The concept of unmanned mine production based on the use of non-traditional physical effects and phenomena, as well as a possible method of its implementation with the help of a multi-agent robotic complex, is presented. The complex includes a rock-milling and ore-preparing mining combine, auxiliary stand-alone stationary and mobile robotic systems and pipeline pneumatic conveying. The design of the com- bine used three inventions (RF patents No. 2136397, No. 2234603 and No. 2404862). Extraction of the rock takes place in the form of crushing of the surface layer of the rock monolith and the surfaces of the combs of the working organ of the combine at high frequency impacts of the strikers along the surface of the ore body. The combs are made from blocks of rock and create the effect of "threshold destruction" of the rock. The effect is to limit the value of deformation stresses in the polycrystalline structure of the near-surface layers of the material within the threshold of the strength of intergranular bonds. Because of this, with mutual impacts of the surfaces of the rock monolith and striker in the near-surface layers of solid rock, the surface microcracks grow along the intercrystalline boundaries. As a result of multiple repetition of impact impacts, fatigue distur- bances accumulate in the structure of the subsurface layers of the rock, resulting in the separation from the monolith of the ore that has been mined with a high degree of selectivity. The automation of the proposed combine provides op- timal conditions for the accumulation of fatigue structural defects. The design productivity of the combine is not inferior to the daily productivity of three-brigade mining using drilling and blasting operations with the laying of providing penetrations and the use of mining equipment 52 items. Crushed ore is collected by the suction pneumatic system of the combine and fed to the airgravity separator of the mixture materials, from which the concentrate is transported directly to the surface by the pipeline pneumotransport to the concentrat- ing factory, and the empty rock is fed to autonomous mobile shotcrete complexes for the preparation of fast-setting embedded material and the laying of empty excavations. In the concepts of aggregate designs, in the solutions of algorithmic and kinematic problems of aggregate functioning, navigation, positioning and interaction of autonomous aggre-gates of the multiagent complex, the author has experience in developing and creating systems for supporting intelligent decision making and creating multi-agent robot systems. The application of the new technology will lead to a significant reduction in energy consumption of ore production, a multiple reduction in the amount of material extracted from the mine, with a corresponding reduction in environmental pressure on the environment.
