 CUSTOMER BENEFITS
 Number of Detonators Fired
 Up to 28,000 • Able to increase production time up to an hour a day. at One Time
 *BCU—Blast Control Unit • Improved safety and security because BlastWeb allows for blasts to be initiated from
 the surface while requiring a password and smart key to initiate. • Allows for multiple blasting options—compatible with Dyno Nobel’s electronic
 initiation systems: DriftShot™, SmartShot™ and DigiShot® Plus. Dyno Nobel’s NONEL®
 line and detonating cord via DriftShot™ Starter. • Easy instillation to available communication systems on site. BlastWeb can
 communicate over WiFi, Ethernet, copper, fiber and leaky feeders. • Continuous communication between BCU, Surface Blast Controller (SBC) and
 Applicable Standard detonators allows for status feedback so maintenance can be conducted on
 BCU passes tests specified in: damaged firing cables.

TECHNICAL DATA SHEET
BLASTWEB™ PRODUCT DESCRIPTION
 BlastWeb™ is an electronic networking system designed
Underground Electronic Networking to reduce costs by decreasing time spent on production and development blasting
 in underground mining operations. This centralized blasting system is the most
 sophisticated system available, having the capability to: communicate on different
 platforms, initiate up to 24 Blast Control Units (BCU) and reduce production time by up
 Properties to an hour a day. It also improves safety allowing for blasts to be initiated above ground
 or in a distant safe location.

Surface Blast Controller (SBC) Smart Keys
 • Ability to fire multiple BCUs (up to 24) from a • Encrypted signal to initiate detonation with
 centralized point, either from surface or underground specific password
 • Continuous communication with all connected BCUs • Minimum time delay of two minutes
 at the underground work place, providing real-time • Two different smart keys to allow for initiation
 information on all connected components to take place on the surface or underground.
 • Logging of all events and generation of blast reports The red smart key initiates from the BCU, while
 the yellow smart key allows for centralized
 blasting from the SBC
