DEMOLITION OF 80-METER RC CHIMNEY BY DIRECTIONAL BLASTING |
| |
| Abstract: | A practical example of directional blasting demolition of a RC chimney with a height of 80-meter in a narrow surrounding was presented. The paper discussed the form and position of blasting cuts and the selection of the parameters. The intensity of the ground vibration from the chimney collapsing touchdown was reduced by digging a vibration absorbing trench and using buffering material layer, by which, the workshops located on both sides of the building were protected effectively. |
