Abstract The authors discuss applicability of manmade bottoms (MB) in extraction panels, with fast reinforced-concrete support platform at the ore drawing and haulage level in stoping with caving. The structural components of the proposed-design MB capable to stand high overburden pressure in mining of thick ore bodies using the systems of stoping with caving in the conditions of unstable ore and enclosing rocks, including deep-level mining.
