As long as you average 2 pieces per bomb and keep your evo running 24/7, it is possible. I have one evo chamber and the only mining dragon I didn't manage to get was Sulfur on it's 1st release. That one was 350 pieces (got it on the 2nd release because I had over 300 pieces sitting in storage from the 1st run).
