DEMOLITION OF A GROUP OF REINFORCED CONCRETE FRAME BUILDINGS BY BLASTING METHOD |
|
| Abstract: | A group of reinforced concrete frame buildings including distilling tower,sulfur evaporating and scrubbing shops was demolished by the blasting scheme with once through initiation,disintegration in the air and directional collapse The calculation of blast cut height,selection of blasting parameters,design of blasthole pattern and priming circuit,safety check and precautionary measures were presented in this paper |
