Information × Registration Number 0217U000329, 0115U002104 , R & D reports Title Research of processes of the многостадийного forming and development in time and space of explosive seismic impulses with the use of short slow explosing on mountain business. popup.stage_title Head Бoiko Victor Viktorovich, Registration Date 26-01-2017 Organization The Institute of Hydromechanics of the National Academy of Sciences of Ukraine popup.description2 By a research object - there are processes that arise up from the explosion of charges of explosives of different form of book-mark and symmetry and that influence on a pedigree array. An aim of researches is research of influence of explosions of charges of explosives of different form of book-mark and symmetry on a pedigree array for determination of authenticity of application of law of geometrical similarity of Newton during realization of calculations of seismic safety of quarry explosions and comparing to other researches.Methods of researches: analysis of the known scientific results of existent norms of seismic safety, in relation to the methods of prognosis seismically safe realization of blasting works and method of his generalization; determination of terms of origin and distribution of superficial wave, including depthfirst, establishments of conformities to law of development of the processes caused by the action of different types of waves from the explosions of single and shortly slow explosions of the system of cylindrical charges of explosives taking into account the law of geometrical similarity of Newton array of breeds; graphicly analytical method; methods of mathematical statistics. Research of influence of explosions of charges of explosives of different form of book-mark and symmetry is investigational on a pedigree array taking into account the law of geometrical similarity of estimation of array on his resilient descriptions, relative depth of book-mark of charge and power descriptions of explosives and condition of origin and distribution of superficial wave, including depthfirst array of breeds. Researches of seismic effect of explosion of the dispersed charge are improve the methods of determination of unconcern of seismic explosive waves for seismic firmness of building and building. The results of statistical, graphic analyses of methods of treatment and experimental materials showed on the seismic effect of instantaneous and slow explosion of charges of explosives, what after the degree of observance of law of similarity, and on exactness of calculation of parameters of seismic explosive waves, formula, based on the law of geometrical similarity of Newton gives the best results at determination of level of seismic danger for providing of seismic firmness of building and building, as compared to researches in the countries of far abroad. On the basis of researches of influence of depth of book-mark of charge on intensity of a shake process, relatively different types of waves of P, S and R, further development of scientific presentations, that allow to get explanation in that the periods of vibrations of waves of S and R have the same dependence on distance and type of breeds, is got, and in the waves of P there are differences at the decision of direct tasks after the formula based on the law of geometrical similarity of Newton. Summarizing dependence of speed of displacement of breed is got on the parameters of explosion of the dispersed charge and distance from the central point of hearth of explosion to the looked after point at the level of engineering formula. The results of scientifically experience work will be drawn on open mountain extractive enterprises. Product Description popup.authors А.І. Лучко Д.В.Хлевнюк Кузьменко А.О.
