ABSTRACT

This study tries to create alternative vibration prediction equations considering some important and neglected blast parameters. The target research parameters are stiffness ratio, blast dimensions and free face conditions. Alternative equations were created by classifying the blasts based on operational parameters. Also, cluster analysis and discriminant analysis methods were used to classify blasts into homogenous subgroups. Nine different predictor equations were developed based on scaled distance concept. The developed predictor models are quite promising. The research shows that before the application of complex modelling techniques, all the alternative predictive models should be investigated for mining sites.

摘要

本研究试图创建考虑到一些重要但被忽视的爆炸参数的替代振动预测方程。目标研究参数是刚度比、爆炸尺寸和自由面条件。通过根据操作参数对爆炸进行分类，创建了替代方程。此外，聚类分析和判别分析方法用于将爆炸分为同质亚组。基于比例距离概念开发了九种不同的预测方程。开发的预测模型非常有前途。研究表明，在应用复杂建模技术之前，应对矿区所有替代预测模型进行研究。
