Mining and processing ore can have considerable impact on the environment. Surface mines can create enormous pits (see Figure Open Pit Mine) in the ground as well as large piles of overburden and tailings that need to be reclaimed, i.e., restored to a useful landscape. Since 1977 surface mines in U.S. are required to be reclaimed, and commonly ...

Like many other large equipment used in industrial and construction settings, stone crushing plants are also bound by environmental policies. Emerging economies have seen …
upon the karst environment. Much of the concern is motivated by the adverse envi-ronmental impacts of previous human activities in karst areas and the effects that those impacts have had on the quality of life. Many human activities can negatively impact karst areas, includ-ing deforestation, agricultural practices,
Methods used in Crushing & Screening Plants on ore range from a simple combination of a grizzly and one crusher to an elaborate arrangement in series of grizzly, jaw crusher, screens, and rolls or cone crushers.. Crushing is done underground at a few large mines. In general, the jaw crusher is the most suitable primary machine, yet many gyratories …
The mining industry is a fundamental source for building infrastructures and an enabler for a country's growth. Over the last decade, the act of mining has been among the top in the list of human activities which has the most disturbing and catastrophic impacts on environment, therein extensively affecting the ecological, economic, and social elements in …
China is the largest producer and consumer of coal in the world. The extraction of coal is increasing intensively to meet the needs of the ever-increasing population and industries. However, coal mining has resulted in environmental changes, including deforestation, air, water, soil, and landform deterioration. This study investigates the impact of mining on the …
The present study focused on environmental impact assessment (EIA) due to aggregate quarrying and crushing activities at four selected mining/crusher clusters in the middle catchment of Dwarka river basin of Eastern India. EIA is done both spatially and cluster wise considering the impacts of 10 number of influencing factors on 12 number of …
