Naomi Mine Explosion
The Naomi Mine explosion occurred on December 1, 1907, in the Naomi Mine, approximately from Fayette City, Pennsylvania. The incident resulted in the deaths of at least 35 miners and left no survivors. Naomi Mine The Naomi Mine was operated by Hillman Coal and Coke Company. It was situated east of the Monongahela River. The mine was built to exploit the Pittsburgh coal seam, which was positioned at a depth of below the surface of the mine. Coal was hauled out of the mine with carts that were equipped with electric motors. From 1870 (the earliest year records were kept) to December 1, 1907 (the day the mine closed), a total of 63 men were killed in the Naomi Mine. Events and aftermath The explosion happened at about 7:15 on the night of Sunday, December 1, 1907. Inadequate ventilation allowed pockets of explosive gas to accumulate in the interior of the mine. The gas was most likely ignited by an open light or electric arc, both of which would have been present at the time. Seve ...

Monongahela River
The Monongahela River ( , )—often referred to locally as the Mon ()—is a U.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map accessed August 15, 2011 river on the Allegheny Plateau in North Central West Virginia, north-central West Virginia and Greater Pittsburgh, Southwestern Pennsylvania. The river flows from the confluence of its west and east forks in north-central West Virginia northeasterly into southwestern Pennsylvania, then northerly to Pittsburgh and its confluence with the Allegheny River to form the Ohio River. The river's entire length is navigable via a series of locks and dams. Etymology The Unami language, Unami word ''Monongahela'' means "falling banks", in reference to the geological instability of the river's banks. Moravian Church, Moravian missionary David Zeisberger (1721–1808) gave this account of the naming: "In the Lenape language, Indian tongue the name of this river was ''Mechmenawungihilla'' (alter ...

Pittsburgh Coal Seam
The Pittsburgh Coal Seam is the thickest and most extensive coal bed in the Appalachian Basin; hence, it is the most economically important coal bed in the eastern United States. The Upper Pennsylvanian Pittsburgh coal bed of the Monongahela Group is extensive and continuous, extending over 11,000 mi2 through 53 counties. It extends from Allegany County, Maryland to Belmont County, Ohio and from Allegheny County, Pennsylvania southwest to Putnam County, West Virginia. This coal seam is named for its outcrop high on the sheer north face of Mount Washington in Pittsburgh, Pennsylvania, and it is considered to form the base of the upper coal measures of the Allegheny Plateau, now known as the Monongahela Group. The first reference to the Pittsburgh coal bed, named by H.D. Rodgers of the First Geological Survey of Pennsylvania, was on a 1751 map. The section of the Pittsburgh seam under the Georges Creek Valley of Western Maryland is known as The Big Vein This is isolated f ...

Underground Mine Ventilation
Underground mine ventilation provides a flow of air to the underground workings of a mine of sufficient volume to dilute and remove dust and noxious gases (typically NOx, SO2, methane, CO2 and CO) and to regulate temperature. The source of these gases are equipment that runs on diesel engines, blasting with explosives, and the orebody itself. The largest component of the operating cost for mine ventilation is electricity to power the ventilation fans, which may account for one third of a typical underground mine's entire electrical power cost. Types of ventilation Flow-through ventilation is the main ventilation circuit for the mine. Air enters the mine from surface via a shaft, ventilation raise or adit. The air is distributed through the mine via internal ventilation raises and ramps, and flows are controlled by regulators and permanently mounted ventilation fans. An auxiliary ventilation system takes air from the flow-through system and distributes it to the mine w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electric Arc
An electric arc, or arc discharge, is an electrical breakdown of a gas that produces a prolonged electrical discharge. The electric current, current through a normally Electrical conductance, nonconductive medium such as air produces a plasma (physics), plasma; the plasma may produce visible light. An arc discharge is characterized by a lower voltage than a glow discharge and relies on thermionic emission of electrons from the electrodes supporting the arc. An archaic term is voltaic arc, as used in the phrase "voltaic arc lamp". Techniques for arc suppression can be used to reduce the duration or likelihood of arc formation. In the late 19th century, Arc lamp, electric arc lighting was in wide use for Street light#Arc lamps, public lighting. Some low-pressure electric arcs are used in many applications. For example, fluorescent lamp, fluorescent tubes, mercury, sodium, and metal-halide lamps are used for lighting; xenon arc lamps have been used for movie projectors. Electric a ...

Darr Mine Disaster
The Darr Mine disaster at Van Meter, Rostraver Township, Westmoreland County, Pennsylvania, Rostraver Township, Westmoreland County, Pennsylvania, near Smithton, Pennsylvania, Smithton, killed 239 men and boys on December 19, 1907. It ranks as the worst coal mining disaster in Pennsylvanian history. Many victims were of immigrants from central Europe, including Rusyns, Hungarians (including Slovaks from Gemer and Abov - then part of Austria-Hungary), Austrians, Germans, Polish people, Poles and Italians. The mine was operated by the Pittsburgh Coal Company. It was located on the west side of the Youghiogheny River and along the route of the Pittsburgh and Lake Erie Railroad. Most of the miners and other mine laborers lived in the nearby community of Jacobs Creek, Pennsylvania, Jacobs Creek and took a "sky ferry" (aerial tramway) across the Youghiogheny River to the mine entrance. Although some lived in nearby Van Meter. An inquiry carried out after the disaster determined tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Coal Mining Disasters In Pennsylvania
Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams. Coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years. Vast deposits of coal originate in former wetlands called coal forests that covered much of the Earth's tropical land areas during the late Carboniferous ( Pennsylvanian) and Permian times. Many significant coal deposits are younger than this and originate from the Mesozoic and Cenozoic eras. Coal is used primarily as a fuel. While coal has been known and used for thousands of years, its usage was limited until the Industrial Revolution. With the invention of the steam engine, coal consumption increased. In 2020, coal supplied about a quarter of the world's primary energy and over a third of its electricity. Some iron a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
