In March 1980, shortly after dredge mining commenced, a significant sandslide occurred displacing four hectares of vegetation. The slide completely reformed the coastline of the Island. Rather than attempt to rehabilitate the area, CRL created a boating recreation area for public use on the site.
intensive reclamation practices used to address shortterm erosion and water quality concerns affect longterm recovery. 2. In 1992–93 and 1999 the vegetation on 15 coal surface mines reclaimed between the years 1967–87, and five periodically logged hardwood forest reference sites in southwestern ia, were surveyed. 3.
First released in October 2000, the menu of BMPs is based on the stormwater Phase II rule''s six minimum control measures. EPA has found the practices listed in the menu of BMPs to be representative of the types of practices that can successfully achieve the minimum control measures. The BMP examples ...
Best Management Practices for Placer Mining in Yukon Wetlands 2 1. Introduction Placer mining has been a cornerstone of the Yukon''s economy and modern culture since the great Klondike Gold Rush of 1898. Currently there are over 100 family based placer mines with combined gross revenues in excess of 70 million annually.
Oct 03, 2012· Overburden materials (biproducts of coal processing) are often used to reclaim highwalls and valleyfill impoundments. These sites are a particular challenge to vegetate. The common practice for reclaiming these areas is to apply a minimum soil layer of 1824 inches as a "cap" on top of the overburden material prior to seeding.
tailings. The amount of tailings a mining operation produces far outweighs the amount of usable ore they get from the same site. For every 20 pounds of chalcopyrite, you might get only about five pounds of copper. The rest is just waste material, called the tailings. Tailings are a serious environmental problem.

Apr 29, 2014· 2. Scrap mining and recycling. On a global scale, mining corporations around the world are discovering efficient ways to capitalize fully on materials in order to provide the goods and services people want using much less wood, metal, stone, plastic and other materials.
Site planning should ensure that the area of land disturbed and vegetation cleared for mining operations is minimised. This will reduce environmental and visual impact and the area to be rehabilitated. Retained vegetation may also reduce the need for planting of buffers and visual screens and act as a source of seed for revegetation.
SELECTING MATERIALS FOR MINE SOIL CONSTRUCTION WHEN ESTABLISHING FORESTS ON APPALACHIAN MINE SITES Jeff Skousen, Carl Zipper, Jim Burger, Christopher Barton, and Patrick Angel The Forestry Reclamation Approach (FRA) is a method for reclaiming coalmined land to forest (FRA Advisory #2, Burger and others 2005). The FRA is based on
Dec 05, 2019· At Teck, we plan for responsible mine closure before mining begins. ... Reclamation at higher elevation sites can mean a harsher climate—higher winds, more exposed sites—so vegetation planted in these areas needs to be tailored to thrive in these conditions. A lot of work goes into determining the right types of vegetation to plan: site ...
excess material onsite will not only avoid transportation costs, but can aid in later reclamation. Onsite disposal, however, ... reduced by planting vegetation on top of the slope or cut, as certain types of vegetation ... attention to the geologic stability when planning reclamation and mining activities.
The life cycle of mining begins with exploration, continues through production, and ends with closure and postmining land use. New technologies can benefit the mining industry and consumers in all stages of this life cycle. This report does not include downstream processing, such as smelting of ...
Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef or placer deposits form a mineralized package that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay.
Mining is an inherently invasive process that can cause damage to a landscape in an area much larger than the mining site itself. The effects of this damage can continue years after a mine has shut down, including the addition to greenhouse gasses, death of flora and fauna, and erosion of land and habitat.
The reclamation sites range broadly in size: Deep mine sites are usually only 24 ac., whereas surface mining sites range from 20 to 1,200 ac. Planned postmining uses of the coalmining sites Massie works to reclaim include pastureland, woodland and wildlife areas, and more recently commercial forests.
Mining activity is causing environmental change in the landscape, particularly by changing the vegetation cover and affecting soil and water from the mine boundary region. 2 Furthermore, the mining activities require an additional area to be used for disposal of waste, and years of intensification affect the quality of surrounding soils and ...
Mine reclamation is the process of restoring land that has been mined to a natural or economically usable state. Although the process of mine reclamation occurs once mining is completed, the planning of mine reclamation activities occurs prior to a mine being permitted or started.
