Numerical Analyses on the Stability of a Deep Coalmine Roadway Passing through a Fault Zone: A Case Study of the Gugui Coalfield in China

open access: yesEnergies, 2021
Massive deformation often occurs when deep coalmine roadways pass through a fault zone due to the poor integrity of rock mass and high tectonic stress.

The structure and possible origins of stacking faults in gamma-yttrium disilicate [PDF]

open access: yes, 2009
Parallel stacking faults on (010) planes are frequently observed in hot-pressed Y2Si2O7. A combination of conventional dark-field imaging and high-resolution transmission electron microscopy was used to investigate the structure of these faults and it ...

Two models of hydrocarbon deposits formation in the South Caspian and Middle Kura Depressions

open access: yesГеофизический журнал
The model for the formation of hydrocarbon deposits in the South Caspian and Middle Kura depressions, despite a detailed study of the problem using geophysical and geochemical methods, remains a subject of debate.

Detection of inter-turn faults in multi-phase ferrite-PM assisted synchronous reluctance machine [PDF]

open access: yes, 2019
Inter-turn winding faults in five-phase ferrite-permanent magnet-assisted synchronous reluctance motors (fPMa-SynRMs) can lead to catastrophic consequences if not detected in a timely manner, since they can quickly progress into more severe short-circuit

The use of technology of separating horizontal wells into sections by packers in conjunction with a new geological structure concept of deposits 302-302 of the Romashkino Field

open access: yesGeoresursy, 2018
The work considers deposits 302-303 of the Bashkirian and Serpukhovian stages. The Kuakbashsky deposits 302-303 are confined to the carbonate layer of the Bashkirian and Serpukhovian sediments of the Middle and Lower Carboniferous, with various types of ...

Raman Spectral Shifts in Naturally Faulted Rocks

open access: yesGeochemistry, Geophysics, Geosystems, 2021
Raman spectral shifts of carbonaceous materials arising from faulted rocks produce varied and complex results. By analyzing faulted and adjacent non‐faulted samples from three discrete localities in France, Italy, and Morocco, we assess changes in ...
