Smart Mines Helmet System

Abstract

Coal mines are considered one of the most dangerous working environments because miners are continuously exposed to toxic gases, poor ventilation, high temperature conditions, and unexpected fire hazards. Many accidents occur due to delayed detection of unsafe environmental conditions and the absence of real-time warning systems near workers. This paper presents an Internet of Things (IoT) based Smart Mines Helmet System that continuously monitors parameters such as temperature, humidity, toxic gas concentration, flame presence, and miner body temperature. A GPS module is integrated to provide real-time location tracking during rescue operations. Sensor readings are displayed on an LCD and uploaded to an IoT monitoring platform for remote supervision. Whenever hazardous conditions exceed safety limits, the system activates a buzzer and relay-based emergency alert mechanism and can also support ventilation through a fan system. The proposed helmet system is a low-cost, reliable, and efficient safety solution that improves worker protection and reduces accident risks in underground coal mines.
