수공에서 자립형 수중용 에어튜브 발파공법에 관한 연구 = A Study on Self Supporting Air Tube Blasting Method in Water Hole

다국어 초록 (Multilingual Abstract)

A study about economical blasting methods which can improve fragmentation and save explosive in blasting is in progress. One of the blasting methods is an air decking method making air layers in boreholes. However, it is difficult to apply this method to the boreholes filled with water. In this study, an underwater Air Tube was manufactured and tried to place it at a certain location in a water filled borehole. It was found that the application of underwater air tube in wet boreholes could improve the fragmentation and save 10~15% of the explosives.
