Coal and gas outburst dynamic system

open access: yesInternational Journal of Mining Science and Technology, 2017
Coal and gas outburst is an extremely complex dynamic disaster in coal mine production process which will damage casualties and equipment facilities, and disorder the ventilation system by suddenly ejecting a great amount of coal and gas into roadway or working face. This paper analyzed the interaction among the three essential elements of coal and gas

Investigation of coal and gas outburst risk by microseismic monitoring. [PDF]

open access: yesPLoS One, 2019
In order to improve the monitoring and prediction of coal and gas outburst, this paper proposes a new method for dynamic regional prediction of coal and gas outburst using microseismic (MS) monitoring. The theoretical basis of this method is presented.
