Time-dependent deformation and fracture evolution around underground excavations

Geomatics, Natural Hazards & Risk, 2020
A numerical time-dependent deformation model of rock by incorporating the stress corrosion model into a three-dimensional discrete element code was established to investigate time-dependent deformation and fracture evolution of surrounding rock around ...

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 ...

Seismicity and Principal Seismic Effects [PDF]

Geophysical 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,

Effect of linguistic framing and information provision on attitudes towards induced seismicity and seismicity regulation [PDF]

, 2022
Shale gas is an expanding energy source worldwide, yet ‘fracking’ remains controversial. Amongst public concerns is induced seismicity (tremors). The UK had the most stringent induced seismicity regulations in the world, prior to instating a moratorium ...

Regional variations in the diffusion of triggered seismicity [PDF]

, 2005
We determine the spatiotemporal characteristics of interearthquake triggering in the International Seismological Centre catalogue on regional and global scales. We pose a null hypothesis of spatially clustered, temporally random seismicity, and determine

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

International 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.

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

Geomatics, 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.

Stylolite fractal characteristics and the influence of stylolite on strength of limestone

工程科学学报, 2017
To study the fractal characteristics of stylolite and its influence on the strength of limestone, the fractal dimension of horizontal stylolite and vertical stylolite was analyzed using the power spectral density method and the digital image box ...
