Macroscopic fracture mechanism of coal body and evolution characteristics analysis of impact force in deep coal and gas outburst

open access: yesScientific Reports, 2023
With the increase of mining depth and intensity, coal and gas outburst dynamic disasters occur frequently. In order to deeply study the macroscopic fracture mechanism of coal body and evolution characteristics analysis of impact force, taking the ...

X-ray outbursts of low-mass X-ray binary transients observed in the RXTE era

open access: yes, 2015
We have performed a statistical study of the properties of 110 bright X-ray outbursts in 36 low-mass X-ray binary transients (LMXBTs) seen with the All-Sky Monitor (2--12 keV) on board the {\it Rossi X-ray Timing Explorer} ({\it RXTE}) in 1996--2011.

Resumption of mass accretion in RS Oph [PDF]

open access: yes, 2007
The latest outburst of the recurrent nova RS Oph occurred in 2006 February. Photometric data presented here show evidence of the resumption of optical flickering, indicating re-establishment of accretion by day 241 of the outburst.

Failure Mechanism of Coal and Gas Outburst Initiation

open access: yesProcedia Engineering, 2011
Abstract Based on the concept that the initiation of coal and gas outburst is the failure of coal and rock mass, the relevant stability theory is applied to build a nonlinear dynamics model of outburst initiation, and the failure mechanism of outburst initiation is systematically analyzed.

INTEGRAL study of temporal properties of bright flares in Supergiant Fast X-ray Transients [PDF]

open access: yes, 2016
We have characterized the typical temporal behaviour of the bright X-ray flares detected from the three Supergiant Fast X-ray Transients showing the most extreme transient behaviour (XTEJ1739-302, IGRJ17544-2619, SAXJ1818.6-1703).

Study on cause of coal and gas outburst accident based on D-S evidence theory and Bayesian network

open access: yesMeikuang Anquan, 2023
To explore the mechanism and influencing factors of coal and gas outburst accidents in coal mines, the factors inducing coal and gas outburst accidents were selected from four aspects: human, machine, environment and management, and the risk of accidents
