The safety of mine workers is a major concern in the modern world. The life and health of miners are vulnerable against a few fundamental problems, such as their workplace and its adverse effects. A novel and inventive approach is needed to increase profitability and reduce mining costs while keeping worker safety in mind. For tracking the level of concentration of hazardous gases, semiconductor gas sensors are used. In the mine worker area, air contamination is primarily caused by outflows from particulate matter and gases, such as sulfur dioxide (SO 2), nitrogen dioxide (NO 2), carbon monoxide (CO) furthermore, the goal of this project is to design a real time IOT system that can monitor temperature, humidity, dangerous gasses, and smoke status in an underground mine utilizing sensors with an ODROID-N2+controller and designed a base station to receive data from all coal mines via the ODROID-N2+module. We also built a web-based interface accessible through computers and Android/iOS devices. The suggested system seamlessly integrates surveillance, analysis, and localization strategies using cloud computing, application gateways, real-time operational databases, Internet of Things (IoT), and application program interfaces to enhance the management of safety and prevent injuries in underground coal mines.
