Hate to say it but not a chance theyre alive, not even a slim one
Its a sad day for miners all around the world and a scary one at that. I remember the mining tragedy in Tasmania a few years ago, they survived but still. The mine was also closed down if I remember correctly and hundereds people were without a job, hence the tragedy, it doesnt only affect the immidiate situation but the aftermath for the community (with or without losses) is huge
I hope they died a peacefull death
