Impact of Blasting Activities on Ground Vibrations: Insights from Micromate Measurements in Limestone Mining
摘要
This research investigates the impact of vibrations produced by blasting activities at a limestone mine, focusing on vibration analysis and experimental characterization using the Micromate tool. The major purpose of this research is to understand the vibrations arising from blasting, analyze the influence of different blast parameters on variations in Peak Vector Sum (PVS) values, and evaluate the effect on the surrounding environment, particularly structures near the mining location. The research method involves vibration measurements using Micromate, allowing for accurate data collection. The research also aims to evaluate the variations in vibration levels between controlled blasting and conventional blasting, a comparative analysis of blasting procedures was also carried out. Additionally, in order to reduce excessive ground vibrations and guarantee efficient fragmentation, blasting parameters were optimized by examining the effects of burden, spacing, and explosive charge. According to the study’s findings, controlled blasting produces lower PVS values than traditional techniques, which lessens the possibility of harming adjacent structures. Vibrations can be greatly reduced without sacrificing blasting efficiency by modifying explosive charge per hole and spacing, as further evidenced by blasting parameter optimization. These findings aid in the creation of better vibration control techniques, guaranteeing safer and more environmentally friendly mining operations.
