Abstract
Based on the theory as well as model test and engineering practice, some major techniques on cutting blasting and smooth blasting in rock tunnel are discussed . The reasonable cutting form and cutting blasting parameters, the reasonable charging structure for smooth blasting and the parameters , the reasonable delay time of millisecond blasting are put forward in this paper.
