Research on Smart Helmet for Coal Miners with Locking System

The Smart Helmet for Coal Miners with Locking System represents a practical and effective approach to improving worker safety in underground mining environments. The system combines helmet-lock detection, hazardous gas monitoring, automatic work-time recording, and real-time communication into a single wearable device, making it more than just a conventional safety helmet. The paper contributes to creating a safer and more organized working environment while encouraging better compliance with workplace safety practices. The proposed smart helmet demonstrates how affordable IoT technology can be integrated with personal protective equipment to improve workplace safety, reduce operational risks, and support better monitoring in hazardous environments. It offers a reliable foundation for smarter mining practices and highlights the importance of combining technology with safety to protect workers in challenging underground conditions.
