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

open access: yesGeofluids, 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.

Response characteristics of gas pressure under simultaneous static and dynamic load: Implication for coal and gas outburst mechanism

open access: yesInternational Journal of Mining Science and Technology, 2023
Coal and gas outbursts are dynamic disasters in which a large mass of gas and coal suddenly emerges in a mining space within a split second. The interaction between the gas pressure and stress environment is one of the key factors that induce coal and ...
