Full‐Scale Tests for Assessing Blasting‐Induced Vibration and Noise

Abstract

Vibration and noise problems caused by a number of construction processes, specifically blasting for infrastructure development, are becoming important because of their civil appeal. In this study, a square root equation (SRE) with a 95% confidence level was proposed for predicting blasting-induced vibration through full-scale test blasting, and the vibration value predicted from this equation was located between the values predicted from the USBM (US Department of Interior, Bureau of Mines), NOF (Nippon Oil & Fats Co., Ltd.), and MCT (Ministry of Construction and Transportation) equations. Additionally, by comparing the measured noise level at full-scale test blasting with the calculated noise levels from several noise prediction equations, it was determined that the noise level predicted by the ONECRC equation had the best agreement with the measured results. However, in cases where blasting includes tunnel excavation, simultaneous measurement of vibration and noise is required to prevent damage to the surrounding facilities.

Waveform Characteristics of Tunnel Blast Waves and a Wave-Blocking Method

“…In blast work, a considerable portion of explosive energy is wasted in the form of undesirable environmental side e ects, such as ground vibrations and air blasts [1]. When blasting work is repeatedly performed in neighboring towns, the ground peak particle velocity and air overpressure (AOp) create signi cant annoyance to personnel and residents [2], and it can even cause the breakage of glass, loss of a decorative layer, and displacement of doors and windows [3,4].…”

“…Strategies could be devised to diminish the signi cance and proportionality of the impact of noise on ESR3, which has been categorized as central to moderate in importance and proportionate to the sensitivity of the receptor. Temporary noise and vibrations during the construction and closure phases may affect sensitive areas(Lee et al 2018), and a receptor's well-being can be in uenced by numerous factors. To mitigate these impacts, effective working practices should be incorporated into noise and vibration management plans until the completion of mine rehabilitation and closure activities(Melodi 2017).…”

“…The British Standards Institution (BSI) TG18-BSI code of practice for noise and vibration speci es that cosmetic impairments should not exceed 15 mm/s at 4 Hz and 20 mm/s at 15 Hz for residential or small commercial buildings. The use of explosives in surface mining can cause ground-borne vibrations(Lee et al 2018). The nearest noise-sensitive receiver, ESR6, was positioned approximately 900 m away from our location.…”
