A New Theoretical View of Rockburst and Its Engineering Application

Advances in Civil Engineering, 2018
Traditionally, rockburst is considered as a dynamic phenomenon of sudden destruction of coal/rock mass. In this study, rockburst is treated as an event process rather than a phenomenon. This paper introduces typical rockburst process, its classification,

Characteristics of Microseismic Generated During Shear Failure of Granite With Structural Plane of Various Connectivities

Advances in Civil Engineering, Volume 2025, Issue 1, 2025.
The structural plane significantly changes the rock failure behavior. The connectivity of the structural plane generally varies for the rocks in different engineering practices or rock environments. In this manuscript, a series of direct shear tests on granite specimens are carried out using the true‐triaxial testing machine.

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 ...

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 ...

Influence of longwall gateroad convergence on the process of mine ventilation network-model tests

International Journal of Mining Science and Technology, 2019
Hard coal mines are required to constantly ventilate mine workings to ensure that the air composition is at a certain humidity and temperature level that is comfortable for underground mine workers, especially in deep deposits.
