The Research of Coal and Gas Outburst Warning Based on Logistic Regression and Geographic Information System

Shock and Vibration, 2021
Coal and gas outburst is one of the major disasters in the safety production of coal mine. According to the mechanism of coal and gas outburst, based on the comprehensive analysis of various influencing factors of coal and gas outburst, with the ...

Destabilization of the hard coal microstructure by a weak electric field [PDF]

, 2018
This study aims to analyse physical and chemical changes in hard coal samples under the influence of low-intensity electric fields in comparison to the fragments of ejected coal, as well as the coal samples selected from the zones ...

Prediction of coal and gas outburst based on catastrophe progression method

Gong-kuang zidonghua, 2015
In view of problem that inner mechanism of coal and gas outburst was very complex and it was difficult to establish an appropriate multivariate nonlinear prediction model, prediction method of coal and gas outburst based on catastrophe progression method

Black hole X-ray transients: mass accumulation in the disk - constraints for the viscosity [PDF]

, 2001
The outburst cycles of black hole X-ray transients are now generally understood as caused by a thermal instability in the accretion disk, the same mechanism as in dwarf novae outbursts.

Consistent accretion-induced heating of the neutron-star crust in MXB 1659-29 during two different outbursts [PDF]

, 2018
Monitoring the cooling of neutron-star crusts heated during accretion outbursts allows us to infer the physics of the dense matter present in the crust. We examine the crust cooling evolution of the low-mass X-ray binary MXB 1659-29 up to ~505 days after

Effects of confinement and vaccination on an epidemic outburst: A statistical mechanics approach [PDF]

Physical Review E, 2021
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 ...

Flux Relaxation after two outbursts of the magnetar SGR 1627$-$41 and possible hard X-ray emission

, 2018
We report on the long-term flux relaxation of the magnetar SGR 1627-41 after its 2008 outburst, and evidence for hard X-ray excess measured with NuSTAR.

The 2008 outburst of EX Lup - silicate crystals in motion [PDF]

, 2011
EX Lup is the prototype of the EXor class of eruptive young stars. These objects show optical outbursts which are thought to be related to runaway accretion onto the star.

65. On the mechanism of solar outbursts [PDF]

Symposium - International Astronomical Union, 1957
Today it is taken for granted that the solar outbursts are produced by plasma oscillations of coronal matter, excited by a corpuscular radiation originating in the inner corona (Pawsey and Smerd, 1953) [1]. A certain component of this corpuscular radiation is obviously identical with that generating geomagnetic storms.

Recent advances on mechanism and prevention technology of coal and gas outburst disasters in China

Meitan kexue jishu
Coal and gas outburst is a kind of mine dynamic disaster that occurs in underground coal mines, often causing mass casualties and seriously restricting the safe and efficient production of coal mines.
