A self-supervision rockburst risk prediction algorithm based on automatic mining of rockburst prediction index features

Frontiers in Earth Science
The rockburst risk prediction based on microseismic (MS) data is an important research task in deep mine safety prevention. However, the lack of systematic research on explicit prediction indexes and the waste of a large amount of unlabeled data are ...

Geologic and tectonic characteristics of rockbursts [PDF]

, 1995
The modern mining enterprises have attained such scales of engineering activity that their direct influence to a rock massif and in series of cases to the region seismic regime doesn`t provoke any doubts. Excavation and removal of large volumes of rock mass, industrial explosions and other technological factors during long time can lead to the ...

Research on Stress Characteristics of Rockburst in Over-Length Deep-Buried Tunnel

Buildings
As a unique geological hazard in a high-geo-stress environment, rockburst happens with strong suddenness, randomness, and destructiveness, but the mechanism of its occurrence in a deep-buried tunnel in a high-geo-stress environment needs further study ...
