1) Drill a 1.5'' diameter hole in the stump, about 3-4 inches deep
2) Fill it with gunpowder

Aside from the legal problems, admit that you have no idea how big or deep
this hole should be, and how much powder to charge in. Guessing will not
work. Some things can be learned on-the-job, but blasting?

There are good reasons that stumps are no longer removed by blasting, even
by those who might know how.
