quarrying impacts encyclopedia mining and quarrying extract a wide range of useful materials from the ground such as coal, metals, and stone. these substances are used widely in building and manufacturing industry, while precious stones have long been used for adornment and decoration. 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. they have a direct impact on the countryside by leaving pits and heaps of waste material. the extraction processes can also contaminate air and water with sulfur dioxideand other pollutants, putting wildlife and local populations at risk. more careful use of natural resources, including recycling, and also restoration efforts after mining and quarrying can help limit these environmental impacts. see full list on encyclopedia people have always extracted useful materials from the ground. the stone, bronze, and iron ages were underpinned by knowledge of how to obtain these materials. archaeological studies have shown evidence for copper mining in africa around 6,000 s ago and, a little later, in ancient egypt and north america. meanwhile, the romans developed many mining techniques to make the process more efficient. today practically every manufactured item contains material that has been mined or quarried. mining involves taking an economically useful material from the ground. substances that are mined include ores, coal, evaporites, and precious stones and metals. quarrying is the cutting or digging of stone, and related

environmental impact. far fewer lives are claimed by the industry in modern times, thanks to improved technology and safety measures. however, mining was a difficult and dangerous job. valuable materials like g and diamonds have often helped finance corrupt regimes, crime, and terrorism while inhuman labor conditions have often been employed in their extraction. the environmental impacts of mining and quarrying are several. while the extractions are underway, the landscape is visibly disfigured and habitat loss can be extensive. the mining operations themselves and the accompanying spoil heaps cause a drastic change in the location with direct destruction of habitat and blocking or burying nearby bodies of water. mining can often affect local hydrology, causing changes in the water flow as well as quality. the pits left behind by large mining operations often fill with groundwater, which then see full list on encyclopedia acid rain:a form of precipitation that is significantly

exploited. this involves leveling spoil heaps, filling in holes and regrassing the area. however, it can take many s for vegetation to become reestablished at a former mine site. there are also many abandoned mines where environmental impact is ongoing. emissions from mining and quarrying can contaminate both air and water. the u.s. environmental protection agency (epa) lists as many as 100
