Abstract
The present invention relates to a method for the use of waste non-electric shock tube as a product
/additive, suitable for blending with existing explosive products as a filler or a fuel, which ultimately
facilitates the elimination of the non-electric shock tube waste being disposed of by burning or by
dumping into land fill. The method allows for the availability of a cheaper and a more cost-effective
explosive product additive then currently in use in the industry, and eliminating waste and pollution.

Explosive Recycle Additive
Field of the invention The present invention relates to a method for the use of waste non-electric shock tube as a product /additive, suitable for blending with existing explosive products as a filler or a fuel, which ultimately facilitates the elimination of the non-electric shock tube waste beingdisposed of by burning or by dumping into land fill. The method allows for the availability of a cheaper and a more cost-effective explosive product additive then currently in use in the industry, and eliminating waste and pollution.
Definitions
Non-electric Shock Tube: Plastic shock tube filled with a chemical mixture capable of burning at velocities in excess of 1500mts/second. Used to initiate a detonator and available in varying lengths
Non-Electric Trunkline Surface Delay: Plastic shock tube filled with a chemical mixture capable of burning at velocities in excess of 1500mts/second Used to initiate a non-electric surface delay detonator used for interconnecting of blast holes in a blast.
Non-electric detonator: Down hole detonator or trunkline delay detonator initiated via plastic shock tube filled with a chemical mixture capable of burning at velocities in excess of 1500mts/second.
Lead in line: Main Surface firing line. Plastic shock tube filled with a chemical mixture capable of burning at velocities in excess of 1500mts/second, used to initiate a detonator and generally available in spools with varying long lengths.

Background of the invention:
Non-electric shock tube has been used through-outthe world in many countries and for many years and although alternative products are coming onto the market, this product will still be in the industryformany more years.The issue of the waste generated by left over plastic tubing, that has either not been consumed in the blasting process or, has been generated by over supply of this product intothe explosives market, has usually been disposed of by either dumping into land fill or destroyed by burning.
In othercases, due to the short shelf lifeof non-electric detonators (approx.:1-3years) and variation of timingchange, etc. products are being presented fordisposal thereby substantially increasing the level of waste. These products require the removal of all detonators prior to the disposal of the remaining non-electric shock tube waste.
The dumping of this waste into land fill is not desirable as the product (which is plastic) does not breakdown with time. Additionally, when destroyed by burning emits unwanted toxicgases into the atmosphere, again not desirable in an era of concerns of global warming. Even disposal by burning will generally still leave some plastic residue.
The method of this invention of convertingthe waste non -electric shock tube intosmall granuleswill allowforthis productto be added to existing explosive products, where it will be totally consumed in the blasting processthereby leaving no residue, no toxic emissions, or long-term problems from dumping into land fill.
Another benefit of this invention is, the granulated waste non-electric shock tube can be utilised as a energy diluting agent to reduce the energy in special blasting applications.

Summary of the Invention
Current Technical problems:
Waste Disposal- Burning: once the Non-electric shock tube initiation system is used atthe blastsite location, the non-electric shock tube becomes a waste. Current treatment of this waste generally involves burning which produces dangerous toxic gases which are released into the atmosphere. This method is undesirable in an era of global warming concerns.
Waste Disposal - Land Fill:The alternative method fordisposal isthedumpingof non-electric shock tube intolandfill which does not eliminate the waste problem as the plastictubing does not break down in land fill and only stores the problem to be dealt with in the future. Additionally, the treatment also involves some additional costs.
Solution to problems The present invention addressesthe current treatment given to the waste shock tube by extending its use as raw material for explosives. The waste shock tube can be used, after modification, as an alternative fuel or energy diluting agent (Density Modifier) in explosives. In both cases explosives could achieve different performance, which may not be available with the current technology. But more importantly, the waste shocktube will be consumed during the detonation process and thus, prevented from going to landfill or burned.
Density Modifier: By granulatingthe non-electric shock tube itcan be added to an explosive product as a density modifierto improve performance ordecrease energy in special blasting applications. It may also provide for more cost-efficient blasting as a cheaper additive when compared to current available density modifiers.
Alternative Fuel: With research and modification the fuel qualities of the Non-electric plastic waste could be used to either supplement or replace existing fuels in use in current explosives thereby reducing costs of current fuels and reducing waste issues.

Invention Details:
Non-electric shock tube, after removal of detonators and explosive devices, (the waste) is put through a process (Cut, Milled, Granulated, Powdered, etc.) and is sized through screening to commensurate with requirements, and packaged as per requirements.
The waste can then be added to explosive products via manual ormechanically measured processes to ensure consistent blends to produce consistent performance of explosive products.
This process will extend the useful life of waste shock tube and in addition, it will allow for elimination of non-electric shock tube to be disposed of via current disposal methods of burning and, also of waste dumping into land fill thereby eliminating pollution.
