We report laboratory experiments to investigate the dynamic failure characteristics of
outburst‐prone coal using a split Hopkinson pressure bar (SHPB). For comparison, two …

Coal and gas outburst is a kind of complex dynamic disaster with short duration and strong
explosiveness, and the modes and strength of the outburst are determined by the in situ …

Understanding the dynamic mechanical behaviors and microstructural properties of outburst-
prone coal is significant for preventing coal and gas outbursts during underground mining. In …
