About The DigiShot Plus

The DigiShot Plus electronic detonator system is geared for application at medium to large mines where large blasting and remote firing capabilities are required. This accurate, robust and safe electronic system consists of a steel down-line, 2-wire, easy to use detonator.  It can fire a maximum of one thousand eight hundred detonators per blast and has remote firing capabilities.

DigiShot Plus is fully programmable within 1 millisecond increments and the detonator can be set with a delay from zero to twenty thousand milliseconds.

The DigiShot Plus electronic detonator system can be interfaced with DetNet’s technologically advanced ViewShot software, allowing you to conveniently and accurately design and simulate the blast for your own purposes. Last but not least, the bench box can be transformed into a base station and visa versa via software.

Features

The DigiShot Plus electronic detonator is made up of components that are engineered to create a system which is safe, robust, accurate and easy to apply:

• An accurate single electronic detonator with an easy to grip connector, waterproofed with a leakage-free gel, is connected to the inherently safe, portable tagger via a 4 to 2 way converter. A location is assigned to the detonator via the Tagger and, at the same time, it tests for functionality.
• Once all the detonator locations have been assigned, the surface Bus Wire is laid out on the bench and connected to the detonators. The Tagger is connected to the Bus Wire to do a final functionality test for faults of the entire installation. The Tagger is extremely easy to use because of its logical step-by-step software and large buttons.
• The blast layout will then be entered into the Bench Box. This can be done manually off the bench; via the ViewShot software interface; or by connecting the blaster to the installation using the autosearch function, which will automatically retrieve the blast layout.
• Once the blast layout has been inputted into the Bench Box, delays can be assigned manually against each detonator location, downloaded automatically via the ViewShot software interface or inputted via an auto-programmable method, which can be done easily by entering a number of step by step blast design parameters, such as inter hole delays and inter row delays, including whether there are decks present in the blast configuration. At this stage the delays will be assigned to the layout and the Bench Box will be connected to the Bus Wire at either a place of equipment safety or a personnel safety point, depending on the chosen firing position, which can be done via wireless remote from the Base Station to the Bench Box, or directly from the Bench Box.
• Red and Yellow Smart Keys, which are paired and non-interchangeable, are inserted into the control equipment; if the chosen option for blast initiation is a Bench Box, then a Red Smart Key will be used and if the chosen option is remote firing from a Base Station then both the Red and Yellow Keys will be used. The control equipment and Smart Keys are password protected.

Safety Elements

• The detonators have electrostatic immunity; electromagnetic pulse immunity; resistance to radio frequency interference as it’s encrypted to protect against this; resistance to the mains voltage so it will not detonate when connected to an alternative power source; over-voltage protection against lightening; resistance to dynamic shock so there’s no sympathetic detonation between the detonators in the holes; resistance to mechanical shock because the copper casing that encloses the detonators provide mechanical protection; and the detonator connectors are waterproof.
• The inherently safe tagger does not have enough blast voltage to initiate a detonator and doesn’t contain the required encoded firing signal.
• The smart keys come as non-interchangeable pairs, are password protected and provide the physical link that allows the blast voltage to be raised.
• The bench box and base station are password protected; there are software interlocks providing protection from a premature initiation; and the wireless communication between the bench box and the base station is encrypted against radio frequencies, cell phones and other interferences.
