Explosions take the path of least resistance. They shoot in sequence to
provide that path. First sequence starts it. Second will blast the rock
to where the first was, and so on, and so on. It's more controlled and
you use less powder.

I think you misunderstand. These were half ton charges many feet
apart. Turned hundreds of acres into rubble. I don't know but I will
bet the endloaders and trucks are really big. The ships certainly are,
thousand footers that are too big to get out of the Lakes.
