A miner's light was essential to their labor. Without light there was no sight, no work, and no wages. But this essential light was also lethal. Open flames could ignite the inflammable gas especially prevalent in coal mines and mining explosions with hundreds of casualties was a common occurrence in the late 19 th and early 20 th century. Miners often carried open flames into the mines in ...

a result, in many parts of the world, coalbed or underground mine fires have burned uncontrollably for decades. There is no one best method to control coal fires, but several approaches have been tried. For nearsurface fires, combustion may be contained by excavating the fire, but this can be expensive and disruptive to the environment, especially in the case of large fires. Another approach ...

Mary McMahon Entrance to a coal mine. Underground mining is a technique used to access ores and valuable minerals in the ground by digging into the ground to extract them. This is in contrast with techniques like open pit mining, in which the surface layers of ground are scooped away to access deposits, or mountaintop removal, in which the top of a mountain is simply shaved off to access the ...

· Light Sources in Mining. In 1879 a practical incandescent filament lamp was patented. As a result light no longer depended on a fuel source. Many startling breakthroughs have been made in lighting knowledge since Edison's discovery, including some with appliions in underground mines. Each has inherent advantages and disadvantages. Table 1 ...

mining mining Ventilation and lighting: Ventilation is an important consideration in underground mining. In addition to the obvious requirement of providing fresh air for those working underground, there are other demands. For example, dieselpowered equipment is important in many mining systems, and fresh air is required both for combustion and to dilute exhaust contaminants.
· Over the years, several miners, such as those involved in the Sago and Darby mine explosions, have survived an initial disaster but perished before they could escape or be rescued (Gates et al. 2007; Light et al. 2007). As part of a recent study by Ounanian (2007), coal mining accidents from 1970 to 2006 were reviewed. The review identified 37 events during this time period in which at ...
