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

open access: yesFrontiers 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 ...

A hybrid recognition model of microseismic signals for underground mining based on CNN and LSTM networks

open access: yesGeomatics, Natural Hazards & Risk, 2021
Microseismic (MS) monitoring technology has been widely used to monitor ground pressure disasters. However, the underground mining environment is complex and contains many types of noise sources.

Integrated simulation and monitoring to analyze failure mechanism of the anti-dip layered slope with soft and hard rock interbedding

open access: yesInternational Journal of Mining Science and Technology, 2023
The significant difference between the mechanical properties of soft rock and hard rock results in the complexity of the failure mode of the anti-dip layered slope with soft and hard rock interbedding.

Seismicity and Principal Seismic Effects [PDF]

open access: yesGeophysical Journal International, 1970
Summary A statistical method is given for estimating the total effect of earthquakes over a given period. The effect may be measured by return-time, shaking or damage, and may be exerted at a point (e.g. building), on a linear object (e.g. road), or on an area. For each type of effect there are given formulae for the statistical distribution,

Heterogeneous Fracture Slip and Aseismic‐Seismic Transition in a Triaxial Injection Test

open access: yesGeophysical Research Letters, 2020
Fault/fracture slip and seismicity caused by fluid injection are of major interest to subsurface science and engineering. However, some fundamental aspects of the temporal and spatial evolutions of induced seismicity remain unresolved.

Dual Seismic Migration Velocities in Seismic Swarms

open access: yesGeophysical Research Letters, 2021
AbstractFluid‐induced earthquake sequences generally appear as expanding swarms activating a particular fault. The recent analysis of a swarm in the Corinth rift has revealed a dual migration pattern, with a global slow expansion (m day−1) and episodes of rapid migration (km day−1).

Induced Seismicity Reduces Seismic Hazard? [PDF]

open access: yesGeophysical Research Letters, 2019
AbstractEarthquakes caused by human activities have been observed for decades. Often these are related to industrial activities pumping fluids into deep geologic formations, like with wastewater disposal. The simplest theory connecting these processes to earthquakes is straightforward: injection leads to fluid pressure changes that either reduce the ...

A prediction model for surface deformation caused by underground mining based on spatio-temporal associations

open access: yesGeomatics, Natural Hazards & Risk, 2022
Accurate predictions of the surface deformation caused by underground mining are crucial for the safe development of underground resources. Although surface deformation has been predicted by artificial intelligence (AI) methods, most AI models are ...
