Abstract: The ore bodies of the Oleniy Ruchey deposit have a complex morphological structure, chaotic stretching over the entire area of the quarry excavation and other features, which imposes restrictions related to the opening, preparation and development of sub-quarry and instrument reserves. In this regard, the features of the occurrence of ore bodies of the sub-quarry reserves of the Oleniy Ruchey deposit are considered, which provide a comparison of technological schemes of open and underground mining operations. To visualize the ore bodies, the spatial location of the ore bodies of the Oleniy Ruchey deposit is given. For the excavation of the sub-quarry reserves of the deposit, the technology of a sub-storey collapse with a face release of ore and a variant of the system with an open worked-out space is proposed. The design parameters of geotechnologies and the volumes of mining and capital and preparatory cutting works are given. The procedure for working out temporary and inter-chamber targets is proposed. A flanking scheme for opening and preparing the instrument and sub-barrier reserves of the upper tier of the field has been developed. The performed technical and economic calculations confirm the economic feasibility of mining reserves by underground method.
