| Abstract: | A practical example of directional blasting demolition of a water tower with a weight of 150 tons in a narrow surrounding was presented,by choosing reasonable blasting parameters and the initiation way,implementation of the towers instant recoil,reached the purpose to narrow the scope of the collapse.Through digging the vibration ditch,foreshadowing the buffer layer of security protection measures,reducing the damage of the touchdown blasting vibration and flying rocks hazards,ensure the safety of nearby bu... |
