mining

Examples of mining in the following topics:

• Herbert Hoover: The Great Engineer

  • Originally, Hoover was a professional mining engineer and author.
  • In 1897, he went to Australia as an employee of Bewick, Moreing & Co., a London-based mining company.
  • After being appointed as mine manager at the age of 23, he led a major program of expansion for the Sons of Gwalia gold mine at Gwalia, Western Australia.
  • Hoover worked at gold mines in Big Bell, Cue, Leonora, Menzies and Coolgardie, Western Australia.
  • Hoover worked as chief engineer for the Chinese Bureau of Mines and as general manager for the Chinese Engineering and Mining Corporation.

• The Cripple Creek Miners' Strike of 1894

  • The influx of silver miners into the gold mines caused a lowering of wages.
  • In January 1894, Cripple Creek mine owners J.J.
  • On February 1, 1894, the mine owners began implementing the 10-hour day.
  • Portland, Pikes Peak, Gold Dollar, and a few smaller mines immediately agreed to the eight-hour day and remained open, but larger mines held out.
  • Mine owners still holding out for the 10-hour day soon attempted to reopen their mines.

• Mining on the Comstock Lode

  • Mining camps soon thrived in the vicinity, which became bustling centers of wealth.
  • The Comstock Lode is notable not just for the immense fortunes it generated and the large role those fortunes had in the growth of Nevada and San Francisco, but also for the advances in mining technology that it spurred.
  • The mines declined after 1874, and eventually ceased in 1922.
  • Other emigrants followed, camped on the canyon and went to work at mining.
  • The miners who discovered the mines and the investors who bought their claims did not know the size of the strike.

• Gold Fever in the West

  • San Francisco saw hastily erected housing—often docked ships whose crews had headed for the mines.
  • Without courts or law officers in the mining communities to enforce claims and justice, miners developed their own ad hoc legal system, based on the "mining codes" used in other mining communities abroad.
  • In a few years, nearly all of the independent miners were displaced as mines were purchased and run by mining companies, who then hired low-paid miners.
  • Bigger mines, however, caused greater environmental damage.
  • In the mountains, shaft mining predominated, producing large amounts of waste.

• Productivity Gains from Technology

  • Mining and metal refining technologies played a key role in technological progress.
  • Railroads evolved from mine carts and the first steam engines were designed specifically for pumping water from mines.

• The Molly Maguires

  • At the time, however, fears about the Molly Maguires enabled mine owners to destroy the miners' union, the Workingman's Benevolent Association.
  • During the mid 19th century, "hard coal" mining came to dominate northeastern Pennsylvania.
  • On September 6, 1869, a fire at the Avondale Mine in Luzerne County took the lives of 110 coal miners.
  • The families blamed the coal company for failing to finance a secondary exit for the mine.
  • In addition to the railroad, Gowen owned two-thirds of the coal mines in southeastern Pennsylvania.

• Hydrothermal Vent Microbial Ecosystems

  • Despite being some of the most remote ecosystems in the world, hydrothermal vents are under threat from mining companies.
  • As mineral resources on land have become depleted, mining companies have turned to deep sea geothermal vents to extract metals and sulfur.
  • Although the technology for deep sea mining is new, conservation biologists are concerned that mining hydrothermal vents will destroy these fragile and unique ecosystems.

• Types of Operations: Evolving from K, 1st, 2nd, and 3rd Grade

  • Mining Down: How can we utilize the standards to create what a realization for operations on number sets would be for a 3rd grader compared to the realizations possible from the first three grades?

• Types of Operations: Evolving operations through the K, 1st, 2nd, 3rd, 4th, & 5th Grade

  • Mining Down: How can we utilize the standards to create what a realization for operations on number sets would be for a 5th grader compared to the realization possible from the first 5 grades.

• Systems of Numbers: Evolving from Kindergarten to First Grade

  • Mining down: How can we utilize the standards to create what a realization for number would be for a first grader compared to a kindergartner?
