This mod (first version) only adds 2 config options, and that's it. It adds a list of blocks to change the explosive resistance of, and a number to set the explosive resistance to. The default for the list of blocks are all the vanilla minecraft ores, and the default explosive resistance is set to 4000.0, which is double what obsidian has.
The second version adds 1 config option, a list of block names, followed by a number to which to set the explosive resistance of the block, in a manner as the following: "minecraft:iron_ore-4000.0"
"minecraft:iron_ore" is the block and "4000.0" is the resistance to set it to, seperated by a "-".
