摘要
通过预裂爆破工业试验比较实践,阐述大孔径线型聚能预裂控制爆破的设计原理及方法,指出该新技术能有效提高预裂面成缝质量。
In this article, the author compares the presplitting industry experiments with practice, exoatuates the principles and methods of the big - aparture linear energycavity controlled blasting. It is points out that the new technique can improve the quality of the presplitting surface effectively and has a reference significance.
