Safety Monitoring and Auto Alert System in Underground Collieries

Abstract

In the current scenario, significant mine disasters often occur due to explosions and fires. The occurrence of unexpected underground mine landslides poses a significant threat to miner safety, leading to fatalities. Consequently, the proposed system actively monitors key parameters and issues alerts to miners, aiming to mitigate this risk. The system primarily focuses on monitoring gas levels, air quality, temperature, and vibrations in underground mines, with the data being continuously recorded and stored in the ThingSpeak cloud. Visualization of the data is achieved through field charts created within the designated channel. The cloud-stored data is linked with MathWorks to predict missing values, providing a basis for proactive measures. The predicted missing values are then stored in a separate channel on ThingSpeak for continuous chart visualization. This data, complete with timestamps, can be exported to excel for further analysis and application. The scenario of the coal mine is monitored and regular reports are sent to the personnel’s mail which is automated in Thingspeak. In the event of an explosion, the rescue team is promptly notified through SMS alerts using a GSM modem.
