Prediction of peak particle velocity and peak air pressure generated by buried explosion
International Journal of Mining and Geological Engineering, 1988Three sets of different formulae expressed as functions of dynamic elastic constants of rock and some design parameters involved in a buried explosion are derived explicitly for the prediction of peak particle velocity (PPV) and peak air pressure (PAP).

Prediction of peak particle velocity using multi regression analysis: case studies
Geomechanics and Geoengineering, 2016ABSTRACTGround vibrations produced from blasting operations cause structural vibrations, which may weaken structure if it occurs at the resonant frequency. Measurable parameters associated with ground vibrations are peak particle velocity (PPV), amplitude and dominant frequency (frequency of highest PPV amongst translational, vertical and horizontal ...

Statistical reliability of forecasting peak particle velocity under large-scale production blasting
Journal of Mining Science, 2015The authors review methods to assess reliability of forecasting of peak vibration velocities under large-scale production blasting using statistical analysis of regression residuals. The regression analysis of experimental data and the subsequent statistical analysis of the regression residuals is exemplified.

Estimation of peak particle velocity using soft computing technique approaches: a review
Noise & Vibration Worldwide, 2018Ground vibrations caused by blasting are undesirable consequences in the mining industry. It can cause serious damage to the nearby buildings and facilities. Hence, such vibrations have to be controlled to reduce the damage to the environment, and this may be achieved by predicting the blast peak particle velocity.

Classification and regression tree technique in estimating peak particle velocity caused by blasting
Engineering with Computers, 2016Blasting is a widely used technique for rock fragmentation in surface mines and tunneling projects. The ground vibrations produced by blasting operations are the main concern for the industries undertaking blasting operations, which can damage the surrounding structures, adjacent rock masses, roads and slopes in the vicinity.

Abstract Peak particle velocity (PPV) is the most basic and direct parameter of vibration event to connect with stress increment, so they are studied in this paper through statistics and analysis. The vibration events in underground coal mine can be divided into whole mine (WM) event, working face (WF) event and heading face (HF) event, and the WM ...

Development of a model to predict peak particle velocity in a blasting operation
International Journal of Rock Mechanics and Mining Sciences, 2011Ground vibrations arising from rock blasting is one of the fundamental problems in the mining industry, and predicting it plays an important role in the minimization of environmental complaints. To evaluate and calculate the blast-induced ground vibration by incorporating blast design and rock strength, artificial neural networks (ANN) and dimensional ...

Application of cuckoo search algorithm to estimate peak particle velocity in mine blasting
Engineering with Computers, 2016Ground vibration is one of the most undesirable effects of blasting operation in surface mines. Therefore, it seems that the prediction of ground vibrations with a high degree of accuracy is necessary to reduce environmental effects. This article proposes a novel swarm intelligence algorithm based on cuckoo search (NSICS) to create a precise equation ...

I would like to suggest a theoretical justification for the mathematical structure of some laws for predicting the maximum particle velocity vibration from blasting operations in the light of some basic notions of elastic and anelastic wave theory. Within this point of view, in dimensionally correct expressions, the terms pertaining to the rock, to the
