presence on comets and clarifies the relation of mantles to eruptive activity. The experiment and closeup observation of Comet P/Halley suggest a result different from most mathematical models in that ...

On mechanisms of the outbursts activity of comets 29P and 174P
Modern astronomy: from the Early Universe to exoplanets and black holesWe study common features in mechanisms of the outburst activity of comet 29P/Schwassmann-Wachmann 1 and asteroid (60558) Echecles, which also has a cometary designation 174P. These celestial bodies belong to the group of centaurs, whose orbits lie between the orbits of Jupiter and Neptune. An important feature of these comets is the observed brightness

Catastrophic mechanism of coal and gas outbursts and their prevention and control
Mining Science and Technology (China), 2010Abstract Based on the engineering observations of coal and gas outbursts during mining processes and the experimental results, we built a thin plate mechanical model for layered and spalled coal bodies. We studied the mechanical mechanism of outbursts, due to instability, of thin plates of coal rocks under the action of in-plane load and normal load,
