    Toxic Gas Sensors Replace Canaries and Mice in Mines

    Toxic gases are very often released in underground mines and cannot easily be detected by human senses. Gas in mines is naturally produced during the conversion of organics to coal. It is not only in the mine’s atmosphere, but is also absorbed into coal’s inner surfaces. When released during mining, fire and explosion are a potential result.
