Optimization solution substantiation for resource-saving maintenance of workings

Purpose. Substantiate the expediency of optimizing decision-making in resource-saving maintenance mine workings. Methods. The concept ensuring conditions for repeated use working is based on modern methods managing rock pressure manifestations, conducting multifactorial computational experiments, experimental verification principles’ implementation during effective resources full-scale conditions. Findings. directions improving fastening and protection structures, which ensure stability reused workings, have been determined. In this case, most lightweight structure proposed, functions are transferred to collapsed compacted rocks uncontrolled collapse zone. Originality. basic taking into account technologies, has formulated implemented. stress-strain state “mass – support elements” system studied, its rational parameters optimized. An example an optimization solution stated methodology presented. Practical implications. schemes developed calculating loading structures workings with a geomechanical substantiation adopted provisions assumptions, basis issuing recommendations stability.
