Well, I "studied" it and found out that it was a restaurant until a couple of months ago. There is nothing to indicate any kind of experience in coal business.

And no, it's not a common practice to get sued. I would not trust a contract with some shady folks who have a habit of being sued for a breach of contract.

I have a feeling that you either think everyone here is stupid, or you're really really dumb yourself. Perhaps you're some fiverr guy who got hired by those crooks in Kuzbass to do the posting in English and now you're got yourself into trouble. You don't know shit about the "business" you're supposed to represent, so you're contradicting yourself. You don't know English and you can't even spell Russian properly so translation software doesn't work well with this garbage you're posting.
