When I was about 3 years old I remember watching a very strange film. There was this peculiar "red mine" (as I call it), with a kind of post-apocalyptic futuristic vibe. I also remember that in this "mine" (I actually don't remember for what purpose the supposed "mine" was actually used in the film) there were prisoners, clothed a bit like desert maniacs from Mad Max, or at least it seemed that they were there for some involuntary work. The last thing I can remember are some large wood pillars on which different kinds of linen, they closely resembled nomad tents. I very faintly remember very tall machines, the shape of which I forgot. The film is from the time period 1980—2004.
And that's about it. Please, if you know any film that my description closely resembles, let me know about it. All answers are greatly appreciated.
P.S. The described is only a portion of the film (about 20 minutes I think), so keep an open mind about it. Furthermore, it is possible that the described scene is from a film I do know but just don't remember this particular portion.
