Features

1. No wires for power or communications. Battery life of wireless nodes is

3 years for typical applications!

2. Self-forming, self-healing, battery-powered wireless mesh network.

3. 900 MHz RF propagation bends around corners for coverage at the

face without being in the line of fire of blasting.

4. Frequency Hopping (FHSS) RF links mitigate multipath fading caused

by harsh, confined and often obstructed environment.

5. RF transmit power below the 40mW limit set by MSHA for no minimum

distance from blasting caps.

6. Backhaul to surface over narrowband or broadband backbones.

Benefits

1. Quick installation does not interrupt production.

2. Nodes can be installed by equipment operators and/or shift

supervisors with simple tie wrap mounting. No tools are

required to drill holes, install rock bolts, etc..

3. No need to recover/redeploy leaky feeder cable between

blasts, since battery-powered wireless nodes can be

permanently installed between drawpoints, to avoid blasting

line of fire.

4. Offloads data from leaky feeder to fiber, when available.

5. Fast and easy to recover (cutting tie wraps vs. coiling cable).

Truck Cycle Activity

AUR to Callie Dump Avg. Cycle time 33 minutes

Bogger Cycle Activity

1. Number of tonnes bogged

2. Time to first and last bucket

13

Jumbo Analysis – Left and Right Percussion

• Simple install and passive data collection at the face

Critical KPI = Face Utilization

15

Face Utilization Reporting

• Clearly identify bottlenecks in the development and production cycles

• Know when the face is drilled but not charged

• Blasted and clear but not yet bogged (bogger is inactive parked up / no operator) etc.

• Maximum face utilization by shortening each step in the cycle

3 Days of complete face cycle data

16

Face Utilization Analysis

Actionable info to eliminate bottlenecks

1. Arrival/Departure from work areas

2. Alarm sent to shift supervisor if face idle time exceeds a pre-

defined threshold, e.g. 2 hours

3. Accelerated re-entry post-blasting, with remote monitoring of

geotech and gas instrumentation in stope

4. Accelerated backfill, with monitoring of barricade pressure,

paste level and pipe flow to allow continuous pour across

shifts
