Underground Operational Trials Validate Headings Management Technology

December 1, 2025

Safecrete Technology completed successful underground operational trials at Lady Loretta mine, validating the headings management system's performance in real operational environments.

Over two days underground, the trial programme deployed 12 sensors into freshly sprayed shotcrete, testing operational efficacy and demonstrating that sensors survive harsh underground conditions whilst reliably transmitting data to cloud systems.

The trials also pioneered on-site beam end testing methodology, enabling maturity curve calibration underground without laboratory samples whilst capturing critical early-stage strength development data during the first four hours of curing.

Operational Environment Validation

Validating monitoring technology requires testing in actual underground mining environments where sensors face harsh conditions, operational workflows, and real-world deployment constraints.

Underground Trial Objectives

Prove sensors survive shotcrete application process and harsh underground environment including moisture, vibration, and physical stresses.
Validate reliable data transmission from underground locations to cloud systems through mining infrastructure and network constraints.
Demonstrate on-site maturity curve calibration capability using beam end testing, eliminating laboratory dependency and capturing early-stage strength development.

Successful Trial Outcomes

All 12 deployed sensors survived shotcrete spraying and underground conditions, proving robust design for operational deployment.
100% data transmission success rate demonstrated reliable cloud connectivity and system performance in underground environment.
Underground beam end testing successfully created maturity curves on-site, capturing critical first four hours of strength development without laboratory delays.

Underground Operational Trial Programme

Sensor Deployment and Survival Testing

The two-day underground trial programme at Lady Loretta mine deployed 12 headings management sensors into freshly sprayed shotcrete under actual operational conditions. Sensors were activated and placed into shotcrete batches before application, then survived the high-pressure spraying process, physical impact against tunnel surfaces, and the harsh underground environment. All 12 sensors remained intact and functional throughout the trial, demonstrating robust engineering design suitable for demanding mining applications.

Cloud Data Transmission Validation

Critical to operational deployment, all 12 sensors successfully transmitted continuous temperature data from underground locations to Safecrete's cloud platform throughout the monitoring period. The 100% transmission success rate proved the technology's ability to function reliably despite underground network constraints, infrastructure limitations, and physical barriers that challenge wireless communications. Real-time data visibility enabled remote monitoring of strength development without requiring personnel to return underground for data collection.

Underground Beam End Testing Innovation

The trials pioneered on-site maturity curve calibration using beam end testing conducted underground rather than in surface laboratories. This methodology enables mining operations to create calibrated curves without sending samples off-site, significantly reducing turnaround time whilst capturing strength development data during the critical first four hours of curing—a period typically missed when samples must be transported to external testing facilities. This innovation removes laboratory dependency and accelerates technology deployment timelines.

Operational Readiness Confirmation

The successful Lady Loretta trials confirmed Safecrete's headings management system achieves operational readiness for deployment in underground mining environments.

The combination of sensor survivability, reliable data transmission, and innovative on-site calibration methodology positions the technology for commercial rollout to underground mining contractors and operators worldwide.
