| 摘 要： | 介绍了在复杂环境下爆破拆除一地下特大钢筋混凝土支撑的技术难点。由于合理选取爆破参数,采取孔内高段、孔外低段毫秒微差起爆网路,安全防护采取覆盖、近体、保护性三种措施,有效地阻止了飞石对周围建筑物的损害,并对爆破可能产生的危害进行了科学验算,最后分多次爆破圆满完成拆除任务。

| Abstract: | This in detail. Based on by the adoption of the three effective tion. The fly rock operations. paper introduced the blasting of an underground outsize underprop in complicated conditions the calculation of the possible harm to the surrounding buildings, the blasting was performed the selected reasonable blasting parameters, the designed millisecond detonating network and protecting measures, namely covering protection, indirect protection and conservative protecwas effectively blocked. The demolition was successfully finished by using multbstage blasting |
