impacts from quarrying activities on the health of the people are quite significant as blasting vibrations have also resulted in cracks in several buildings exposing the occupants to danger. Other potential quarrying effects which are of concern to environmentalists include biodi versity loss, land degradation, nuisance effects, reduced
Apart from land degradation, other negative impacts of quarrying includes swamp creation, deterioration of ground water, erosion of soil, noise and percussions from rock blasting, generation of dust, smoke and fumes; production of noxious gases and ground vibration.
quarrying are managed in an integrated and structured manner that boosts institutions in quarrying perform . One of the biggest negative impacts of quarrying on the environment is the damage to biodiversity . Quarrying carries the potential of destroying habitats and the species they support .
Several serious environmental impacts related to quarrying activities on and near the river such as vibra tions, land degradation, land subsidence and landslides, water pollution, occupational ...
T he most obvious engineering impact of quarrying is a change in geomorphology and conversion of land use, with the associated change in visual scene. This major impact may be accompa nied by loss of habitat, noise, dust, vibrations, chemical spills, erosion, sedimentation, and dereliction of the mined site.
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.

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 years 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 materials, from an excavation site or pit and it usually leaves behind a large hole in the ground. An ore is a deposit containing an economically viable amount of a mineral, which itself is a crystalline inorganic compound, usually containing a metal. It is the metal that is of val...
Mining and quarrying have often been criticized for their social and 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 gold 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
ACID RAIN:A form of precipitation that is significantly more acidic than neutral water, often produced as the result of industrial processes. EVAPORITES:Salts deposited by the evaporation of aqueous solutions. ORE:Rock containing a significant amount of minerals. STRIP MINING:A method for removing coal from seams located near Earths surface. becomes polluted. Mining companies now acknowledge that they need to invest in restoring land they have exploited. This involves leveling spoil heaps, filling in holes and re grassing the area. However, it can take many years for vegetation to become re established 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 lists as many as 100 different air pollutants issuing from the nations mining industry, including dust particles and sulfur dioxide, which can create acid precipitation...
