How long does a mine last?
For a copper mine, the extraction period or lifespan is generally expected to be somewhere between 5 to 70 years. Other mines, such as diamond mines or nickel mines, have a significantly shorter duration of extraction with some 27 and 22 years, respectively.
How do you start an open pit mine?
To create an open-pit mine, the miners must determine the information of the ore that is underground. This is done through drilling of probe holes in the ground, then plotting each hole location on a map. The information gained through the holes with provide an idea of the vertical extent of the ore’s body.
Is coal the cheapest source of energy?
Of all the fossil-fuel sources, coal is the least expensive for its energy content and is a major factor in the cost of electricity in the United States.

Why solar energy is bad?
New research shows, albeit unintentional, that generating electricity with solar panels can also be a very bad idea. In some cases, producing electricity by solar panels releases more greenhouse gases than producing electricity by gas or even coal.
