Smart Helmet for Coal Mine Monitoring

Since the beginning, coal mining has gained enormous significance with the growing need for energy and has a long history of adverse health impacts on the miners. Underground mining results in suffocation, gas poisoning, object fall, roof collapse, and gas explosion. Therefore, there is a need for an intelligent monitoring system to eliminate these hazards. This paper proposes a smart helmet based on wireless sensor network for real-time monitoring and coal mine safety from the base station. The system provides instant monitoring of hazardous gases like methane, LPG, CO, temperature, and humidity. Falls are the leading contributor to fatal incidents and sometimes the death of miners as appropriate treatment is not provided within the time set. Hence, the proposed system detects a fall and sends the current location of the miner to the base station.
