Abstract

Maximizing the efficiency of blasting operations is crucial for reducing project costs, shortening timelines, and minimizing environmental impacts-key factors for the success of large-scale marine reclamation projects. This study explores the application of pocket-charging methods, developed from mining principles, to enhance rock fragmentation efficiency in large-scale blasts. The aim is to optimize the material production process for marine reclamation construction. The pocket-charging technique efficiently disperses blasting energy, increasing the extent of rock fragmentation and thereby improving overall blasting performance. Even with minimal explosive quantities, optimal results and cost-efficient, expedited construction can be achieved. This research validates the effectiveness of pocket-charge blasting through blast simulation programs and outlines suitable blasting designs and strategies.

발파공사의 효율성을 극대화하는 것은 비용 절감, 시간 단축, 환경 영향 최소화와 직결되어 프로젝트 성공의 핵심요소이다. 이 연구는 대규모 채광발파의 마이닝 개념을 바탕으로 고안된 포켓차지 공법을 적용하여 암반 파쇄 효율을 극대화하고자 하며, 이는 해양매립 부지조성 공사의 매립 재료 생산과정의 효율성을 높이는 것을 최종목표로 한다. 포켓차지 공법은 발파에너지를 효율적으로 분산시켜 암반 손상 범위를 넓혀 전체 발파효율을 향상시킬 수 있으며, 소량의 폭약만으로도 최적의 발파 결과와 경제적인 급속 시공이 가능하다. 본 연구에서는 발파 동해석 프로그램을 통해 포켓차지 발파의 효과를 검증하고, 적정 발파설계 및 기술적 방안을 제시하였다.
