摘　　要：为在复杂环境下实现岩石路堑爆破快速施工，作者采用了微差松动与挤压相结合的爆破新技术，取得了很好的效益。本文论述了该技术的实质与效果，并讨论了其主要参数装药结构与装药量、起爆时差的确定原则与方法，具有较大的理论与实用价值。The quick blasting construction and good beneficial results are achieve by the new technique of combining the millisecond delay loosing and buffer blasting in complexenvironment. The substance and results of new technique are introduced in the paper. The prindple and method of determining blasting parameters, structure and quantity of the bore-holecharging and delay of detonating, are discussed. It has great theoretical and practical value.
