Although in recent years many new types of support components and materials have been developed to prevent structure failures in underground mines, casualties are still frequent when dynamic areas are encountered, thereby presenting great challenges to practitioners. Dynamic ground supports are designed with characteristics in relation to the dynamic responses of rock/coal in underground excavations. Activities such as drilling or blasting and improper roadway layouts are very likely to cause rock bursts, and so the role of dynamic ground support is to counteract the seismic energy rock bursts can impose.

Nowadays, it is still difficult to adequately specify where, when, and how a dynamic-induced event occurs from the perspective of rock/coal mass, as neither current seismic monitoring nor numerical modelling are able to produce reliable predictions. Nevertheless, proper design of dynamic ground support can provide a solution. Dynamic support requires that the support system should be strong, tough, yielding, and compatible enough that the majority of the kinetic seismic energy released from the rock/coal mass can be absorbed. Current research with laboratorial tests and in situ application of supporting components is not sufficient to guide the countermeasures in dynamic underground mining activities. Therefore, it is necessary to continue studying the mechanical reactions of supports under dynamic environments and to propose new components with trustworthy capabilities.

This Special Issue will be focused on reporting original research articles on the latest findings with regard to the dynamic characteristics of support components or rock/coal masses under various dynamic conditions. Furthermore, to bridge the gap between laboratory tests and actual mining activities, integrated studies concerning both these aspects are welcomed. We welcome both original research and review articles.
