As the area where stone is used in buildings increases, the amount of stone processing increases, and the amount of dust generated in the processing process is increasing, but interest in this is insignificant. In addition, as a result of investigating the dust generated in the dry process, the proportion of SiO2 is about 70%, so there is a concern about the risk of pneumoconiosis caused by breathing. Therefore, it is judged that it is urgent to collect it at the source to prevent damage to workers and environmental pollution.

Due to the inexperience of stone work and field workmanship, and the preference of simple construction, various problems such as unauthorized cutting of the touch and epoxy bonding are occurring. Therefore, the existing T-type hole construction method was developed to fundamentally control these attempts. As a result of comparison with the control panel method, vibration and noise were reduced by 2dB and 10dB, indicating an excellent effect. Particularly, dust was about 1/102~1/61 in individual values, and the average value was 1/80 (12.5%). The effect of preventing damage and environmental pollution is expected to be great.
