Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Scientific bases control the spatial distribution of the energy of the explosion at the breaking of thin ore bodies Y.P. GALCHENKO The development of technology in the development of breaking the ore vein deposits is limited to the unresolved contradiction between the physically caused the cylindrical symmetry of the distribution of the explosion energy of each charge in the mountain range and technologically caused by unnecessary concentration of power only in destroys the volume limited by the boundaries of the cleaning space. Theoretical and experimental research of opportunities of purposeful control the spatial distribution of the energy of the explosion group of the charges showed that the advanced blasting contouring clearing space charge gives rise to a new effect of occurrence shielding zones, changing character of distribution breaking energy charges in accordance with the requirements of geotechnology. The major controlling factor is the value of the interval deceleration. The influence of this factor on the main indicators of breaking has an extreme character, and the position of the optimum slowing interval in each specific case is determined by the physicomechanical properties of the array destructible. Practical testing of a new method for controlling the distribution of energy in the explosion of breaking veins shown efficacy in the form of increased quantitative and qualitative indicators of breaking at 15-30%.
