【Abstract】 This paper discusses how to select blasting parameters and how to control recoil when demolishing a 60m bricked chimney. Practice showed that when reasonable blasting parameters are chosen, it is possible, using controlled blasting, to control recoil while the chimney is collapsing, This paper offers reference for directional blasting demolition of high-rise structures under complicated environment.更多还原
