[QUOTE="user 4386, post: 578614, member: 4386"] Even tunnels are risky for the inexperienced - people have died in them on a number of occasions (eg even gas can collect in a slight incline. When miners worked in them they used to bar down the loose rock every day before others entered - many tunnels have not been barred down in a hundred years and it requires expertise. Usually far less productive than the old dumps outside them - would take time to explain why but for very good reason (I am a mine geologist). [/QUOTE]
