复杂环境下的控制爆破安全技术

Controlled Blasting Safety Technology in Complex Environment

城市控制爆破中碰到了作业空间小、周围环境复杂、对爆生灾害控制要求高等问题。通过对问题的分类分析,结合实际工作情况提出了分区爆破、孔外孔内同时微差爆破、合理控制微差时间等手段,有效地克服了环境困难,成功地完成了爆破工作。

Many difficulties exists in city blasting,such as complex environment,small workspace and high requiurements of hazards controlling.Based on analysis of problems and considering practical situation,this paper puts forward some safety measures,means of zoning,millisecond detonation ciruit inside and outside hole and reasonable millisecond delay,to effectively conquer the difficulties of environment and successfully complete the blasting.
