提高煤矿许用无起爆药电雷管起爆能力的研究

飞片式无起爆药电雷管在矿山使用中经常出现不能引爆三级煤矿许用乳化炸药的问题。试验证明,飞片式无起爆药电雷管铅板穿孔值约为10 mm,虽然大于8~#有起爆药电雷管的铅板穿孔值(约为9 mm),但实际起爆能力低于8~#有起爆药电雷管,甚至低于6~#有起爆药电雷管。对此,笔者利用加大飞片式无起爆药雷管管壳直径和增加底部装药量的设计,解决了这一难题。

Research on Improvement of Detonating Capability of Permissible Electronic Detonator without Primer

Flying chip electric detonator without primary explosive used in mines often could not detonate tertiary coal mine permissible emulsion explosive.Experiments show that lead plate perforation value of flying chip electric detonator without primary explosive is about 10 mm,which is greater than that of 8# electronic detonator (about 9 mm).However,the actual detonating capacity of flying chip electric detonator without primary explosive is lower than that of 8# electronic detonator,even worse than that of 6# electronic detonator.The problem mentioned above could be solved by increasing shell diameter of flying chip detonator without primary explosive or by improving the innovation of the charge at the bottom.
