Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Justification of the method control the longitudinal distribution of the explosion energy at crushing of the rock mass Y.P. GALCHENKO Need to establish and use technological methods for density control, direction and shape of the energy flow in the explosive destruction of ores and rocks in open cast mining, caused the complexity of the geometry of destructible of rock mass areas. Investigation of the factors and conditions that affect the distribution of the explosion energy of cylindrical charges in time and volume showed that the existing geotechnologies a relative measure of excess energy in the charge increases in direct proportion to the height of the ledge and inversely proportional to the angle of its slope. Management of distributed energy explosion uncovered by the use of deconcentrated charges. Theoretically grounded methodology for determining the parameters of these charges, provide a linear correlation between the concentration of the total energy with the changing height ledge the load on a charge. Experimental verification of the proposed control methods showed the possibility of reducing the consumption of explosives, which will increase with the height of the ledge and with decrease in the angle of his slope. Key words: open pit, management of energy explosion, deconcentrated charge, consumption of explosives. Contacts: E-mail: schtrek3@yandex.ru Pp. 46-51.
