Blast Resistance Checks and Block Data

This is my second time posting this because I put it in the wrong section the first time.

I'm making a mod where I'm creating a new explosive that has its own explosion pattern. I've got the explosion working, but I am unable to check for the blast resistance of the blocks being destroyed to see if there's enough force for the explosion to continue. It would be great if there was some robust system allowing users to get block data like blast resistance, flammability, and whether a block is waterlogged. Alternatively, a block like "get hardness of a block" for blast resistance would be good.
