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 ...

Earthquake Predicting and Tectonic Stress Reducing Possibilities
, 2022 Abstract Recent satellite and ground-based observations prove that during the earthquake formative period VLF/LF and ULF electromagnetic emissions are observed in seismogenic areas. The present consolidated paper describes a theoretical model of the generation of electromagnetic emissions detected during the earthquake preparation periods, a ...

Mechanism for stress abnormality and rock burst in variation zone of roof-stratum thickness
Yantu gongcheng xuebao, 2023 The roof stratum structure is one of the main factors affecting coal burst, and the coal burst is also easily induced in the variation zone of roof-stratum thickness. This phenomenon is gradually severe in deep mining areas in Inner Mongolia.

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series A, 1992 In order to establish the methodology of hydraulic fracturing tectonic stress measurements, the relation between the so-called reopening pressure of longitudinal cracks and tectonic stresses is studied. To this end, the coupled problem of fluid flow in the crack and the crack reopening behavior in an impermeable rock is analyzed based on the linear ...

Seismicity, focal mechanisms, and stress distribution in the Tres Vírgenes volcanic and geothermal region, Baja California Sur, Mexico [PDF]
Geofísica Internacional, 2006 In October 1993 we carried out a seismic monitoring in the Tres Vírgenes volcanic region in order to record the background seismicity associated with the volcanic structures, the geothermal field and the tectonic features of the area. Hypocenters for 257

Impact of differential stress on fracture due to volume increasing hydration [PDF]
Solid EarthThe volume increase that accompanies many hydration reactions can stress and fracture the surrounding rock, a process commonly called reaction-induced fracturing.
