Coal is mined from coal mines. Liquids like oil can be pumped from wells, but solid chunks of coal cannot.
Flooding, lower mining levels needed to be pumped out.
The steam engine needs coal, the coal comes from the coal mine
Crude oil
People drill wells to reach fresh water.
Have it pumped out. Septic tanks need to be pumped out at least every 5 years to get rid of all the solid material.
Crude Oil.
Oil, coal, and gas. Oil is pumped out of the ground, coal is mined, and gas is also pumped

Most towns have water wells and water is pumped from these to a filter plant and then to homes.
Yes and no. Some wells require artificial lift, particularly in the later stages of their life. Many newly discovered wells have sufficient pressure to flow naturally. See: http://en.wikipedia.org/wiki/Artificial_lift
Absolutely, petroleum is a finite resource. There is only so much of it in the oil wells, and when it is all pumped out, there is no more.
No. There is absolutely no wells in Fiji. Water are either pumped out of the earth, clean and fresh or water from the treatment plant through the Pulic Works Department.
Most neighbourhoods in North America get their water pumped from deep wells and then processed. Actually, most people in North American cities get their water from reservoirs. Rural people usually have wells.
BP is drilling two relief wells. The wells are intended to intersect the blown out well. Heavy mud will be pumped down at least one of the relief well and will overcome the oil coming out. This will stop the spill. Cement will be pumped down the well so oil will never again flow out of the well.
It's simply a long pipe that is bored into the ground in order to reach an aquifer. The water is then pumped into a surface reservoir.
We use coal 4 oil. we get half of our oil from California wells. Over 50 % of the oil we use, in the entire US comes from the outdoors
Coal has only one advantage relative to oil, which is that it is abundant and relatively inexpensive. Disadvantages include, it is more polluting (due to impurities in the coal) and it is harder to handle; oil can be pumped, whereas coal has to be shoveled. Coal mining is often more difficult and dangerous than pumping oil out of the ground. Coal dust creates the dangers of explosion, and black lung disease.
