城市药壶爆破的控制技术

提出城市药壶爆破采用勤放炮，放小炮，多段微差的松动爆破技术，以及采用适当“多药少爆”的扩壶方法，可以有效地控制爆破危害；同时认为在斜坡复杂岩性条件下，应在装药前进行现场逐孔测量，确定其装药量和扩孔次数，灵活施工，才能真正实现设计要求。

Controlled Technique of Springing Blasting in Urban Area

To conduct springing blast in urban area, this paper suggests that the technique of loosing blasting with more shots, less charging, multi interval millisecond firing should be adopted and the springing should be carried out with proper explosive, less shots in conbination which could control the blasting damage effectively.Each blast hole should be measured before the blasting to decide the explosive amount and springing times in the condition of complex rocks in slope area. And only the implementation is flexible according to the field measurement, the principle of design can be achieved actually.The detail method is introduced by an example.
