Nonel detonators
Delayed two-way non-electrical (nonel) detonators are detonators that initiate the explosive and create a delay between one borehole and the next.
Each unit comprises two detonators – one at each end – which are connected by a PVC tube filled with explosive. The upper detonator has a clip for fast attachment with up to six fuses in different colors, depending on the delay. The second side has a long-delay detonator that is inserted into the accelerant to avoid halting the explosion.
Use options
Use for all kinds of work where the distance between boreholes is big enough (at least one meter)
Use in places where there is static electricity risk (lighting, power pylons, etc.), and where there is high humidity
Use in metallic areas (areas where the rock contains metals)
Advantages
- Excellent water resistance
- Optimal delay control
- Rapid clip connection saves charging time
- Safe: is not affected by static electricity friction or blows
- Easy and convenient to use and transport
- Allows a large number of delays to better use the explosives and prevent ground tremors
Sensitivity and initiation
Delayed detonators are very safe to use, because are not affected by static electricity. The detonators can be initiated either by a special explosion for nonel detonators, which do not use electricity, or by a detonator.
Safety and transportation
Delayed detonators can be transported and used pursuant to Explosives (Trade, Transportation, Manufacture, Storage, and Use) Regulations, 5754-1994
Technical data
