As a native English speaker I find this text VERY difficult to read without analyzing it very carefully. I would say you are correct in all 3. When you mine something you retrieve something of value. I don't know what "the death drive" is or "unpleasurable pleasure" is. "unpleasurable pleasure" is an oxymoron. Oxymorons are purposely confusing. It makes me think the author of this text wants the reader to know that the author is a profound person.

My interpretation of the latest of your questions on horrific texts. 1. Does "works that mine the structural effects" mean "works that consider and explore the structural effects"? "mine" usually means to discover or recover something form somewhere or something. Mine gold from the ground. So, close, but more "get material or ideas or creativity, maybe, from the structural effects" 2. Does "which feature repetition and blockages to narrative" mean "which feature a. repetition and b. narrativelessness"? I don't think so. feature, repetition, yes. Also blockages, stoppages, things which stop the narrative. Stressing stopping rather than the lack of. 3. Does "Narrative continuity and resolution" mean "Narrative continuity and coherence" More like Narrative continuity and conclusion, fulfillment. While "resolution" can mean fine structure, detail, here I think it has the more common meaning of being resolved, completed, finished.
