Application Research of Controlling Vibration from Chamber Blasting in the Complicated Environment
According to the chamber blasting practice for fidd leveling of Yichang railway south station, this paper sums up the vibration controlling experiences from the chamber blasting practice with extended charges near inhabited area. Based upon analyzing of the test data, reasonable firing time intervals of concentrated charges and consecutive firing circuit were proposed and influence of topographical and geological conditions to the vibration attenuation was analyzed. Meanwhile, the different anti-vibration index was introduced according to the quality and use of houses. Result shows that this chamber blasting practice is successful. No damages occurred to the neighboring houses from the blasting vibration. The design requirement, quick excavation with large-scale blasting in complicated environment, is fairly achieved.
