Geologic Factors Affecting Vibration from Surface Mine Blasting.

PB86175858

Publication Date	1985
Personal Author	Reil, J. W.; Anderson, D. A.; Ritter, A. P.; Clark, D. A.; Winzer, S. R.
Page Count	211
Abstract	A test series of small, precisely controlled and thoroughly monitored production blasts was conducted at two quarries. In each series, all variables except delay were kept constant, as much as practically possible. The first aim of the study was to determine the effect of local geology on ground vibration. The second aim was to test several hypotheses relating the effect of millisecond delay intervals to fragmentation and ground vibration.
