为合理降低成本,减小大块率,以长江某护岸工程土石方爆破设计与施工为例,采用现场混装铵油炸药及中深孔微差爆破技术,进行爆破参数的设计与爆破危害的控制,讨论现场混装炸药的应用情况。实践证明,现场混装炸药的使用安全可靠,可有效减少大块率,提高爆破后石渣装运效率,保证经济效益与社会效益。
為閤理降低成本,減小大塊率,以長江某護岸工程土石方爆破設計與施工為例,採用現場混裝銨油炸藥及中深孔微差爆破技術,進行爆破參數的設計與爆破危害的控製,討論現場混裝炸藥的應用情況。實踐證明,現場混裝炸藥的使用安全可靠,可有效減少大塊率,提高爆破後石渣裝運效率,保證經濟效益與社會效益。

Taking rock blasting designing and construction of the Yangtze River revetment engineering for example ,in order to reduce the cost reasonably and the rate of large rock ,discuss the situation of spot mixed explosives ,which adopted technology of mixed anfo explosives and millisecond blasting in medium deep hole and controlled the design of blasting parameters and harm. Practice has proved that the application of on‐site mixed explosive is safe and reliable ,w hich can effectively reduce the rate of large rock ,improve the efficiency of stone slag shipment after blasting ,ensure economic benefit and so‐cial benefit.
