BTW. That stuff is known as ditching fertilizer around the farm parts of Wisconsin.
In combat engineering and mining, AN mixtures are used as festering charges to damage/ destroy roads rails bridge abutment etc and other tasks requiring a lower speed heaving effect.
Quarrying relies in modernized versions.
It is very safe until an initiation system is added.
As a cbt engr, I jumped with charges or caps never both.
Always a very moving right when a pattern of 40 lb charges are detonated on a roadway to deny enemy use, first, shaped charges blow holes, then one, two or three 40 lb charges are placed in rows to heave the material towards the enemy’s approach, and fired. Watching some 100 cu yds of pavement, base and earth move like a cup of flour being heaped is cool. Biggest I planned and shot was some 1200 lbs in one target.
SIL is a master blaster for a large quarry operation in SA TX. He routinely shoot 2 t of mix in 100 holes and busts 100t of rock. All with no above ground effects. They get in trouble when it goes aerial.
