this has been suggested before never went any where +1

 

I don't think /kit tnt is necessary, knowing that players with high excavation skills can get sulfur fairly easily, but I think tnt in the mining world would be cool, new traps like landmines could be added. The same rules with the Nether should apply (no blowing up the spawn/area immediately around the spawn) as well should this be added.

 

Complete support, TNT in mining world should be allowed, but I'm not quite happy with how the moment you're outside of the spawn area, everywhere has been dug up or changed. TNT could encourage this, but I'm pretty sure it won't affect the spawn area, seeing as the explosion of creepers do not either. I don't quite see much point in the "/kit tnt" ability the suggestion's given, though, as, as previously stated, it's not hard to create TNT.

Complete agreement with above.
