Thanks, I have learned something new, that in the UK coal mining industry, an underground mine is referred to as a pit. I have to admit I know little about coal mines, but after your last message, I did a Google search and the only references I could find to "pit" that are not about "open pit" were UK coal mines - yes, there was one about a Polish coal mine, but it was in English, so who knows? Anyway I´ve been in this business (hard rock mines as opposed to coal) a long time, and when I see "Evaluated pit optimizations, produced pit & dump designs and mine plans...", I am pretty sure this is a mining engineer working on open pit mines.
