Abstract

We developed empirical blast-vibration prediction equations using 2,506 field measurements collected from 46 blasting sites in Korea. The scaled distance (SD) was calculated using charge weight (W), distance (D), and peak particle velocity (PPV), and a log–log regression yielded vibration constants (K) and attenuation exponents (n). The representative equation for the entire dataset yielded a K value of 60.51 (50% reliability) and n value of 1.499 with an R2 value of 0.735. There were distinct differences between equations for specific rock types (igneous: K = 82.07, n = 1.546; metamorphic: K = 48.82, n = 1.487; sedimentary: K = 54.82, n = 1.356), confirming the influence of geological characteristics on vibration attenuation. Compared with the conservative government guideline (K = 160, 200, n = 1.6), the proposed equations provide more realistic predictions for practical blasting design and vibration management.

본 연구는 국내 46개 발파 현장에서 수집된 2,506개의 발파 계측 데이터를 활용하여 암종별 발파 진동 예측식을 개발하였다. 지발당 장약량(W), 이격거리(D), 최대 입자 속도(PPV)를 바탕으로 자승근 환산거리(SD)를 산정하고, 로그–로그 회귀 분석을 통해 발파진동상수(K)와 감쇠지수(n)를 도출하였다. 분석 결과, 전체 데이터에 대한 대표 예측식은 K = 60.51 (50% 신뢰도), n = 1.499, R2 = 0.735로 나타났으며, 암종별로 화성암(K = 82.07, n = 1.546), 변성암(K = 48.82, n = 1.487), 퇴적암(K = 54.82, n = 1.356) 등 뚜렷한 차이를 보였다. 이는 암종의 지질학적 특성이 진동 감쇠에 중요한 영향을 미침을 확인시켜 준다. 본 연구에서 제시한 암종별 경험식은 기존 권고식(K = 160, 200, n = 1.6)의 보수성을 보완하며, 보다 현실적이고 합리적인 발파 설계 기준 마련에 기여할 수 있다.
