^ It is possible, with perfect bomber timing, to save the athlete on the left side, although it's certainly not easy.
I have one other suggestion in the spoiler below. It's a little tricky to pull off, but if successful, it makes things a lot easier on the right side:
On the left side, use 3-4 bombers instead of the second miner, being careful so that nobody goes left after breaking through. If successful, then you can use the miner on the right side to drop down one level and unite the two groups in one fell swoop.
