A New Method to Predict Shock-Type Coal-Gas Outburst Disaster and Its Application

Geofluids, 2023
Coal-gas outburst is the one of most serious coal mine dynamic disasters which affects safety mining, with 39 deaths reported during 2019 in China. The mechanism of coal-gas outbursts is complex, and the prediction methods are immature at present.

Energy principle of simulation experiments on coal and gas outburst

Meitan xuebao, 2023
Coal and gas outburst is an extremely destructive gas dynamic disaster in mines. Since such dynamic disasters are usually difficult to observe directly, physical similarity simulation of coal and gas outburst has become an important method for collecting

Possible Mechanisms for Cometary Outbursts [PDF]

International Astronomical Union Colloquium, 1991
Abstract.A cometary outburst is an unexpected flare-up in the brightness of a comet, with the brightness normally increasing by 2 to 3 magnitudes, but on occasion by up to 5. This outburst is superimposed on the general change in brightness that is related to the comet’s heliocentric and geocentric distance, spin phase, spin axis orientation and ...
