台阶深孔微差爆破在港口工程中的应用

台阶深孔微差爆破是一种大规模、快速的土石方施工方法。本文就连云港庙岭开山填海建港工程中，台阶深孔微差爆破技术的应用情况、多年来的施工经验体会作了介绍，并对一些爆破理论进行了讨论。另外，就爆破工作在管理上存在的问题和改善管理后取得的效果作了分析。

Application of deep-holed millisecond blasting in port construction

Deep-holed millisecond blasting is a fast construction method applied to large scale earthwork. Its applicatron in the construction of a cross-sea dam in Lianyungan port for blastion hills and the construction experiences over the years are introduced. Some explosion theories are discussed.Analysis is made for the old manage ment system hampering blasting effectiveness and the better basting results achieved by improving the system.
