An equivalent method for blasting vibration simulation
Simulation Modelling Practice and Theory, 2011Abstract Due to the complicated blasting load, the diversified medium models and various constitutive relations of the rock mass, and a huge job for simulating blasting of multiple holes, it is very difficult and costly to simulate the blasting vibration accurately in numerical computation. This paper presents an equivalent simulation method so as to

<p>Blasting operations in quarries are accompanied by ground vibrations which can endanger buildings nearby. A production blast is made of several holes with a small distance to each other, which are blasted with a time delay, for the purpose of production and to reduce the ground vibrations.

The Prediction of Blast Vibration
Applied Mechanics and Materials, 2013Blasting on large mounts of experiments, we construct mathematical model of seismic wave of blast with systems response method and predict waveform of blast seismic wave. The model can reflect the influence of seismic wave from several kinds of factors and can simulate the attenuation low of amplitude and frequency in the whole process of blast seismic

Abstract A hybrid method for modelling the time history of blast vibrations from production blasts is developed. The seismic signal produced by the detonation of a single hole charge is recorded in situ. This record contains information about the complex mechanism of radiating seismic energy from an explosive source as well as the filtering effect of

The Influence of Burden on Blast Vibration
Fragblast, 2001There is a common belief within the blasting community that increasing the burden will increase the blast vibration. In order to test this belief in a direct sense, it would be desirable to fire single blastholes with various burdens and monitor the vibrations at many locations.

Prediction and measurements of blast vibrations
International Journal of Surface Mining, Reclamation and Environment, 1993ABSTRACT Imminent ground vibrations are often an undesirable by-product of blasting. The “peak particle velocity” (PPV) of vibrations is often used as a means of predicting and/or assessing blast-induced damage The common prediction models for vibration incorporate the quantity of explosive per delay, without giving any consideration to its degree of ...

Blasting-induced vibration in tunnelling
Tunnelling and Underground Space Technology, 1994Abstract This paper identifies the parameters that influence vibration generated by rock blasting, and specifically considers blast design relative to large-section tunnels. The paper discusses ways of modifying round blasting so as to reduce the initial vibration level.
