Argonaut Mine
The Argonaut Mine is a gold mine in Jackson, California, United States. The deposit was discovered 1850 and was the site of the worst gold-mining disaster in the state's history. The mine closed in 1942 and, along with the nearby Kennedy Mine, is registered as California Historical Landmark #786. The gold deposit was discovered by two miners, James Hager and William Tudor. Serious development began in 1893 when it was purchased by the Argonaut Mining Company. The mine operated until 1942 reaching a vertical depth of via a 63-degree shaft and produced more than $25 million in gold. Disaster On August 27, 1922, 47 miners, mostly immigrants from Italy, Spain, and Serbia, were trapped in a fire below ground. Other miners who had been near the surface poured water down the shaft in an attempt to put out the flames. By dawn, townspeople and other miners arrived to help, but it took two-and-a-half days for the fire to be extinguished. Rescuers began re-opening tunnels from the ...

California State Route 49
State Route 49 (SR 49) is a north–south state highway in the U.S. state of California that passes through many historic mining communities of the 1849 California gold rush. Highway 49 is numbered after the "49ers", the waves of immigrants who swept into the area looking for gold, and it is known as the Golden Chain Highway. This roadway begins at Oakhurst, California, Oakhurst, Madera County, California, Madera County, in the Sierra Nevada (U.S.), Sierra Nevada, where it diverges from State Route 41.

Former Mines In The United States
A former is an object, such as a template, gauge or cutting die, which is used to form something such as a boat's hull. Typically, a former gives shape to a structure that may have complex curvature. A former may become an integral part of the finished structure, as in an aircraft fuselage, or it may be removable, being using in the construction process and then discarded or re-used. Aircraft formers Formers are used in the construction of aircraft fuselage, of which a typical fuselage has a series from the nose to the empennage, typically perpendicular to the longitudinal axis of the aircraft. The primary purpose of formers is to establish the shape of the fuselage and reduce the column length of stringers to prevent instability. Formers are typically attached to longerons, which support the skin of the aircraft. The "former-and-longeron" technique (also called stations and stringers) was adopted from boat construction, and was typical of light aircraft built until the ad ...

Disasters In California
A disaster is a serious problem occurring over a short or long period of time that causes widespread human, material, economic or environmental loss which exceeds the ability of the affected community or society to cope using its own resources. Disasters are routinely divided into either "Natural disaster, natural disasters" caused by Natural hazard, natural hazards or "human-instigated disasters" caused from Anthropogenic hazard, anthropogenic hazards. However, in modern times, the divide between natural, human-made and human-accelerated disasters is difficult to draw. Examples of natural hazards include avalanche, avalanches, Flood, flooding, cold wave, cold waves and heat wave, heat waves, drought, droughts, earthquake, earthquakes, Cyclone, cyclones, landslide, landslides, lightning, tsunami, tsunamis, Volcanism, volcanic activity, wildfire, wildfires, and Winter storm, winter precipitation. Examples of anthropogenic hazards include Crime, criminality, civil disorder, terr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mining Disasters In The United States
Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef, or placer deposit. The exploitation of these deposits for raw material is based on the economic viability of investing in the equipment, labor, and energy required to extract, refine and transport the materials found at the mine to manufacturers who can use the material. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay. Mining is required to obtain most materials that cannot be grown through agricultural processes, or feasibly created artificially in a laboratory or factory. Mining in a wider sense includes extraction of any non-renewable resource such as petroleum, natural gas, or even water. Modern mining processes involve prospecting for ore bodies, analysis of the profit potential of a proposed mine, extraction of the desired materials, and fi ...

Gold Mines In California
Gold is a chemical element with the symbol Au (from la, aurum) and atomic number 79. This makes it one of the higher atomic number elements that occur naturally. It is a bright, slightly orange-yellow, dense, soft, malleable, and ductile metal in a pure form. Chemically, gold is a transition metal and a group 11 element. It is one of the least reactive chemical elements and is solid under standard conditions. Gold often occurs in free elemental ( native state), as nuggets or grains, in rocks, veins, and alluvial deposits. It occurs in a solid solution series with the native element silver (as electrum), naturally alloyed with other metals like copper and palladium, and mineral inclusions such as within pyrite. Less commonly, it occurs in minerals as gold compounds, often with tellurium (gold tellurides). Gold is resistant to most acids, though it does dissolve in aqua regia (a mixture of nitric acid and hydrochloric acid), forming a soluble tetrachloroaurate anion. Gold i ...

Buildings And Structures In Amador County, California
A building, or edifice, is an enclosed structure with a roof and walls standing more or less permanently in one place, such as a house or factory (although there's also portable buildings). Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the term ''building'' compare the list of nonbuilding structures. Buildings serve several societal needs – primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical division of the human habitat (a place of comfort and safety) and the ''outside'' (a place that at times may be harsh and harmful). Ever since the first cave paintings, buildings have also become objects or canvasses of much artistic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Monongah Mining Disaster
The Monongah mining disaster of Monongah, West Virginia occurred on December 6, 1907, and has been described as "the worst mining disaster in American history." 362 miners were killed. The explosion occurred in Fairmont Coal Company’s No. 6 and No. 8 mines, and was one of the contributing events leading to the creation of the United States Bureau of Mines. The disaster On Friday, December 6, 1907, there were officially 420 men in the two mines, although the actual number was much higher as officially registered workers often took their children and other relatives into the mine to help. At 10:28 AM, an explosion occurred in one section of the mine, followed by a larger explosion in another area, instantly killing most of those inside. The blast caused considerable damage to both the mine and the surface. The ventilation systems, necessary to keep fresh air supplied to the mine, were destroyed, along with many railcars and other equipment. The entrance and ventilation fan of ...
