Review of unstable falling of roof rock blocks under dynamic disturbance

工程科学学报, 2023
Roof caving has been the main threat to the safety of underground mining, in which the caving of roof rock blocks is particularly concerning. The secondary structural planes of surrounding rocks around underground excavations, such as roadways and stopes,

Correlation between tectonic CO2 Earth degassing and seismicity is revealed by a 10-year record in the Apennines, Italy

Science Advances, 2020
Massive emissions of deep CO2 coupled to the 2009–2018 Central Italy earthquakes. Deep CO2 emissions characterize many nonvolcanic, seismically active regions worldwide, and the involvement of deep CO2 in the earthquake cycle is now generally recognized.

Establishment of landslide early-warning indicator using the combination of numerical simulations and case matching method in wushan open-pit mine

Frontiers in Earth Science, 2022
Landslides seriously threaten the safety of human life and property. In order to predict the on-set of potential landslides, this paper first characterizes the physical and mechanical parameters of rock mass on the basis of core rock quality designation ...

Controlling fluid-induced seismicity during a 6.1-km-deep geothermal stimulation in Finland

Science Advances, 2019
Near–real-time seismic monitoring and injection control limits induced earthquakes in urban geothermal reservoir stimulation. We show that near–real-time seismic monitoring of fluid injection allowed control of induced earthquakes during the stimulation ...

Is Earthquake Triggering Driven by Small Earthquakes? [PDF]

, 2002
Using a catalog of seismicity for Southern California, we measure how the number of triggered earthquakes increases with the earthquake magnitude. The trade-off between this relation and the distribution of earthquake magnitudes controls the relative ...
