what happens to the quarries once mining has finished?

Answer 1

Usually it just sits there and gathers rain water, then it might leach out toxic chemicals and spills over to the surround area.
Some time they turn it into a waste dump. Sometimes they might build something useful like a stadium. It was proposed in Irwindale for a future sight for a football team in Los Angeles. On occasion, the government force the mining company to fill it with dirt and plant treas and might even build housing on top.
LIke I said, most of the time, it is left as an open sore on the face of the Earth.

Answer 2

In the UK quarries for things like stone have traditionally just been left as holes in the ground, or a flat area in front of a cliff face, depending on the size of the quarry. New quarries, and in particular, 'quarries' for coal - open casting - will only receive planning permission if the quarry owner agrees to 'reinstate' the area back to agricultural use after extraction has finished. This will be a condition of the permission allowing the quarrying, enforceable at law.

Answer 3

Over here in my country..we have many quarries with some as big over 100 acres. These quarries usually owned by the government in which they will order the mining pool to be emptied and filled it up with sand and some earth (after the mining pools are closed). After that this place will be left stand alone for 5 years for stability and will be developed into a town with houses/shops/school or hospitals.

Answer 4

With respect, you should look up the shopping centres of "Lakeside" in Essex and "Bluewater" in Kent to see what CAN be done with quarries when they are worked out. The 'history' of either or both is absolutely fascinating. Google the terms and also "Blue Circle" which company owned the original [chalk] quarries.

Also check "The Eden Project" in Cornwall which seems to have been built in a quarry and "Grangewaters" in Essex which is an outdoor pursuits centre in a former gravel pit.

Answer 5

They just make it part of the landscape
