The Problem
The client had zero real-time visibility into equipment health, air quality, or worker location across 4 underground mines. Unplanned equipment failures caused 3-4 days of downtime per month, costing millions in lost production.
What We Built
We designed and deployed a ruggedized LoRaWAN mesh network across 12km of tunnels. 340 wireless sensors monitor air quality (CO, CH4, O2), vibration on critical machinery, and worker locations via RFID. Edge computing aggregates data before forwarding to a Grafana dashboard with automated WhatsApp alerts.
The Outcomes
Within 6 months, unplanned downtime dropped 41%. The early-warning vibration system flagged 3 imminent conveyor belt failures before they occurred, preventing Rp 4.2 billion in costs. Air quality alerts reduced worker health incidents by 67%.
"The real-time visibility Asiateknologi delivered underground has fundamentally changed how we operate. Our safety record improved dramatically."
