#3 #4호기 보령화력발전소 기초공사 정밀발파공법
Cautious Blasting Works on the Po-Ryong Power Plant #3 #4 Foundation
초록
On the foundation work of Po-Ryong power plant #3 & #4. It was 30meters away from the running states of #1 & #2 plant site. In order to protect the #1 & #2 power plant facilities & factory structure. Allowable vibration was required below 0.07 gal. Therefore, it had to set up the anti-vibration trench to reduce the vibration reference and secondary. I applied the low gravity and low velocity explosives with M/S delay caps by cautious blasting pattern.
