don't go down t' mine, Da', there's plenty of coal in't' bath...
the thing is, not to start out by believing the roof won't fall in and go on like that. There are parts of any old mine which AREN'T safe, and you need to learn from the beginning to recognise them.
'best practices' such as, for example, walking out over rotten false floors by only treading on the rails... :blink:
that, of course, is where the experience comes in.....
