| Abstract: | Through researching into non-electric detonating network system applied in Nanfen Iron Open-pit Mine,the reliability indices for six detonating elements and their connectors common in blasting of open pits are determined.In the light of the features of production blasting in Nanfen mine,four typical Nonel relay detonating network systems are proposed,and two systems of them are used and evaluated in site.The results show that two detonating network systems with high reliability are obvious in reduction of blasting vibration and possible to ensure the safety of 290m adit.In addition,the evaluation criterion and calculation method for reliability of a detonating network system are introduced. |
