On the image below is a mining machine produced by the Kopeysk Machine-Building Plant. I'm not sure how to call it in English. The Russian name is "prokhodchesko-ochistnoy kombain".
Multitran offers the translation "heading and winning machine", but I'm not sure: when I enter this term in Google, it finds predominantly Russian-based websites.
The machine is used for underground mining. This particular model is mentioned in a text I'm translating about an overpricing row between the Russian potash producer Uralkali and the machine-building plant.
I found the company's description of the machine:
The «Ural-20R-00» heading-and-winning machine is designed for longwall operation in сhambers and driving of oval-arch shaped workings in potash ore seams with thickness of 3.0-3.7 m at dip angles of ± 12° and rock resistance to cutting of up to Аp=450 H/mm.
