A Smart System for Realtime Miner Tracking and Health Monitoring

Underground mining operations face increased dangers from unidentified medical emergencies together with delayed rescue times due to the lack of real time integrated systems that monitor body health and location. Current safety protocols experience restrictions due to limited visibility together with dangerous environmental factors and weak communication systems. This research fills the essential knowledge gap by building a glove-wearable smart monitoring device which permanently monitors worker vital signs and their real-time movements. A monitoring system composed of an LM75 sensor for temperature checking and a MAX30102 sensor for pulse rate reading along with an MPU6050 module for both movement tracking and fall detection capabilities. Real-time monitoring data passes through NodeMCU ESP8266 microcontrollers to Wi-Fi repeaters and reaches both Flutter-based mobile applications using a Node.js and MongoDB backend system. The system successfully passed tests within simulated underground mining conditions because it exhibited operational stability while acquiring accurate data effectively alerting users in real-time. The analyzed system proves its ability to decrease emergency response delays while improving miner safety because it tracks location and health information in real-time within dangerous environments.
