You don’t want to blow up asteroids. Aside from the risk of reformation, there’s no guarantee that it will even break up solely into pieces small enough to not cause serious damage because it is hard to tell what asteroids are actually made of. Hence, the DART project, which tries to move the whole asteroid.

You don’t try to blow it up. You use the force of the explosion to nudge it off course just like the DART program did. It’s on NASA’s interplanetary defense website.
