In the blast work inevitably exists a vacant space between drilling hole wall and explosive. So it cause an blast inefficiency called on a decoupling effect. In this study, For enhancing the detonation efficiency and reducing the environmental problem(vibration, noise, etc.), water is used to fill the vacant space. Water filling has many advantages such as efficiency, low price and workability. In the comparison analysis the field test is carried out. It result on an aspect of the effectiveness and safety. The result measured in the field is as follows; First, the water tube blast reduces the vibration by 16.5% and lessen the noise by 1% comparing to general blast. Secondly, water tube blast makes a separation distance shortened by maximum 15m. Thirdly, in the case that the same quantities of explosive are used, the amount of crushing per hole increased by about 12.8% in water blast method. The quantity of the explosive is reduced by about 11.4% comparing with general blast.
