摘要
采用“预切割成三区、分段微差间隔起爆、向内定向倒塌”的爆破方案 ,一次起爆 72 89个炮眼、6 89kg岩石乳化炸药 ,使武汉饭店大楼分三个区段按设计顺序先后向院内倒塌 ,周围建 (构 )筑物均安然无恙 。
A blasting program of 'pre-cutting into three districts, sublevel millisecond interval detonation and inward directional collapse' is adopted, of which 7 289 holes were detonated and 689 kg of rock emusified explosive was used, to inward collapse the Wuhan Hotel buildings of three districts in design sequence. The structures around are safe and sound. The blasting engineering is successful.
