Burlington And Northwestern Railway
The Burlington and Northwestern Railway (B&NW) was a narrow gauge railroad system in Iowa that operated during the late nineteenth and early twentieth centuries. It connected Burlington, Iowa with branches to Washington and Oskaloosa, Iowa. Incorporated in 1875 as the Burlington and Northwestern Narrow Gauge Railway Company, it began carrying traffic in 1876, when it also dropped 'narrow gauge' from its corporate name. The line reached Washington in 1880, operating over of track. In 1881, the Burlington and Western Railway Company, a subsidiary of the Chicago, Burlington and Quincy Railroad (CB&Q) was formed to connect the line to Oskaloosa, completed in 1883. For two decades, both lines were operated as a single system, until on June 20, 1902, the system was widened to standard gauge and the B&NW was adsorbed by the B&W. Later that year, the system was leased to the CB&Q, and in 1903, the entire system was deeded to the CB&Q. The B&NW-B&W system was one of only two narrow ...

White Americans (sometimes also called Caucasian Americans) are Americans who identify as white people. In a more official sense, the United States Census Bureau, which collects demographic data on Americans, defines "white" as "[a] person having origins in any of the original peoples of Europe, the Middle East, or North Africa". This group constitutes the majority of the people in the United States, although their proportion of the overall population has been White demographic decline, gradually declining. As of the latest American Community Survey in 2023, the US Census Bureau estimates that 60.5% of the US population, or 202,651,650 people, are White alone, while Non-Hispanic whites, Non-Hispanic Whites make up 57.1% of the population. Overall, 72.3% of Americans identify as White alone or in combination. European Americans are by far the largest panethnic group of white Americans and have constituted the majority population of the United States since the nation's founding. M ...

Population Density
Population density (in agriculture: Standing stock (other), standing stock or plant density) is a measurement of population per unit land area. It is mostly applied to humans, but sometimes to other living organisms too. It is a key geographical term.Matt RosenberPopulation Density Geography.about.com. March 2, 2011. Retrieved on December 10, 2011. Biological population densities Population density is population divided by total land area, sometimes including seas and oceans, as appropriate. Low densities may cause an extinction vortex and further reduce fertility. This is called the Allee effect after the scientist who identified it. Examples of the causes of reduced fertility in low population densities are: * Increased problems with locating sexual mates * Increased inbreeding Human densities Population density is the number of people per unit of area, usually transcribed as "per square kilometre" or square mile, and which may include or exclude, for example, ar ...

Room And Pillar
Room and pillar or pillar and stall is a variant of breast stoping. It is a mining system in which the mined material is extracted across a horizontal plane, creating horizontal arrays of rooms and pillars. To do this, "rooms" of ore are dug out while "pillars" of untouched material are left to support the roof – overburden. Calculating the size, shape, and position of pillars is a complicated procedure, and an area of active research. The technique is usually used for relatively flat-lying deposits, such as those that follow a particular stratum. Room and pillar mining can be advantageous because it reduces the risk of surface subsidence compared to other underground mining techniques. It is also advantageous because it can be mechanized, and is relatively simple. However, because significant portions of ore may have to be left behind, recovery and profits can be low. Room and pillar mining was one of the earliest methods used, although with significantly more manpower. The room ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shaft Mining
Shaft mining or shaft sinking is the action of excavating a mine shaft from the top down, where there is initially no access to the bottom. Shaft (civil engineering), Shallow shafts, typically sunk for civil engineering projects, differ greatly in execution method from deep shafts, typically sunk for mining projects. Shaft sinking is one of the most difficult of all mining development methods: restricted space, gravity, groundwater and specialized procedures make the task quite formidable. Shafts may be sunk by conventional drill and blast or mechanised means. Historically, mine shaft sinking has been among the most dangerous of all the mining occupations and the preserve of mining contractors called sinker (mining), sinkers. Today shaft sinking contractors are concentrated in Canada, Germany, China and South Africa. The modern shaft sinking industry is gradually shifting further towards greater mechanisation. Recent innovations in the form of full-face shaft boring (akin to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
