Wireless sensors for automated control of total incombustible content (TIC) of dust deposited in underground coal mines
This paper presents ongoing research towards a low-cost/low-power wirelessly enabled
distributed sensing system that can be placed throughout underground coal mines to
potentially measure the total incombustible content (TIC) of the deposited dust. Underground
coal mining operations produce finely divided coal dust, called float dust, which deposits
throughout the mine. This combustible material can be feedstock for coal dust explosions. In
the US, Mine Safety and Health Administration (MSHA) standard 23789 dictates that a TIC of …
