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 controlled explosions. Here is Mickey and some of his team.

Mickey in different configurations

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

and here is Brett Rogers - cutting PVC sections

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.

The result (before)


and after

Working from a barge - with Ken using the rod to tamp the material into place

and the result - detonation at the base

which propagates to the cap
