Relevance and Objective of the Study. Due to depleting mineral resources, industrial companies are involved in mining deposits or their individual sections with increasingly complex mining and technical conditions. Complex structure deposits of valuable mineral raw materials should be mined taking into account the resource-saving principles and ensuring the selection and downstream blending of technological types of ores to reduce a non-uniform composition of the ore mass entering the beneficiation stage. The quality of the mined ore mass influences the efficiency of all the downstream processes; therefore, the mining technology and its parameters are to be linked to the mineralization structure of the mining block and the ore value, complying with the requirements for the beneficiation technology. Objective. To develop a technology for the mining of complex structure deposits ensuring a selective preparation for the excavation and the actual excavation of various ore grades, while ensuring a high-quality blending of the low-grade and run-of-mine ore masses to prepare ore mass parameters optimal for subsequent processing and to ensure maximum metal yield in the beneficiation process. Results. The paper proposes the technology of the combined preparation for the selective extraction of ores from complex structure deposits, using a flexible combination of mechanical, explosive and special methods of rock disintegration. The technology consists in the allocation and outlining of zones of ores of different grades based on the data of the accompanying operational exploration and preliminary mechanical extraction of the highest-grade (lump) ores using drilling. Then the high-grade ore zones are drilled with boreholes or small-diameter wells for subsequent blasting and producing small-size ore mass, and the remaining part of the extraction block, composed of ordinary and low-grade ores, as well as barren rock, is disintegrated by explosive preparation with the conventional parameters of blast holes and their grid. To carry out the subsequent selective extraction of ores of various grades, it is proposed to use single-bucket loaders and wheel scrapers with advanced working equipment. Practical Relevance. The combination of the mechanical excavation and differentiated explosive preparation of ores contributes to a subsequent significant impact on the extraction performance during mining and processing. The proposed mining technology and an improved scheme for the subsequent separate processing of lump and blended ores, as well as industrial products from previous beneficiation processes, contribute to a high total metal extraction from ores of a complex structure mining block.
