Energy Action Mechanism of Coal and Gas Outburst Induced by Rockburst
The essence of both rockburst and coal and gas outburst lies in fast energy release. In order to explore the energy action mechanism of coal and gas outburst induced by rockburst in rockburst and coal and gas outburst combined mines, the split Hopkinson ...

Typical characteristics of deep coal seams with high outburst risk, outburst inducing mechanism and prevention measures [PDF]
Coal mining in China has gradually entered deep levels. With the continuous increase in mining depth, the outburst risk of coal seam has significantly increased, with both the frequency and intensity of outbursts rising noticeably, posing huge challenges

Effects of confinement and vaccination on an epidemic outburst: A statistical mechanics approach [PDF]
This work describes a simple agent model for the spread of an epidemic outburst, with special emphasis on mobility and geographical considerations, which we characterize via statistical mechanics and numerical simulations. As the mobility is decreased, a percolation phase transition is found separating a free-propagation phase in which the outburst ...
