Impact of Elevation on Blasting Vibration Frequency in an Open Pit

摘要

A large number of experimental data show that the elevation has an important influence to the master frequency of blasting. There was little research which considers relations between elevation and master frequency in the past, but it has theoretical and practical significances to the practical engineering. This paper firstly conducts the research of open-pit blasting vibration, and then gives a formula of master frequency attenuation which fits the geological conditions of blasting area based on regression. Thus it has accurate forecasting and judgments to the opencast blasting vibration.
