The coal mining industry faces numerous occupational hazards, with worker safety being a paramount concern. In response to this challenge, this paper proposes an IOT-based Coal Mine Worker Monitoring System (CMWMS) designed to enhance the safety and well-being of coal miners. The system integrates wearable sensors, wireless communication, and data analytics to continuously monitor vital signs, environmental conditions, and location information of mine workers in real time. Through the deployment of wearable devices equipped with sensors for measuring physiological parameters such as heart rate, body temperature, and respiratory rate, along with environmental sensors for detecting gas levels and ambient temperature, the CMWMS provides comprehensive monitoring capabilities. Data collected from these sensors are transmitted wirelessly to a central monitoring station where sophisticated algorithms analyze the information for early detection of potential health risks or hazardous conditions. Additionally, the system incorporates geo-location technology to track the movements of miners within the mine, enabling rapid response in case of emergencies such as accidents or cave-ins. By providing timely alerts and actionable insights, the IOT-based CMWMS empowers mine operators to proactively manage safety risks, mitigate accidents, and safeguard the well-being of coal mine workers. This paper discusses the architecture, components, and functionalities of the proposed system, along with its potential impact on improving safety standards in the coal mining industry.
