Open pit mining is a widely used mining technique developed centuries ago, and it is difficult to credit a specific individual with its invention. However, open pit mining has been practiced throughout history in various forms, with the ancient Romans known to have used similar methods for extracting minerals. The technique has evolved and is now a prevalent method in modern mining operations.

The idea of open pit mining has been utilized throughout centuries by various civilizations. However, it is difficult to attribute its introduction to a single individual. Ancient cultures such as the Romans, Egyptians, and Greeks all practiced open pit mining in different forms for mining minerals and ores.
well the water mine was invented during the civil war
you people don't understand what we are saying i want the name of the people who invented the mines
An open-pit mine can be reclaimed. There are some serious issues to be dealt with, and some big bucks can be spent on them, but it can be done. And in many (if not most) instances, some form of reclamation is mandated by the governments of the states (or countries) where open-pit mines are operated.In open-pit mining, the mining is essentially done by digging a big hole in the ground. Any overburden is set aside, and the material sought is removed and transported away. Overburden (material that is "on top" of ore) or other dirt and earth can be used to cover abandoned mines. The large pit remains, but can be "landscaped" to restore the "look" and the "natural" earthen cover that was in place before the mining began.Once proper covering and shaping are done and the "surface" of the land is restored, about all a company has to do is deal with water runoff or groundwater penetration issues and they can walk away. There are issues with tailings and the other "left-overs" from any processing of mined material, and these are generally sorted out by geologists and geochemists. As long as any chemical treatments of materials is conducted properly, the tailings and other by-products can be covered over with "natural" material to complete the restoration.None of the issues associated with recovering (reclaiming) an open-pit mine are easy to address. Additionally, anything we do or demand be done comes with a price tag. But with some "signed agreements" in place and a bit of oversight by bright, reasonable people who can direct the mine operator to "do right" before closing a mine down, a "good" result can be obtained. A number of open-pit operations have been closed down around the world after exhausting rich ore or material bodies, and we've seen a "clean" environmental impact report following those mine closings and remedial activities.

Yes. Ancient man began doing it and open pit mining continues today.
no.
Uranium mining can be either by open pit mining or by underground mining.
Strip Mining.
Open pit mining is used when the materials being mined are closer to the surface. It is safer to do open pit mining than it is to do underground mining. Underground mining is only used for mining hard minerals.
1.Depth:strip mining is done for <60 m while open pit is done for>60 to near about 120 m. 2.Design:Strip mining is done maintaining spoil & piles system while open pit has a specific mining structure to follow. 3.Environment:strip mining is normally done for dry area while for open pit mining we have to lower the ground water level.
