He was fine after the building he was in exploded while fighting Varnae, he was fine after he blew up the nuclear facility in Vanguard,he was fine when Deadpool hit him with the bomb that blew up half the train car, and he was fine with the Hellicarrier he was in crashed to the ground and exploded. Chalk it up to durability or healing, but he's taken explosions before and been fine.
Yeah, Blade has definitely survived worse explosions than this. Still plenty impressive though. And Blade can use all the good feats he can get.
