Definitions

  • the invention relates to pyrotechnic millisecond delay charge for industrial detonators with explosion delay time of 25 to 1,000 ms from initiation.
  • the charge is intended to be compacted into the delay tube, for detonators initiated by fusehead, by a blasting machine generated pulse, and also for detonators initiated by detonation tube non-electrically - by detonating wave, or by a blasting machine generated spark.
  • It relates to electric detonators in a series connection or a series-parallel connection and to non-electric detonators as well, where the firing circuit is created by connecting of detonation tubes of non-electric detonators, especially in aboveground destruction of rocks, mining in stone quarries, underground mining of rocks and driving of tunnels.
  • the invention also relates to the way of manufacture of the said charge.
  • the invention also relates to electric detonator on its own and is also meant as an independent invention of non-electric detonator, to be used together with the pyrotechnic delay charge.
  • pyrotechnic delay charges containing combustible matter and oxidizer are used. It is altogether Si, B, Zr, Ti metallic powders and Fe+Si+Cr, Si+Se+Fe, Zr+B, Zr+Ni alloys and others that are used as combustibles. Lead monoxide-dioxide and lead dioxide are mostly used as oxidizers. However, such charges contain heavy metals, which get into the environment after the detonator has been used. Therefore, there has been general endeavour aiming at excluding of heavy metals. There are known designs, e.g.
  • the objective of the invention is to develop such a charge and weight ratios of combustible and oxidizer, which would not be intensive in terms of manufacture and costs, with minimum need of completive additives to achieve time variability and delay exactness.

  • the charge is pressed into the delay tube of the detonator under pressure of 280 MPa with the column height of 20 mm.

  • the subject matter of the non-electric industrial detonator with enclosure in the shape of a shell with inserted detonation tube is the fact that in the enclosure there is created a space at least for primary explosive and for delay charge, and the shell, which is closed at the bottom, has a space in the bottom part that has been created for secondary explosive, which space is closed with the delay tube from above.
  • primary explosive In its cylindrical box there is arranged primary explosive, and delay charge is above it.

  • the subject matter of the electric industrial detonator is that in the shell it has a fusehead inserted, with lead-in wires, which are fitted with insulation against the shell enclosure, the other technical features are the same as those of ther non-electric detonator described above.
  • the main advantage is the absence of heavy metals, seeing that the presence of heavy metals even in consumables, e.g. in mineral salt, apparently due to the way of mining, is a great issue in those parts of the world that are actively used for industry.
  • the pyrotechnic charge is free of lead oxides or chromates, and free of barium.
  • the benefit of this solution is that while the above mentioned main advantage is preserved, simplicity of manufacture and versatility of use for various intervals of required delay, even at high accuracy, are provided.
  • the variability of delay is achieved due to the proportion of the basic components and it is not necessaryy to add any other additives. As far as the field of application is concerned, this solution appears to be very simple and practical and not demanding for technology or investment in terms of production.
