Comparative analysis of designed and consumed materials during shotcrete bulkhead construction

When applying the cut and fill mining method, the empty spaces after excavation of the ore body are filled with mine tailings from the preparatory workshops or flotation tailings enriched with a binding agent, brought from the surface. When using flotation tailings as a filling material, it is necessary to partition (limit) a certain excavated area with a bulkhead before filling it. In this paper, the stages of shotcrete bulkhead construction are shown, a comparative analysis of the projected and consumed materials during their construction is also made.
