BlastWeb® .4G

The BlastWeb^® .4G system consists of Hardware Control Equipment modules (BCUs) installed at suitable underground sites, linked together through available communication networks to facilitate communication between the surface PC (Surface Blast Controller) and BCUs (Blast Control Units) underground.

System components

Red SmartKey

The Red Smartkey contains the required blast command and coded signal, which enables users to use BCUs in a standalone mode.

Yellow SmartKey

Blast Control Unit (BCU)

The Blast Control Unit (BCU) provides the required blast voltage and encoded signal necessary to initiate the blast. The BCU can be used in a standalone or remote blasting mode, blasting a maximum of six blasting points from a point of safety using a Red SmartKey. The BCU can be powered from 110, 220, or 525 V and incorporates a battery back-up system in case of power failures. The BCU can link via a Copper or Ethernet backbone to other BCUs and a Surface Blast Controller to form an integrated communication system which enables users to have access to real time information on all events occurring and to blast the entire installation from a central point.

Surface Blast Controller

The BlastWeb^® Surface Blast Controller allows centralised blasting to take place from the control room and is password protected. The Surface Blast Controller collects, displays and stores all events on a real time basis and supplies warnings of all faults or errors on the system enabling users to do fault diagnostics and fix all problems before blasting time. The Surface Blast Controller sends the blast instruction to all selected BCUs when prompted by the blaster. It also compiles blast reports to supply blast information.

System Benefits

The BCU is designed with 6 independent channels, which can service 6 individual blasting points blasting a maximum of 200 electronic delay detonators. This gives the BCU a maximum capability of 1200 electronic detonators.
Due to user demand and realising the importance of recorded data for use on Management Information Systems the system provides a web interface allowing the seamless access of information to mine management.

Initiators and detonators

The Blastweb® system supports the following products:

Initiators

Starters

DetNet offers our channel partners their own branded range of starters.

Features

Starters form part of the 3rd Generation Electronic Detonators Blasting System, and is designed solely to initiate Shocktube or Nonel
With its specialised connector, Starters enables the initiation of multiple panels and reak time confirmation of a successful blast communicated via a computer network.
The starters requires a specific coded signal to fire.
It offers over-voltage protection and is safe to handle.

4G Detonator

The new generation 4G Detonator is a fully programmable electronic detonator that is suitably tailored to fit all types of blasting operations. The design has evolved from the remarkable safety principles of the 3G detonator.

Redesigned Application Specific Integrated Circuit (ASIC) with 15 times more memory, which allows the storage and tracking of identification numbers.
Delay time and unique ID is fed directly into the detonator during on-bench tagging.
Verification of sufficient firing voltage at the furthest detonator, before the user presses the fire keys.
Down-hole wire length and other critical information is stored in the expanded non-volatile memory during detonator assembling.

Features and benefits

Reduces production blast times. Up to 24 BCUs can be fired in a single setting and up to 28 000 detonators can be initiated.
Safety and Security. A unique password and specific SmartKey is required for blast initiation.
Compatible with multiple communication backbones. WiFi, Ethernet, Copper, Fiber, Leaky Feeder.
Easy to use. It has the ability to remotely upload new firmware without disrupting operations.
