I'm a retired underground miner / Top Millwright and like Richard, I have used thousands of blasting caps. If your caps are Electric Caps (wires attached to each cap) the wires need to be shorted either by having the bare ends twisted together, a Fahnstock Clip on the ends, or a small metal foil wrapping. Without being shorted, they could be set off by static electricity. If they are Fuse Caps (open on one end), there are two variations - the newer Aluminum cased caps, and the old style Copper cased caps. The Aluminum caps are a little bit safer as the internal composition was changed so that they are not as sensitive to shock as the old Copper caps. The old Copper caps had a Mercury Fulminate / Lead Azide composition and are very shock sensitive. Also, over time the Mercury Fulminate will react chemically with the Copper and form EXTREMELY SENSITIVE metallic salts of Fulminate.
As Richard stated, NOTIFY YOUR LOCAL AUTHORITIES and let them deal with it. Most large Law Enforcement agencies have a Bomb Squad that are specially trained to handle explosives.

I have picked up and attempted to read every auto and farm electrics book with no improvement in the situation. They all seem to start with a chapter entitled "Theory of Electricity". After a few paragraphs I usually close the book and go back to banging out dents. A good friend and I were recently discussing our tractor electrical systems when he stated "I figure it all comes back to applying Ohms Law". At this point
