To make an automated mine or not? {POLL}

Hey guys. Im trying to get a server up, and I can't decide what to do. Should I make an automatic mine using MineResetLite plugin, or should I just let the players explore the world and mine wherever they want? The reason I don't want them doing the latter is because I don't want huge ass holes and tunnels all over the world. However, putting in the automatic mine restricts mining by a lot. It can make mining not as fun, unbalanced if there aren't/are too many ores. Also, what happens if I put a worldborder around my world, and most of the ores are mined in this area? Then what do players do? Please help!
