Temporal trends in erosion and hydrology for a postmining landform at Ranger Mine DR Moliere, KG Evans amp; GR Willgoose1 Background An important part of rehabilitation planning for mines is the design of a stable landform for waste rock dumps or spoil piles, at the completion of mining, which minimise erosion and environmental impact offsite.
Jul 27, 2014#0183;#32;But West Point is slowly eroding away, being retaken by the relentless process of erosion, and like other communities along Liberia''s coastline, it is often because of the practice of sand mining
Aug 16, 2016#0183;#32;If you remove forest or green cover for mining, erosion will increase If you cut down trees, bushes, etc. to mine the area (as strip mining), the open area will be subject to erosion. Furthermore, the useless material that will be left without any cover will be subject to wind or water type erosion.
Mining causes erosion when it strips an area of vegetation, such as trees and plants. The roots of trees and plants are essential to keeping soil in... See full answer below.
In tropical countries soil erosion is often increased due to high erodibility of geologically old and weathered soils; intensive rainfall; inappropriate soil management; removal of forest vegetation cover; and mining activities. Stream ecosystems draining agricultural or mining areas are often severely impacted by the high loads of eroded material entering the stream channel; increasing
Mining Erosion Control and Protection Solutions Landfill Mining Erosion Surface mining removes or strips surface vegetation, dirt and layers of bedrock in order to reach buried ore deposits (normally gold, silver and copper). There are various types of surface mining, such as openpit mining, quarrying, strip mining
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.
Soil erosion caused by human land use is a widely known and intensively studied subject in agronomic sciences [] and biogeochemistry [].The mobilisation and the transport of soil particles primarily causes losses of the fine and less dense particle fractions, including humus particles and clay, both of which are important carriers of soil nutrients and stabilizing agents for the physical

Mar 14, 2017#0183;#32;Fine soil can be easily carried far away by the wind whereas the coarse heavier soil can only be dislodged for short distances. Areas with the finer soil are at a higher risk of intense soil erosion than those with coarse types. 10. Other human activities like quarrying and mining. Such activities expose land to uncontrolled surface drainage
Landfill Mining Erosion. Surface mining removes or strips surface vegetation, dirt and layers of bedrock in order to reach buried ore deposits (normally gold, silver and copper). There are various types of surface mining, such as openpit mining, quarrying, strip mining and mountaintop removal. This process typically involves taking the top of a mountain off to reach ore deposits at depth.
Although soil erosion is a natural process, human activities have greatly accelerated it. The agents of soil erosion are the same as of other types of erosion: water, ice, wind, and gravity. Soil erosion is more likely where the ground has been disturbed by agriculture, grazing animals, logging, mining, construction, and recreational activities
Mar 14, 2017#0183;#32;Mining is one of the main causes of environmental impact of mining includes soil erosion, formation of sinkholes, loss of biodiversity, and contamination of soil, groundwater and surface water by chemicals from mining processes. Mining occurs so as to extract precious metals and gemstones such as Manganese, tantalum, cassiterite, copper, tin, nickel, bauxite (aluminum
Open Pit Mining. Open pit mining is similar to area mining. The technique is common in the western United States (and other parts of the world) where very thick 50 to 100 foot coal seams exist. Open pit mines are usually large operations. Production levels may exceed 10 million tons of coal per year.. The thick coal seams found at these large mines ensure that the amount of land
Mining activity changes the landuse pattern and alters the surface topography by increased surface erosion and excavations. If proper reclamation is not done, this can result in unaesthetic landscape. Openpit mines must be filled with mine waste rock as reclaimed land. It can be filled with rain or floodwater for fisheries, water sports etc. (F)

There are different practices and different regulations and laws for mining in different countries.
Jan 23, 2017#0183;#32;4. Erosion and Sedimentation Mineral development disturbs soil and rock in the course of constructing and maintaining roads, open pits, and waste impoundments. In the absence of adequate prevention and control strategies, erosion of the exposed earth may carry substantial amounts of sediment into streams, rivers and lakes.
Sep 05, 2014#0183;#32;When geological erosion takes place, there is enough time for natural reclamation of the land to occur, because the soil of the land is usually being eroded at roughly the same rate as the new soil is being formed. The easiest example of natural erosion and reclamation is a river path. Geological erosion due to the moving water of the river
This land disturbance is on a vast scale. In the US, between 1930 and 2000, coal mining altered about million hectares [ million acres] of natural landscape, most of it originally forest. Attempts to reseed land destroyed by coal mining is difficult because the mining process has so thoroughly damaged the soil.
Erosion of exposed hillsides, mine dumps, tailings dams and resultant siltation of drainages, creeks and rivers can significantly impact the surrounding areas.
