Let the first lemming bash through the obstacle, one lemming will turn back (ignore it). Turn the first lemming walking ahead into a miner (the same place as in the picture). Two other lemmings will walk back and die. When you're a floor lower, turn the second lemming into a blocker and build over the bubbles with the first one. Bash underneath the obstacles and blow up the blocker.
