what was mined and why was it mined(1859-1889)?

Question

In the U.S.

Answer 1

COAL

Anthracite (or "hard" coal), clean and smokeless, became the preferred fuel in cities, replacing wood by about 1850. Anthracite from the Northeastern Pennsylvania Coal Region (and later from West Virginia) was typically used for household uses because it is a high quality coal with few impurities and stoves and furnaces were designed for it. The rich Pennsylvania anthracite fields were close to the Eastern cities, and a few major railroads like the Reading Railroad controlled the anthracite fields. By 1840, hard coal output had passed the million-short ton mark, and then quadrupled by 1850.

Bituminous (or "soft coal") mining came later. In the mid-century Pittsburgh was the principal market. After 1850 soft coal, which is cheaper but dirtier, came into demand for railway locomotives and stationary steam engines, and was used to make coke for steel after 1870. [12]

Total coal output soared until 1918; before 1890, it doubled every ten years, going from 8.4 million short tons in 1850 to 40 million in 1870, 270 million in 1900, and peaking at 680 million short tons in 1918. New soft coal fields opened in Ohio, Indiana and Illinois, as well as West Virginia, Kentucky and Alabama. The Great Depression of the 1930s lowered the demand to 360 million short tons in 1932.
