所谓瞎炮也就是在爆破作业中发生的拒爆现象,也称哑炮。这不仅影响爆破功能,如果未及时发现或处理不当,往往因各种原因引起瞎炮爆炸,造成人身伤亡事故。 爆破作业中产生瞎炮的原因是多方面的,应针对主要原因采取必要的预防措施: （一）起爆材料质量不合格,造成拒爆。如导火索、雷管受潮变质;导火索芯药不匀,有断药现象,电雷管脚线绝缘不良等都能引起拒爆,造成瞎炮。预防措施就是要建立严格的检查和试验制度,对质量不合格的起爆材料不准出库使用。 （二）操作不当引起拒爆,如导火索与雷管接触不严;装药、充塞不当使导火索或导线受损折断;电雷管脚线折断;网路联接错误等都能引起拒爆,造成瞎炮,预防措施就是要提 The so-called blind artillery blasting operations that is, the phenomenon of refusing to explode, also known as dumb guns. This not only affects the blasting function, but if it is not discovered or handled properly, it often causes a blind gun explosion due to various reasons, causing personal injury and death. Blasting operations produce blind artillery for many reasons, should take the necessary precautions for the main reasons: (A) the quality of materials detonated failed, resulting in rejection. Such as fuse, detonator damp degeneration; pyroxene drug uneven, there is off drug phenomenon, electric detonator pinch line insulation and so can cause rejection, resulting in blind artillery. Precautionary measures is to establish a strict inspection and testing system, the quality of substandard materials are not allowed to burst out of the library. (B) caused by improper operation refused to burst, such as the fuse and the detonator contact is not strict; charge, improper stuffing fuse or wire damage broken; electric wire pin broken; network connection errors can cause refusals Explosion, causing blind artillery, precautionary measures is to mention
