BLASTING FOR DIRECTED COLLAPSE OF A REINFORCED CONCRETE PIPE WITH A HEIGHT OF 150 M IN IZHEVSK (UDMURTIA)
The results of directional explosion for collapse of reinforced concrete pipe with a height of 150 m in Izhevsk (Udmurtia) are considered. A new scheme blast hole charges and explosives in weakening zone of the pipe is proposed. Measures enabling directional explosion of smoke concrete pipe in limited sector of breaking-down (equal to 200) and full safety of environment are considered. Formulas and results of the calculations of seismic and air shock waves at different protected objects through explosion and falling of the pipe on ground are described.
