Development of a New Laboratory Technique for Reducing the Peak Particle Velocity Arising from the Blast [PDF]
International Journal of Economic and Environment Geology, 2017 Certain vibrational waves are formed as a result of open quarry blasts. The peak particle velocity occurred by these waves provides that structures and people present around the blast point are negatively affected.

Calculation of Peak Particle Velocity Caused by Blasting Vibration in Step Topography [PDF]
Journal of Engineering and Technological Sciences, 2018 High ground vibrations not only adversely affect the integrity of the structures in a mine area but also create inconvenience for the nearby population. In order to protect the Sanyou Mine slope in Tangshan, China from blasting vibration, the peak particle velocity in step topography must be accurately calculated. At present, the reflection coefficient

Development and applications of two and three component particle image velocimetry techniques for simultaneous measurement in multi-phase flows and automative fuel sprays [PDF]
, 2010 The introduction of a new imaging approach for simultaneous multi-phase and multi-constituent velocity measurements is the main focus of this research. The proposed approach is based on the use of a single off-the-shelf colour camera which will enable ...

ANALISIS GROUND VIBRATION DENGAN METODE PEAK PARTICLE VELOCITY (PPV)
Faktor Exacta, 2021 <p><em>Measurement of Peak Particle Velocity (PPV) mm / sec in the Sabo dam construction project was carried out using seismic accelerometers. This study is to determine the value of PPV produced by construction equipment and then compared with the BS 6472-2: 2008 standard. The measurement method is carried out based on the applicable rules.

Journal of Marine Science and Engineering, 2021 The water particle velocity of the wave peaks is closely related to the wave load borne by offshore structures. It is of great value for marine disaster prevention to study the water particle velocity of nonlinear extreme waves represented by Freak waves.

Rock blasting — peak particle velocity against distance [PDF]
Proceedings of the Ninth Symposium on Field Measurements in Geomechanics, 2015 The potential damage which could be induced by blasting in rock is normally evaluated with reference to the peak particle velocity (PPV). It is well-known that closer distances lead to higher PPV values. In some cases, due to muck handling logistics, the ramps forming the access result in different elevations across the different parts of a very deep ...

Directed transport of a deformable particle in confined periodic structures
New Journal of Physics, 2022 Directed transport of a deformable particle is numerically investigated in a two-dimensional periodic channel. Unlike the rigid particle, the deformable particle can pass through the channel bottleneck that is significantly smaller than the particle size.
