IOT Based Coal Mine Safety Monitoring and Alerting Smart Helmet

Abstract

"Coal mining remains one of the most hazardous occupations, with workers exposed to numerous safety threats such as toxic gases, high temperatures, low visibility, and potential structural collapses. This research presents the design and development of a smart helmet aimed at enhancing coal mine safety through real-time environmental monitoring and communication capabilities. The helmet integrates sensors for gas detection (e.g., methane, carbon monoxide), temperature and humidity monitoring, and an accelerometer for fall or impact detection. It also features wireless data transmission to alert supervisors in case of abnormal conditions or emergencies. The proposed system seeks to minimize risk and improve response times during incidents, contributing to a safer mining environment. Experimental validation in simulated mining conditions demonstrates the system's effectiveness and reliability.
