Influence of dynamic disturbance on rock creep from time, space and energy aspects

open access: yesGeomatics, Natural Hazards & Risk, 2022
In order to explore the influence of dynamic disturbance on creep behavior of rock, the creep damage evolution in rock under the dynamic disturbance are reproduced with creep damage model.

Review: Induced Seismicity During Geoenergy Development—A Hydromechanical Perspective

open access: yesJournal of Geophysical Research: Solid Earth, 2022
The basic triggering mechanism underlying induced seismicity traces back to the mid‐1960s that relied on the process of pore‐fluid pressure diffusion. The last decade has experienced a renaissance of induced seismicity research and data proliferation. An

A Numerical Model for the Compressive Behavior of Granular Backfill Based on Experimental Data and Application in Surface Subsidence

open access: yesMetals, 2022
Granular backfill is generally confined in stopes to bear underground pressure in metal mines. Its mechanical behavior under lateral confinement is vital for controlling stope wall behavior and estimating surface subsidence in backfill mining operations.

Experimental and Numerical Study on the Anchorage Effect of Bolted Jointed Rock Masses

open access: yesFrontiers in Earth Science, 2022
Anchor technology has become an irreplaceable geotechnical engineering reinforcement measure. To clarify anchorage effects and investigate the three-dimensional (3D) crack propagation process of bolted jointed rock masses, a series of physical model ...

A model for rock dissipated energy estimation based on acoustic emission measurements

open access: yesFrontiers in Earth Science, 2023
The temporal domain of dissipated energy during rock damage and failure is commonly quantified using loading and unloading tests or elastic mechanics-based theoretical calculation methods. However, these approaches cannot be applied to obtain the spatial

Multi-fracture interactions during two-phase flow of oil and water in deformable tight sandstone oil reservoirs

open access: yesJournal of Rock Mechanics and Geotechnical Engineering, 2020
Tight oil reservoirs are complex geological materials composed of solid matrix, pore structure, and mixed multiple phases of fluids, particularly for oil reservoirs suffering from high content of in situ pressurized water found in China.

Fractal Seismicity and Seismic Risk [PDF]

open access: yesIzvestiya, Physics of the Solid Earth, 2020
Recently, attempts have been made to take into account the fractal properties of seismicity when mapping the long-term rate of earthquakes. The paper touches upon the theoretical aspects of fractality and provides a critical analysis of its applications to the problems of seismic ...

Hydraulic Fracturing‐Induced Seismicity

open access: yesReviews of Geophysics, 2020
Hydraulic fracturing (HF) is a technique that is used for extracting petroleum resources from impermeable host rocks. In this process, fluid injected under high pressure causes fractures to propagate.

Stope structure evaluation based on the damage model driven by microseismic data and Mathews stability diagram method in Xiadian Gold Mine

open access: yesGeomatics, Natural Hazards & Risk, 2021
To obtain a better economic benefit, Xiadian Gold Mine intended to increase the stope structure parameter from 2.5 m (height) to 8 m. A test stope using the new structure parameter was mined to verify the surrounding rock’s stability.
