| Popis: | Research objective is to substantiate the relevance of mining transition to eco-friendly technologies of subsurface use. Methods of research include analyzing theory and practice of environmental technologies application and carrying out a multifactor experiment. Results. An efficiency criterion for mineral resources extraction technologies is proposed that involves reducing the effect made by the by-products of mining and processing enterprises on the state of the environment. The problem is considered of minimizing the environmental damage from storing silt coal in dumps and storages by utilizing their components. The mechanism of environmental pollution has been formulated. Aspects of metal recovery from beneficiation tailings in a disintegrator mill are investigated. A reduced threat to living matter is predicted by implementing the concept of radical waste-free processing of substandard mineral raw materials. The need to improve the processes of crushing, fine grinding, and classification of minerals in mills to reduce the waste of coal production, harmful to the environment, is noted. Conclusions and scope of the results. Deteriorated conditions of mineral deposits development raise the risk of man-made impact on the environment in coal-mining regions. The global human population grows resulting in increased resources production to respond to resource needs. The growing threat to living matter can be reduced by radical measures, the non-waste processing of substandard mineral raw materials being the priority. The research results can be helpful in the development of deposits of solid metal-containing technologically exposed ores |
