摘      要：Coal and gas outburst is a frequent dynamic disaster during underground coal mining *** about 150 years of exploration,the mechanisms of outbursts remain unclear to *** on outburst mechanisms worldwide focused on the physicochemical and mechanical properties of outburst-prone coal,laboratory-scale outburst experiments and numerical modeling,mine-site investigations,and doctrines of outburst *** mechanisms are divided into two categories:single-factor and multi-factor *** multi-factor mechanism is widely accepted,but all statistical phenomena during a single outburst cannot be explained using present *** topics about outburst mechanisms are proposed by summarizing the phenomena that need precise *** most appealing research is the microscopic process of the interaction between coal and *** physical-chemical methods can help characterize the natural properties of outburst-prone *** experiments can compensate for the deficiency of first-hand observation at the *** the original outburst scene by constructing a geomechanical model or numerical model and reproducing the entire outburst process based on mining environment conditions,including stratigraphic distribution,gas occurrence,and geological structure,are *** studies can explore outburst mechanisms at the microscale.
