... ABSTRACT Seismicity can be induced by rock failures or slips along geologic structures around mine workings. Depending on their intensity and proximity to the working area, seismic events may raise safety concerns in underground mining operations. However, the geological and mining parameters...

... generated by a seismic event (particularly in the near field). Still, it represents a scaled-distance relationship, which can be correlated to the rockburst damage. The most severe rockburst damages were encountered on Level 38 of the cross-cut south, consisting mainly of sidewall and hanging wall ejections...

... as they damage excavations, mining equipment and infrastructures, delay production and cause injuries or even deaths of mining personnel. We analyzed the source mechanisms of large mining-related seismic events (M L 1.0 − 2.5) that caused damage to stopes in Siphumelele Platinum Mine. This study attempts...

... a new faulting in the near field of an underground opening. Both fault slippage and faulting generate seismic waves that propagate from the hypocenter outward in the rock mass. It was observed that rockbursts are induced by a seismic event when the seismic waves arrive at the free surface...

... fluid injection period was first analysed using the k-means clustering model, which identified two clusters associated with the injection wells studied. Based on the clustered seismic events, the geometry of the injected fluid flow was estimated using the spatial density of seismic events. A statistical...

... and stress fields play an important role in relation to the seismic responses. As the tunnels were built, various relevant seismic events occurred that affected the working strategy. The Figure 1 shows a summary of the rockburst that affected the main infrastructure tunnels. A brief description is provided...

... ABSTRACT: High-stress environments have become more common in recent years as mines are getting deeper every time. These environments imply an increase in the seismic hazard generated by the sudden release of energy from mining activities. Seismic events which cause visible damage...

... mines. Sill pillars, or diminishing pillars, experience a significant increase in mining induced stress that has resulted in extensive seismicity, including some major seismic events. A large number of mitigation strategies, including both strategic and tactical control measures, have been developed...

Through our investigations, we find that the competition between the fluid pressurization and mechanical stress transfer associated both to pressurization and co-seismic rupture is a viable mechanism for seismic events...

... ABSTRACT: Damaging seismic events in mines can have a significant impact on safety and production, therefore it is important to understand these events to help prevent or mitigate the effect in future. Seismicity is caused by changing stress conditions in the local volume of rock. Studying...
