Tug Fork River Big Bend Cutoff Blast Monitoring Study.

Abstract

This report documents the results of a blast vibriation monitoring program conducted in the vicinity of the proposed Tug Fork River Big Bend Cutoff. Explosive and traffic (railroad and highway) induced vibration data were measured at selected sites in the vicinity of the proposed excavation. Analysis of these data shows that the railroad induced maximum peak particle velocities are one-tenth or less (= or < 0.2 in./sec) than the damage threshold for structures ( 2 in./sec) and one-fortieth or less than the damage threshold for unlined tunnels (8in./sec). Dominant frequencies of the recorded data are in the range 30 to 50 hz. This frequency range dictates a minimum delay time of 30 msec.
