mining

The mining technique is shaky.

Eventually they found their way to the cities or mining communities and provided the human power upon which the Industrial Revolution was built.

In the case of the steel industry, this means the mining of iron ore, the transportation used to get ore from the mine to the mill, turning the ore into the steel, the manufacturing process and sales.

And soon afterwards, it supported one of the largest metal mining operations in America.

At one time, four mining companies employed 2500 workers in the Copper Basin.

Well, this mining operation turned the Copper Basin into a desert.

In the 1840s, when mining operations started, it was a dense green forest.

Copper mining had gone on there for more than 90 years!

It wasn’t the mining itself that caused such massive destruction.

Raising water and grinding corn were by no means the only uses of the waterpower mill, and during the following centuries, the application of waterpower kept pace with the developing technologies of mining, iron working, paper making, and the wool and cotton industries.

Only iron smelting and mining required marshaling a significant amount of capital (wealth invested to create more wealth).

The picture of Teotihuacán that emerges is a classic picture of positive feedback among obsidian mining and working, trade, population growth, irrigation, and religious tourism.

The companies building the canals to transport coal needed surveyors to help them find the coal deposits worth mining as well as to determine the best courses for the canals.

The engine eliminated water in the mines by driving efficient pumps, which made possible deeper and deeper mining.

So water ice could enable the creation of a self-sustaining moon base someday, a mining camp perhaps or a departure point for further space exploration.
