| Abstract: | This paper presents an example of demolition of high frameworks in complicated surroundings by blasting to reach directional falling into the controlled collapse scope. In the blasting the collapse-reaching scope, the base backward movement and the horizontal movement of the frameworks were effectively controlled by selecting or determining the blasting parameters as the rational heights of demolition, the rational height difference in demolition, the rational detonating sequence, the rational detonating time difference between parallel rows, and optimized demolition parameter and charge structure. |
