Support Design for Mines Exposed to Rockburst Hazard

Аннотация

One of the approaches to reducing aftereffects of rock bursts is the dynamic support capable to stand strong dynamic rock pressure events in the form of seismic vibration and failure of adjacent rock mass. The article describes the support design procedure in use in hard mineral mines exposed to rockburst hazard. Different types of rock bolting and surface support are discussed from the viewpoint of energy absorption and yielding.
