| 摘 要： | 在城区进行小台阶爆破,必须把爆破飞石控制在一定的范围之内。为此,根据爆破破岩理论和现场调研,分析了飞石产生的原因,讨论了飞石的类型。以两个实际爆破工程为例,介绍了针对具体情况所采取的飞石防范措施。实践证明,只要措施得当,飞石是可以控制的。

| Abstract: | In the low-bench blasting in the city proper,the direction and maximum distance of flying rocks must be controlled within certain limits.For this purpose,the causes for flying rocks are analyzed and the sorts of flying rocks are studied based on the theory of rock fragmentation by blasting and the field investigation.Taking two actual blasting projects as an example,precautions against flying rocks,which are taken aiming at the concrete conditions,are introduced.The practice has shown that the direction and maximum distance of flying rocks can be well controlled as long as the reasonable precautions against the flying rock are taken. |
