Keywords: ROCK ROCKS, EXPLOSIVE SUBSTANCE, EXPLOSIVE IMPEDANCE, EXPLOSIVE WAVES, ACOUSTIC JOURNALITY OF ROCKS, INTERFERHER. The object of study - the process of destruction of rocks by explosion. Purpose - Development of theoretical and methodological provisions and practical recommendations for reducing the energy loss of the explosion and the use of excess energy of explosive waves for additional destruction of rocks. Research methods - physical-mathematical and analytical methods. Results and their novelty - the novelty of the work is protected by the patent of Ukraine for № 136031 from 10.01.2020. According to the materials of the GDR, an article was published in 2020 in the collection of scientific articles: "Method of destruction of rocks by explosion". The main design, technological and technical and operational characteristics are set out in the report Implementation information - the method of destruction of rocks and semi-rocks by explosion is planned to be implemented in the quarries of Metinvestholding LLC. Interrelationships in other work: improving the load on the rocks and reducing the cost of drilling. Recommendations for use: it is planned to use in the destruction of rocks Scope: destruction of rocks by explosion in opencast mining. Economic and socio-economic efficiency: reducing the cost of drilling and blasting. Significance of work: work is useful and has practical value. Conclusions, proposals for the development of the object of study and the feasibility of continuing research: to recommend the results of research work to be used in the development of parameters of passports of drilling and blasting operations at the quarries of Metinvestholding LLC. Terms of receipt of the report: under the contract. Product Description popup.authors Krupko Ihor V. Pavlov Yevgen Ye. Fesenko Eduard V. popup.nrat_date 2021-07-20 Close
