Coal and gas outburst is a frequent dynamic disaster during underground coal mining activities. After about 150 years of exploration, the mechanisms of outbursts remain unclear to date. Studies on outburst mechanisms worldwide focused on the physicochemical and mechanical properties of outburst-pron...
