I was heading up a vertical tunnel at the time, so I tried to move fast to avoid an ambush, then I noticed the dungeon at the top
when i encounter a spawner, 30 out of 31 cases i have battled my way through tunnels and mining shafts first, slowing me down considerably. there's no need to fix things based upon a lucky occurrence.
BTW usually makes things harder. If you get a lucky incident, deeply cherish that and think of it when a Beast devours your soul.
