Zig-Bee Based Intelligent Helmet for Coal Miners

In recent days coal mining has been very dangerous activity for the workers. Who work in mine. Because of numbers of adverse effects an the environment. During mining operation dangerous gases. Like methane may be released into the air also underground mining hazards. Include suffocation, gas poisoning, roof collapse and gas explosion by keeping all those activity which done in underground coal mine we designed a system i.e. Zig bee based intelligent helmet for coal miners [7]. For monitoring hazard gases, temperature condition and humidity. Level in air the improve safety features in our system dramatically increases life expectancy by alerting them about hazards. In this system, the helmet has three sensors temperature sensors, humidity sensor and gas sensor to monitor the condition in coal mining. If there is any hazardous condition occurs the buzzer get alarm which is positioned on helmet then gives the information to control station through the zig bee transreceiver [6]. So that miners have the chance to rescue his life from the hazards occurs in coal mines.
