Federal Mines Safety Act Of 1910
Federal Mines Safety Act of 1910 was a United States statute passed for the purposes of establishing the United States Bureau of Mines as a federal agency of the United States Department of the Interior. The Act of Congress authorized investigations of mining methods with an emphasis regarding the safety of miners while recovering combustible fossil fuels and confronting occupational dust exposure. In 1897, the United States Geological Survey created a mining geology program providing geological studies of mining districts (e.g., Comstock Lode and Leadville mining district) and examinations relevant to efficient mining extraction technologies of fossil fuel and precious metal materials. The 1910 public law commissioned the United States Bureau of Mines to conduct future investigations of mining accidents exempting the United States Geological Survey. The H.R. 13915 bill was passed by the 61st United States Congressional session and enacted into law by the 27th president of ...

Mineral Lands And Mining
In geology and mineralogy, a mineral or mineral species is, broadly speaking, a solid chemical compound with a fairly well-defined chemical composition and a specific crystal structure that occurs naturally in pure form.John P. Rafferty, ed. (2011): Minerals'; p. 1. In the series ''Geology: Landforms, Minerals, and Rocks''. Rosen Publishing Group. The geological definition of mineral normally excludes compounds that occur only in living organisms. However, some minerals are often biogenic (such as calcite) or are organic compounds in the sense of chemistry (such as mellite). Moreover, living organisms often synthesize inorganic minerals (such as hydroxylapatite) that also occur in rocks. The concept of mineral is distinct from rock, which is any bulk solid geologic material that is relatively homogeneous at a large enough scale. A rock may consist of one type of mineral, or may be an aggregate of two or more different types of minerals, spacially segregated into dis ...

Experimental Mine, U
An experiment is a procedure carried out to support or refute a hypothesis, or determine the efficacy or likelihood of something previously untried. Experiments provide insight into cause-and-effect by demonstrating what outcome occurs when a particular factor is manipulated. Experiments vary greatly in goal and scale but always rely on repeatable procedure and logical analysis of the results. There also exist natural experimental studies. A child may carry out basic experiments to understand how things fall to the ground, while teams of scientists may take years of systematic investigation to advance their understanding of a phenomenon. Experiments and other types of hands-on activities are very important to student learning in the science classroom. Experiments can raise test scores and help a student become more engaged and interested in the material they are learning, especially when used over time. Experiments can vary from personal and informal natural comparisons ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

63rd United States Congress
The 63rd United States Congress was a meeting of the legislative branch of the United States federal government, composed of the United States Senate and the United States House of Representatives. It met in Washington, D.C. from March 4, 1913, to March 4, 1915, during the first two years of Woodrow Wilson's presidency. The apportionment of seats in the House of Representatives was based on the Thirteenth Census of the United States in 1910. The Democrats had greatly increased their majority in the House, and won control of the Senate, giving them full control of Congress for the first time since the 53rd Congress in 1893. With Woodrow Wilson being sworn in as President on March 4, 1913, this gave the Democrats an overall federal government trifecta - also for the first time since the 53rd Congress. Major events *March 4, 1913: Woodrow Wilson became President of the United States. *March 9, 1914: The Senate adopted a rule forbidding smoking on the floor of the Senate becau ...

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 ...

Cross Mountain Mine Disaster
The Cross Mountain Mine disaster was a coal mine explosion that occurred on December 9, 1911, near the community of Briceville, Tennessee, in the southeastern United States. In spite of a well-organized rescue effort led by the newly created Bureau of Mines, 84 miners died as a result of the explosion. The likely cause of the explosion was the ignition of dust and gas released by a roof fall. At least 22 of the miners killed in the Cross Mountain Mine disaster were buried in a circular memorial known as the Cross Mountain Miners' Circle, which is now listed on the National Register of Historic Places. Geographical setting Cross Mountain is a massive ridge situated along the eastern Cumberland Plateau just west of the plateau's Walden Ridge escarpment, in the coal-rich Cumberland Mountains. Rising to an elevation of , the mountain is the highest point in Tennessee west of the Blue Ridge Province. The mountain is located along the border between Anderson County and Ca ...

Harwick Mine Disaster
The Harwick Mine disaster was a mining accident on January 25, 1904 in Cheswick, Pennsylvania, some north of Pittsburgh in the western part of the state. The blast killed an estimated 179 miners and 2 aid workers. The disaster ranks among the ten worst coal mining disasters in American history. One community especially impacted was the Hungarian community in Homestead, Pennsylvania. Fifty-eight of the members of the First Hungarian Reformed Church of Homestead—a full third of the congregation—died in the explosion. Coal was mined by compressed-air machine, blasted down with dynamite. Ice accumulation in the air shaft restricted ventilation which caused a buildup of methane gas. At 8:15am, workers blasted down dynamite which ignited the methane. Coal dust suspended in the air assisted the explosion in traveling throughout every region of the mine. In addition to interior devastation, the force was so powerful that it wrecked the exterior of the shaft. Of 175 mine workers ...

Banner Mine Disaster
The Banner mine disaster of April 8, 1911 near Littleton, Alabama was a coal mine explosion that killed 128 people. The event ranks among the 15 deadliest coal mine disasters in U.S. history. The exact cause of the early-morning blast is unknown. It is likely that an accidental spark ignited gas in the air, which directly killed seven men and knocked out a ventilation fan. Without the fan, levels of blackdamp rose in the mine. Another 121 miners suffocated. About 40 other workers were able to dig their way through rubble and escape. The Banner Mine was run by Pratt Consolidated Coal Company, then owned by Tennessee Coal & Iron. Seventy-two of the casualties were black convicts leased from the state and from Jefferson County. The explosion brought enough attention to horrific mine conditions for new governor Emmet O'Neal Emmet O'Neal (September 23, 1853 – September 7, 1922) was an American Democratic politician and lawyer who was the 34th Governor of Alabama fro ...
