In recent days coal mining has been a very dangerous activity that can result in a number of adverse effects on the environment for example during mining operations methane, a known greenhouse gas, may be released into the air.
Underground mining hazards include suffocation, gas poisoning, roof collapse and gas explosions. Keeping all these aspects in mind we designed a system, i.e. smart helmet using zigbee technology for monitoring the hazardous gases, abnormal temperature conditions and the humidity levels in the air.
The improved safety features in our system dramatically increased life expectancy of the coal miners by alerting them about the hazards. In our system, the helmet is having the circuit with three sensors i.e. temperature, humidity and gas to monitor the conditions in coal mine.
If there is any hazardous situation in the mine the helmet gives the information to the control station through the zigbee transmitter and the control station will alert the coal miner using the zigbee receiver by making the buzzer active which is positioned in the helmet so that a miner can have a chance to rescue his life from the hazards occurred in coal mines.
