These revisions and correctons were <br />made based on information provided by Colowyo, including the two 100 <br />millisecond delays before the A row, and the change in powder density for <br />specific holes. Please review the reconstruction, and provide me with any <br />corrections. In summary, the reconsrtuction indicates that there may have <br />been ninety-six 8-millisecond delays where more than the permitted <br />(scale-distance factor determination) amount of explosives were detonated. A <br />maximum of 7055 pounds within 8-milliseconds were apparently detonated near <br />794 (holes C-51, G-13, and D-42) and 838 (holes C-47, G-9, and D-38) <br />milliseconds into the blast. <br />«blast analysis time brackets revised and corrected.xls» «blast <br />analysis corrected & revised.xls» <br />
