put one bomb near the block, the second one near the flag and than after blowing up the first bomb put one by the left side of second one and run in the tunel. than by blowing up your secong bomb you push the third one to the block and can blow it up

The way I did it was place the first bomb next to the wall and the second on top of the first bomb. Then back away from the bombs as not to get knocked back and explode the first one. As the second bomb gets launched into the air, go in the tunnel. Then when you want to get out, explode the second bomb, which now should be where the first bomb was.
