Design and Implementation of an IoT-Based Coal Mine Safety and Alert System for Improved Miner Safety

Coal mining is one of the most hazardous industrial activities, often exposing workers to life-threatening conditions such as toxic gas leaks, high temperatures, and equipment failure. To enhance miner safety and minimize accidents, this paper presents the design and development of an IoT-based coal mine safety and alert system [1]. The system integrates various sensors to monitor environmental parameters including methane gas concentration, carbon monoxide levels, temperature, and humidity [1]. Data collected from the sensors is transmitted in real-time to a central monitoring system using wireless communication modules [2]. In case of abnormal conditions, immediate alerts are sent to both miners and surface control units through alarms and mobile notifications [2]. The system enables early detection of potential threats, facilitating timely evacuation and response. By leveraging IoT technology, the proposed solution aims to improve operational safety, reduce manual inspections, and enhance decision-making [3]. The design is cost-effective, scalable, and adaptable to various mine environments. This approach contributes significantly to building a smarter and safer mining ecosystem [3].
