Li-Fi Technology for Enhanced Communication and Safety in Coal Mining

In the coal mining industry, numerous hazardous risks such as gas explosions, temperature fluctuations, and humidity variations pose challenges in terms of monitoring and control. This paper introduces a proposed method that utilizes Li-Fi technology for data transmission. Equipped with sensors, this system provides real-time situation updates to coal miners, ensuring their safety. Among the dangerous gases in coal mining, carbon monoxide (CO) is a significant concern. To address this, specific sensors are employed and connected to a core component, the microcontroller, which is strategically placed throughout the coal mine. When the concentration level exceeds a predetermined threshold, an alarm is triggered, and a notification is sent to the central database, alerting the workers. By overcoming issues like slow data transmission or data loss, Li-Fi offers a solution that enhances safety and improves working conditions for laborers in the coal mining sector.
