Excavation of openings in underground mines and tunnels has gradually been extended to great depths in the Earth’s crust to meet increasing requirements for mineral resources and underground spaces. The deepest underground excavation now operates mines with depths exceeding 4 to 5 km, and the deep excavations at depths greater than a thousand meters are often in rock engineering. These deep excavations (underground depth from 1 to 5 km) are faced with some unconventional failure phenomena, such as rockbursts, slabbing, large deformation, and zonal disintegration, which present significant differences from rock failure around shallow openings. In particular, the rockburst hazard – a sudden failure of rocks accompanied with violent ejections of rock fragments and rapid release of energy stored in highly compressed rocks – poses a serious threat to the safety of mining and tunneling operations.
Stress conditions in deep rocks are typically characterized by combined static and dynamic loads, consisting of the excavation-induced high stress concentration around openings and strong dynamic disturbances from drilling and blasting, excavation unloading, roof caving, and fault slippage. The combined static and dynamic stress conditions exert key controls on the onset and development of rockbursts. However, it remains a significant challenge to fully understand the mechanisms of rockbursts and to prevent the occurrence of rockbursts in field practice.
This Special Issue aims to collate original research and review articles encompassing theoretical analyses, in-situ experiments, laboratory experiments, and numerical simulations concerning the monitoring, mechanism, and mitigation of rockbursts in deep rocks.
Potential topics include but are not limited to the following:
- Laboratory experiments characterizing rock properties related to the proneness of rockbursts
- Comprehensive evaluation of the risk of rockbursts in deep excavation
- Discovery, identification, and theoretical formulation of mechanisms for rockbursts
- Characterization of field geological conditions prone to rockbursts
- Forecasting of rockbursts using microseismic monitored data
- Development and application of mitigation measures against rockbursts
Papers are published upon acceptance.
