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.

The research on improvement of false alarm from the automatic fire detection system has been continually achieved in the meantime. But the research for the code-transmitter as one of component devices of the automatic fire detection system. In order to improve difficulty of the code-transmitter check-up, introduction for the address type-code-transmitter and the automatic recovery system for check up of the code-transmitter was proposed. In order to prevent against occurrence of noise and signal attenuation, introduction of the optical fiber cables that noise and signal attenuation do not occur and introduction for an optical communication relay that can apply to was proposed respectively.
