复杂环境大区深孔台阶爆破技术

为了总结复杂环境大区深孔台阶爆破技术的特点,掌握爆破参数选择,爆破网路设计,安全防护设计及施工组织等方面的技术要点,分析并介绍了长峙岛外长峙山体开挖、万向石油岙山油库区开挖和小干岛围垦采石工程剩余山体开挖的工程实例。得到结果为:复杂环境大区深孔台阶爆破技术特别适用于爆破安全警戒难度大,民扰问题突出的城区土石方爆破工程,有利于提高劳动力和机械设备的使用效率,取得良好的经济、社会效益,对类似工程的设计与施工具有借鉴意义。

The bench blasting technique of large-scale deep-hole in complex environment

For summarizing the key technological points of the bench blasting technique of large-scale deep-hole in complex environment, the selection of blasting parameters, firing circuit design, safety protection design and construction organization etc, three cases were analyzed and introduced of Wanxiang Petroleum Aoshan oil depot area excavation,Changzhi Island Waichangzhi Mountain excavation and the remaining mountain of Niutou Mountain excavation. The conclusion that the bench blasting technique of large-scale deep-hole in complex environment was particularly applicable to rock and soil blasting in urban areas where blasting safety guard was difficult and residents interference was serious and was beneficial to improve the efficiency of labor and mechanical equipment and could achieve good economic. It could provide reference to the design and construction of similar projects.
