Abstract
This study focuses on predicting ground vibrations generated by blasting activities
in open cast limestone mining by integrating blast design parameters with conventional
variables. Blasting is a critical operation for the effective removal of overburden
and mineral extraction, but it can lead to significant adverse effects, particularly
ground vibrations, which pose challenges for both mining and environmental engineers.
Conventional methods for estimating these vibrations typically focus on the distance
from the blast site and the maximum charge per delay as key independent variables.
Recognizing the substantial impact of blast design on vibration levels, this research
employs multiple linear regression analysis to incorporate additional factors such
as blast design elements. By developing a more comprehensive predictive model, the
study aims to enhance the accuracy of ground vibration forecasts, ultimately contributing
to safer and more sustainable mining practices.
