Energy Release Analysis of a Severe Rockburst in a Headrace Tunnel Crossing a Tectonic Stress Zone

Shock and Vibration, 2019
When tunneling in a hard and brittle rock mass within a tectonic stress zone, dynamic failure of rock mass-rockburst may occur. Considering the occurrence of rockburst is generally induced by a sudden release of storage elastic energy, a numerical ...

Inversion of multiphase tectonic stress field and fracture evolution in shale gas reservoirs [PDF]

Youqicang pingjia yu kaifa
The shale gas reserves in the Wufeng Formation-Longmaxi Formation of the Luzhou Block in southern Sichuan are substantial. Tectonic movements alter the ground stress, significantly impacting the exploration and development of shale gas.

Tectonic Stress as the Driving Mechanism for Dike Opening in an Oblique Rift Setting: A Deformation Model of the 2021 Fagradalsfjall Dike, Iceland

Geophysical Research Letters
Repeated dike‐intrusions often occur in zones where extensional stress has accumulated. Still, geodetic modeling of observed dike‐induced ground deformation often ignores the contribution of tectonic stress. On the obliquely spreading Reykjanes Peninsula,

Present-day stress state of the Shanxi tectonic belt [PDF]

Geodynamics & Tectonophysics, 2012
The Shanxi tectonic belt is a historically earthquakeabundant area. For the majority of strong earthquakes in this area, the distribution of earthquake foci was controlled by the N–S oriented local structures on the tectonic belt. Studies of the present stress state of the Shanxi tectonic belt can contribute to the understanding of the relationship ...

Estimates of vertical tectonic stress in the northwest Ethiopian plateau using topography and gravity data [PDF]

Heliyon
The northwest Ethiopian plateau is one of the globe's most complex tectonic zones. Within the area, the previous geological and geophysical investigations revealed volcanism and deformation effects but did not thoroughly examine crust movement, isostatic

Effect of Deviatoric Stress on Deformation Energy of Tectonic Coal: A Modified Energy Model Considering Nonlinearity

Energy Science & Engineering
The deformation energy stored in soil‐like tectonic coal plays a critical role in coal and gas outbursts. Unlike hard rocks, tectonic coal exhibits pronounced stress–strain nonlinearity, invalidating traditional elastic energy models.

Remote-sensing of tectonic-induced stress across faults using high energy muon beams

Physical Review Research
We illustrate a theoretical study of a technique using high-energy muon beams (TeV class) propagating through thick (kilometer-long) crystalline rock layers subject to tectonic-induced stress, potentially capable of actively monitoring the temporal ...

Controlling effect of tectonic stress field on coal and gas outburst

Meitan xuebao, 2023
To investigate the controlling effect of tectonic stress field on coal and gas outburst, the gas geology, tectonophysics and rock mechanics methods were applied to analyze the influences of tectonic stress field on tectonic coal, in-situ stress and coal ...

RECONSTRUCTION OF TECTONIC STRESSES ON THE SCHMIDT PENINSULA (SAKHALIN) [PDF]

Bulletin of Kamchatka Regional Association «Educational-Scientific Center». Earth Sciences, 2021
The article presents data on the stress state of the Schmidt Peninsula of Sakhalin Island, obtained as a result of field tectonophysical studies in 2020. The importance of studying the northern part of Sakhalin is due to the prospects of this region for the minerals search.

Insights into fundamental problems of rockburst under the modern structure stress field

Scientific Reports, 2022
Rockbursts are some of the most severe dynamic disasters in coal mines. In this paper, the discrimination method of the tectonic stress field is proposed by analyzing the modern stress field in China.
