Time-Varying Characteristics of Granite Microstructures after Cyclic Dynamic Disturbance Using Nuclear Magnetic Resonance

open access: yesCrystals, 2017
To investigate the variation in the characteristics of rock microstructure after cyclic dynamic disturbances, a split Hopkinson pressure bar (SHPB) was used to carry out cyclic dynamic impact tests on granite, and the P-wave velocity was used as the ...

Wave disturbance filtering in dynamic positioning systems [PDF]

open access: yesModeling, Identification and Control, 1996
Three different approaches to wave disturbance filtering in dynamic positioning systems are studied in this paper. It is shown that a conventional design based on notch filters leads to approximately the same achievable performance of the total control ...

Failure and instability mechanism of anchored surrounding rock for deep chamber group with super-large section under dynamic disturbances

open access: yesRock and Soil Mechanics, 2021
The interaction of super-large section chamber group in deep and close-distance condition will lead to stress concentration and wide failure range of surrounding rock, especially under dynamic disturbances.

Development and application of multifunctional shear test apparatus for rock discontinuity under dynamic disturbance loading

open access: yesRock and Soil Mechanics, 2022
Dynamic disturbance is an important influence factor that causes the sliding instability of rock discontinuity and then triggers strong dynamic geological disasters, such as earthquakes and rock bursts.

Review of unstable falling of roof rock blocks under dynamic disturbance

open access: yes工程科学学报, 2023
Roof caving has been the main threat to the safety of underground mining, in which the caving of roof rock blocks is particularly concerning. The secondary structural planes of surrounding rocks around underground excavations, such as roadways and stopes,

Effect of Different Tunnel Distribution on Dynamic Behavior and Damage Characteristics of Non-Adjacent Tunnel Triggered by Blasting Disturbance

open access: yesMathematics, 2022
When a blasting is executed near two tunnels, the blasting wave will trigger a dynamic response and damage to the tunnels. Depending on the tunnel distribution, the path of the blasting wave to the remote non-adjacent tunnels will change. The aim of this
