Outline of Final Research Achievements

Rock blasting is the rock excavation and fragmentation technique widely adopted in the various fields of the mining and civil engineering because of its economic efficiency. On the other hand, the blasting operation may have an impact on the surrounding environment, such as ground vibration, flyrock, noise, etc. in case the blasting standard is not appropriate. The new guidelines have to be developed in terms of safe and economical in order to apply blasting technology more effective and widely. From these points of view, at first, the mechanism of rock fragmentation by blasting were discussed and made clear by means of small scale blasting tests and numerical simulation. Then, the effects of blasting standard and rock mass conditions on the rock fragmentation and flight characteristics of fragmented rocks based on a series of field blasting tests. Finally, the new guide lines for blasting design were proposed.

Academic Significance and Societal Importance of the Research Achievements

本研究で提案した「環境低負荷型コンパクトブラスティングシステム」を活用することで、これまで発破作業の適用が困難とされていた地山や住宅近隣地域においても、発破工法の適用が可能となり、作業効率の向上だけでなく重機の稼動に伴うCO2排出の削減も可能となる。さらに、構造物の解体や人命救出のためのアクセス通路の構築等、救助作業にも適用が可能で、人命救助・災害・復旧への適用も期待できる。以上のことから、本システムは、鉱山および土木における発破工法の安全・効率化から、災害時の人命救助および災害復旧に至るまで、発破工法の適用領域の拡大を可能とするシステムとして、日本が世界に貢献できる技術の一つになると考える。
