hahahahaha. NO. Both games use a graphical representation called Voxel. The "mining", exploring (sandbox), and that kind of "behavior" is called gameplay. The visual/graphical representation + gameplay are not under copyright.
In videogames industry: the assets (soundtrack/voices, skins, logos, art, typography, etc.); script (story, character dialogues, names, etc.); and, obviously, the source code (it doesn't matter if the game was build from scratch or with a game engine) are the only sections with copyright.
