Ds R1 = D/(Thf) D = Shot/instrument distance.
T = Total lbs. explosives.
M = Maximum lbs. explosives per delay period.
1/2
Ds X2 = D/W D = Shot/instrument distance.
W = Maximum lbs. explosives per delay period.
Nht means instrument not equipped to measure airblast.
NR means airblast not recorded due to low level or other condition.
* Ground vibration exceeded range capability of instrument. PPV determined by
projection of tangents. ite believe it represents the maximum possible at this
point.
': We have extimated the maximum charge weight per delay based on the time duration of
the shot firing sequence. Ds calculations based on.thi_s larger charge are shown in
parentheses. ,'~~
