SCP Foundation

So my idea is a Mine, maybe an iron mine somewhere in northern England (I'm just throwing this idea around). I imagine the mine was discovered by the foundation in around 2002 (maybe earlier) anyone who has entered the mine and has not left within 24 hours will become trapped in a sort of loop, they will repeat the exact same actions they did from when they entered, they will keep repeating with no end.

Some workers who were caught in the anomaly are at the top and mention many other workers that are in the mine, however exploring that deep is impossible without being caught in the loop.

People trapped are still subject to decay as made evident from workers close to the surface who's flesh is rotting.

quite vague i know but if a bit more was added to this do you think it would be any good?

Thanks

I think this definitely has some potential, maybe as some kind of endless rescue operation? A timeloop where miners got trapped and the rescue operation gets continually reset at a certain depth. That gives some instant conflict in your narrative and gives you a lot of room to explore how the logistics of this type of rescue operation would go, and whether or not people even want to be rescued if they know more people are going to be sucked in.
