摘要(Abstract)：
采用单（多）层、多排、多列条形药包局部辅集中药包的群体布药结构形式、不偶合均匀装药方式、多段毫秒微差爆破等技术，在工程实践中解决了低山缓坡、三面临空、孤岛山丘复杂地形、地质条件下的单（双）向抛掷堆积成型技术难题。
By laying out mono-layer or multiple-layer multiple-row strip-shaped charges as principal and concentrated charging form,at the same time adopting decouple and uniform charges,and MS-delay blasting technique etc.in engineering practice,the technical problems about one-side or two-side directional throw blasting under the complex topographical and geological conditions such as low hill slope,three free surfaces,isolated island etc.have been solved.
