The higher the blast resistance, the stronger the explosions it can withstand. Say a creeper trys to destroy a cobblestone block from 4 blocks away, the cobblestone will not be destroyed as the blast wasn't strong enough. If it was 2-3 blocks away, however, the cobblestone might break. Or say you use a nuke against reinforced stone, you may need a couple of layers to withstand the massive blast, even though reinforced stone has a very high blast resistance.
