Information × Registration Number 0216U003620, 0115U002104 , R & D reports Title Research of processes of the rich phasic forming and development in time and space of explosive seismic impulses with the use of short slow explosing is on mountain business. popup.stage_title Head 1.Boiko Victor Viktorovich, Registration Date 02-02-2016 Organization The Institute of Hydromechanics of the National Academy of Sciences of Ukraine popup.description2 The object of the research: a patent and literature mining with the use of blasting, which would be consistent with the characteristics and structural-geological conditions of rock masses that are being undermined. Mathematical modeling of amplitude-frequency spectra of the seismic wavelet from the action of the explosion of single and group of charges of cylindrical symmetry, which instantly undermined or briefly delayed in the mountain range and the development of algorithms and software for numerical calculations.Research objective:evaluation of the influence of instantaneous and briefly delayed the blasting on the formation and distribution of amplitude-frequency spectrum into a complex structure of the rocks based on their physical and mechanical properties to determine seismovision rational parameters of explosive works. Found that existing guidelines for use of mineral deposits in a complex structure rock mass need to be improved to protect the environment from the harmful effects of seismic waves caused by explosions in mining.The developed algorithm and program for personal computer(PC) for the numerical solution of the problem of wave propagation in a soil massif taking into account wave processes in the detonation products, detonation characteristics of explosives, physical and mechanical characteristics of rock and blasting conditions.The developed mathematical model, algorithm and software for numerical modeling of interaction between waves in the explosion of a system of charges in cylindrical rocks while blasting and briefly delayed the demolition.Mathematical modeling ampltude - the frequency spectrum of the seismic wavelet from the action of single and group explosions of charges of cylindrical symmetry, which instantly undermined or korotkovolnovoi in the mountain range.Investigated the problem of wave interaction group cylindrical charges in an explosion in a rock mass with account of short-delay blasting without it.The obtained analytical formula for the calculation of amplitude-frequency spectra in the explosion of a cylindrical charge of explosives depending on the physico-mechanical properties of rock mass and load parameters.
