vicinity of sand-mining operations. We hope it will join the other Policy Studies in this series as a resource for understanding the concerns, potential impacts, and benefits associated with industrial sand mining. The "social" impact of sand-mining operations, including their impact on land use and property values, can be a sensitive topic.
In addition to silica dust and RCS, the transportation of sand may raise other concerns among residents of communities near sand mining operations. New mines are likely to increase truck and rail traffic, and may increase diesel emissions, noise, road congestion and accidents, and road maintenance needs.
Silica sand (also commonly referred to as frac sand) is a crucial ingredient in the oil and natural gas extraction process known as fracking. The hydraulic fracturing ("fracking") process for oil and gas takes a mixture of proppant (usually frac sand), water, and chemicals and injects this mixture into a well under very high pressure.
Silica is a well-known occupational hazard and has also been recently examined for its environmental concentrations near silica sand mines and transport terminals. Health Effects Disease risk is related to both the levels and duration of crystalline silica exposure.
article will use the more diplomatic and scientific term "silica sand." Frac sand is a specific type of silica sand, and most of the health and environmental issues associated with silica "frac" sand mining operations are of equal concern for all types of silica sand mining. See generally Silica Sand Mining in Wisconsin, WIS. DEP'T OF ...
Silica is actually a common naturally occurring element found in sand and quartz. When silica-containing rocks and minerals are blasted, chipped, cut, ground, and drilled, small particles are released into the air, which can then be breathed in and land in workers' lungs.
Overview. The DNR is committed to work with citizens to conserve and manage the state's natural resources. Over the past several years, there has been concern about the human health and environmental impacts of silica sand mining, processing, and transportation in Minnesota.
The sand, tumbled over and over along that shore, resulted in quartz of "incredible spherocity and hardness" that makes this area in the frac sand mining boom, the website states. Silica sand mining, however, produces a dangerous by-product: silica dust. Prolonged exposure to the tiny mineral particles can scar lung tissue resulting in ...
