Description
 Weight (BCU) ± 50Kg
BlastWeb™ is an electronic blasting system specifically designed for underground
blasting operations. The BlastWeb system can be used to initiate Dyno Nobel
electronic detonators, as well as detonating cord via a DriftShot™ Starter, allowing Dimensions (BCU) L = 540mm; W = 480mm; H = 730mm
for initiation of multiple development faces and production blasts. The BlastWeb
system can be used as a stand-alone system or as part of a centralised blasting SmartKey; USB; (RS-232 & RS-485 for

The BlastWeb system consists of the following main components:
 Water Resistance (BCU) Splash proof (IP64)
Blast Control Unit (BCU) which provides:
 Upstream communication to surface via various communication networks;
 Downstream communication to terminators and initiators via the blasting 2-wire Terminator which provides:

 Continuous communication with all connected BCUs at the underground
 work place, providing real time information on all connected components;
 Logging of all events and generation of blast reports.

on surface or at the BCU.
The 6-channel BCU can fire most Dyno Nobel electronic detonators, viz Applicable Standards
SmartShot®, DriftShot and DriftShot Starter.
 Detonator passes tests specified in:
All events are logged by both the BCU and the Surface Blast Controller. The SANS 1717-1 (South African National Standard for The Design and Approval
Surface Blast Controller is capable of generating blast reports at any time. of EDD initiation systems for use in mining and civil blasting); and
The ability to fire from surface allows the mine to clear prior to firing, ensuring CEN 13763-27: European CEN-testing specification for Explosives for civil
personnel safety. uses – detonators and relays.

The BlastWeb system is able to use existing communication systems installed
on customer sites.
An added feature is the ability for the BCU to control the switching of
underground fans and pumps.
Constant communication feedback throughout the shift on the status of the
detonators allows maintenance to be conducted on damaged firing cables, thus
ensuring all shots are fired successfully.
