On the one hand, I wouldn't bother with it. Mining has never seemed hard to skill up, and wow, a chunk of stamina. No other stats/ Doesn't seem worth it to me.
On the other hand, leveling faster might make it more difficult to keep your skill maxed if you're focusing on leveling and not going out of your way to mine as you level.
Really comes down to though whether or not you feel it is worth the time/mats to make. Each person will think differently about that (I never used the +enchants to gathering skills either).
