        abstract = {Mining remains one of the most dangerous professions due to the presence of hazardous gases, structural failures, and poor underground communication. This paper presents the design and implementation of a Smart Helmet for coal miners' safety, equipped with gas sensors (MQ4 and MQ9), an emergency SOS button, a buzzer, and a 16x2 LCD for real-time hazard display. The system utilizes LoRaWAN (SX1278 module) to provide long-range, low-power wireless communication from the helmet to a surface control unit. This wearable IoT-based device ensures real-time environmental monitoring and emergency alerting, enhancing worker safety in underground mining operations. Results show effective gas detection, reliable alert transmission, and low power consumption, proving the system’s viability in industrial applications.},
