摘要(Abstract):

介绍了云南铝厂隧道地表的土石方爆破设计与施工,爆破开挖最终边界距隧道拱顶仅17m,地表爆破开挖工程量为12.75万m3。通过合理选择爆破参数,控制最大一段药量,采取有效的安全技术措施,减小了爆破施工对隧道产生的危害。
This paper introduces the design and application of rock blasting on the surface of tunnel at Yunnan Aluminum PlantThe final border of blasting is only 17m away from the tunnel topThe total rock volume of blasting is 127500m3The influence of blasting on tunnel can be avoided or lessened byreasonable choosing of blasting parameters,controlling the most heavy decked charging quantity of every detonating and taking effective and safety measures of technology
