Abstract
The controlled blasting is adopted for the reinforced concrete foundation of a building.Based on the selection of the suitable blasting parameters and the loaded constitution,the reasonable firing method and detonation sequence of the blasting demolition engineering close to roadway are put forward.The techniques of millisecond blasting and safety measures of reducing vibration and controlling blasting f1ying rock are put forward.The house and establishment is safe after blasting.The explosive effect is satisfactory.The experience provides the reference for the similar blasting engineering.
