Dust explosion - Wikipedia

19 rows  2007-04-05  Mining of coal leads to coal dust, and flour mills likewise have large amounts of flour dust as a result of milling. A gigantic explosion of flour dust destroyed a mill in Minnesota on May 2, 1878, killing 18 workers at the Washburn A Mill and another four in adjacent buildings. A similar problem occurs in sawmills and other places dedicated to woodworking. Since the advent of industrial ...

Spontaneous Heating and Fire in Coal Mines - ScienceDirect

2013-01-01  Spontaneous heating and fire in coal mines is a major problem worldwide and has been a great concern both for the industry and researchers in this field. Majority of fires existing today in different coalfields are mainly due to spontaneous combustion of coal. The auto oxidation of coal ultimately leads to spontaneous combustion which is the major root cause for the disastrous of coal mine in ...

Dust Explosions in Coal Mines and Industry

coal mine explosions occurred in the United States, resulting in more than 9300 fatalities. (A major explosion is one that causes five or more deaths.) The frequency of these disasters has decreased markedly in recent years. From 1902 to 1911, more than 100 major explosions occurred, whereas dur-ing each of the two recent decades less than 40 such disasters have occurred. The principal causes ...

Coal fires - Global Energy Monitor

Coal fires occur in operating coal mines, abandoned coal mines and waste coal piles. They sometimes start because of a nearby blaze, but they can also ignite through spontaneous combustion: certain minerals in the coal, such as sulfides and pyrites, can oxidize

Harmless Flour is an Incredibly Explosive Substance

2014-03-13  All it takes to cause a disaster is a suspended combustible powder and a little electric arc formed from electrostatic discharge, friction or even hot surfaces – A little spark is enough. Such settings are common in flour mills, where there is flour floating around literally everywhere.

FIRES, EXPLOSIONS, AND COMBUSTIBLE DUST HAZARDS

The major distinction between fires and explosions is the rate of energy release. Fires release energy slowly, whereas explosions release energy rapidly. Fires can also result from explosions, and explosions can result from fires. A good example of how the energy release rate affects the consequences of an accident is a standard automobile tire.

The presence of methane in underground mines adds to the risk of fire/explosion (methane ignition or spontaneous combustion). A build-up of methane gas was the stated cause of the tragic coal mine explosion in New Zealand in November 2010. The preferred method of underground fire-fighting is to flood the mine with water or inert gas.

Coal Mines in the Industrial Revolution - History Learning

Problems included flooding and the presence of explosive gases (called fire damp). A spark, which could easily come from a miner’s axe or a candle could spell disaster. Underground pit collapses were also common as the mines were only supported by wooden props. In 1841 about 216,000 people were employed in the mines in Britain. Most coal was mined in the north and the north-east as well as ...
