Prediction of peak particle velocity using hybrid random forest approach. [PDF]
Sci RepAbstractBlasting excavation is widely used in mining, tunneling and construction industries, but it leads to produce ground vibration which can seriously damage the urban communities. The peak particle velocity (PPV) is one of main indicators for determining the extent of ground vibration.

Peak particle velocity data acquisition for monitoring blast induced earthquakes in quarry sites. [PDF]
Data Brief, 2018 The peak particle velocity datasets recorded during quarry blasts in the neighborhood villages and towns in Ibadan and Abeokuta were processed and analyzed in order to recommend a safe blast design for each of the quarries. The minimum peak particle velocity of 48.27 mm/s was recorded near the foundation of the nearest residence at the shot to ...

Predicting peak particle velocity in pre-splitting of gas-producing devices using improved particle swarm optimization algorithm. [PDF]
Sci RepAdvance prediction and control of vibration velocity during blasting construction is essential to protect the tunnel and surrounding buildings. In this study, we propose an Improved Particle Swarm Optimization (IPSO) Backpropagation (BP) Neural Network Model (IPSO-BP) considering the effect of frequency (f) to provide a highly accurate prediction tool ...

Discussion on the Discreteness of the Attenuation Parameters of the Peak Particle Velocity Induced by Blasting. [PDF]
Sensors (Basel)The research on the attenuation law of blasting vibration has become the foundation and precondition of the effective control of blasting vibration damage. Aiming at the characteristics of low frequency, low velocity, and strong amplitude of the R wave, an improved wave component separation method based on R wave suppression is proposed.

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.

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 ...

Computation of Surface Wave Parameters and Peak Particle Velocity
Journal of Structural Technology, 2023 In recent times, the rise in terrorist activities has underscored the critical need for designing structures with blast resistance capabilities. However, many Indian codes currently in place do not adequately address the issue of blast loads. This knowledge gap poses a significant challenge to engineers who must ensure the safety and security of ...

Predicting the peak particle velocity from rock blasting operations using Bayesian approach [PDF]
Acta Geophysica, 2022 AbstractMeasuring the blast-induced ground vibration at blasting sites is very important, to plan and avoid adverse effects of blasting in terms of the peak particle velocity (PPV). However, the measurement of PPV often requires time, cost, and logistic commitment, which may not be economical for small-scale mining operations.

International Journal of Engineering, Science and Technology, 2011 Damage to the surrounding rock during blasting either in underground or surface excavation, is a growing concern today. It has been found that the integrity of rockmass is reduced significantly from pre to post blast condition due to disregard paid to the surrounding rockmass.
