INFLUENCE OF DENSITY ON SHOCK SENSITIVITY FOR EMULSION EXPLOSIVES |
| |
| Abstract: | The shock sensitivity of emulsion explosives(EE) is an important index for evaluating EE safety In this study,the card gap test is implemented to determine EE shock sensitivity and the influence of EE density on shock sensitivity is studied With the increase of EE density,the shock strength necessary to initiating EE decreases gradually. That is to say,EE becomes sensitive to the shock waves with the increase of its density |
