DISCUSSION ON NOMINAL DELAY INTERVALS OF NONELECTRIC MILLISECOND DETONATORS
Yang Xiang-qu · Engineering Blasting · 2003
From respects of delay time and priming circuit for millisecond blasting,the factors that should be considered when setting the nominal delay intervals of nonelectric millisecond detonators are studied The practical problems met in application of existing nonelectric millisecond detonators are pointed out Some proposals for resetting the nominal delay intervals of nonelectric millisecond detonators are put forward
