January 22, 2006: Mickey Rogers and his ABS team
I am not sure how I first met Mickey but he has been my professor of

Some more of Mickey's team: Mickey Rogers, Ken Tully, Dave Holland and

Something about preparations: Drilling
Now for the loading process - Ken inserts two sticks of dynamite with
an embedded detonator and Mickey gently tamps it into place.
Another episode: Phillip loads a stemming bag while Ken tamps it into place.
After loading is completed - here is what the loaded columns look like.
The red and yellow strings comprise the fusing -
to the left and to the right are connected
with yellow lines (9 msec delay). The red lines have 25 msec delay.
