Mining and Quarrying. Mining has taken place in areas now scheduled for development. Whereas ground subsidence from modern mining is predictable in time and location, ground subsidence from older mining is unpredictable and may occur hundreds of years later, due to the pillar and stall method of roof support, where the pillars eventually decay and collapse.

Mining is a form of work that is dangerous to children in every way. It is physically dangerous because of the heavy and awkward loads, the strenuous work, the unstable underground structures, heavy tools and equipment, the toxic and often explosive chemicals, and the exposure to extremes of heat and cold.
Mining and quarrying involve investigating potential sites of extraction, then getting the required material out of the ground, and finally processing with heat or chemicals to get out the metal or other substance of interest. All these operations may use large amounts of water. Mining and quarrying can be very destructive to the environment.

1. What is Opencast Mining? : Opencast mining or quarrying of minerals is easier than mining by underground methods. During quarrying the alluvium and rocks below which the minerals lie, are removed and dumped, in the initial stages, in a place which is not required in future for quarrying, residential or other purposes.
Mine is a synonym of quarry. As nouns the difference between mine and quarry is that mine is an excavation from which ore or solid minerals are taken, especially one consisting of underground tunnels while quarry is a site for mining stone, limestone or slate or quarry can be an animal which is hunted, notably mammal or or quarry can be a diamond-shaped tile or pane, notably of glass or ...

Most limestone and dolomite are mined from open quarries, although in many areas economic and environmental considerations favor large-scale production by underground mining. The only carbonate materials not consistently recovered by surface or underground mining are shell products that are dredged from parts of U.S. coastal waterways.
