Hi everybody:

I hope someone in the group can provide some info that will help
Vali answer his question below.  I have never seen anything that
addresses the question......

We all know about the earth's geodetic MF which no doubt is partially
applicable to the mining environment.  But what are the characteristics
of the wiring that provides lighting, drives the machinery, circulates
the air, etc.,???

I suspect that in the typical mine, the wiring is of poor quality,
probably single phase....  I dare say, this aspect of "on the job"
EMF exposure has simply not been thought about before.....

Good question, Vali ... I hope someone can provide some info.....

Cheerio......
