摘要(Abstract):

从解决江西丰城电厂取水口水下开槽爆破的实际问题出发,重点研究并在实践中摸索出了在开槽宽度小.爆破深度大并要求一次爆破成型的情况下爆破参数的选择。采用多段微差交错起爆方式及合理的药孔布设,很好地解决了爆破振动对周围的危害,整个工程获得了成功。
The selection of blasting parameters under the condition of narrow width of ditch to becreated,deeper blasting and requirement for once blasting to the bottom,for solving problems in underwater cut blasting of waterfetching ditch of Fengcheng Power Plant,Jiangxi ProvinceThe problem of hazard to the surroundings from blasting seismic shock has been properly solved by using differential and alternative firing method and rational charged blasthole patternThe whole operation was successful,the practice proved its feasibility
