Research aims to analyze the problems of the mining industry at the initial stage of the current “fourth industrial revolution”. It is noted that the total digitalization and robotization of technological processes will not save the industry from excessive energy and water consumption until the basic problems of the irrational use of these resources are resolved. Taking into account that the change of generations of technology is accompanied by a paradigm shift, the concept of a new paradigm is presented.
The methodology of the analysis is determined by the content of the paradigm of technology for the extraction and processing of mineral raw materials. An “ideal final result” has been formulated, which meets the principles: do not extract, crush or enrich anything superfluous. In this paper, the tasks are set in terms of the development of new technology and equipment to achieve qualitatively different indicators of ore preparation.
The results of the new paradigm analysis are based on selectivity principles, according to which intermediate and final products of ore preparation are supposed to be formed as a result of successive cycles of transformation of division structural elements into disclosure structural elements. Since, with ordinary grinding, the newly formed surface is much (tens of times) higher than the surface of the accretion, the reduction in the volume of the material during selective destruction will make it possible to reduce the energy consumption per opening by several times. The scope of the concept under consideration is the entire mining and processing industry, since practically all large subsoil users use the same ore preparation cycle: explosive blasting–crushing–opening– enrichment.

Key words: ore preparation; change of generations of technologies; selective destruction; resource saving.
