The environmental impact of mining includes erosion in the environment, formation of sinkholes, loss of biodiversity, and contamination of soil, groundwater, and surface water
Soil erosion reduces cropland productivity and contributes to the pollution of adjacent watercourses, wetlands and lakes. Soil erosion can be a slow process that continues relatively unnoticed or can occur at an alarming rate, causing serious loss of topsoil.
The dredge industry refers to beach dredging as nourishment or renourishment, which implies that offshore sand mining and conveyance to beaches offers natural, unalloyed benefits to the coastal system. Aside from being expensive and short lived, however, beach dredging comes with a long list of environmental side effects.
2 Coastal Erosion Its Causes, Effects, and Distribution INTRODUCTION This chapter discusses how beaches are formed and factors that determine coastal erosion, stability, or accretion. It also contains a summary of U.S. coastline characteristics, which serves to empha size the diversity of shore types that must be considered in erosion management policies.

Mar 13, 20120183;32;The major impact of mining on the environment is mainly due to the physical damage of the landscape and the production of large volume of harmful wastes. In general, only a small fraction of the ore is valuable, the remaining large part is
Erosion is a process that causes the soil surface to wear out; geological erosion is caused naturally by water, wind or gravity, and accelerated erosion is caused by human use of land. Geologists estimate that 70 percent of soil erosion is caused by human activities like excessive construction, agriculture, surface mining and forestry.
Activities like drilling, mining, construction, broken water or drain pipes, improperly compacted soil after excavation work or even heavy traffic can result in small to large sinkholes. Water from broken pipe can penetrate through mud and rocks and erode the ground underneath and cause sinkholes.
Open cut mining is the most economical means of mining; it removes the minerals closest to the surface which are easiest to extract, but also exposes the largest area of the underlying soil to erosion.
Mining can create some environmental challenges, including mining erosion, sinkholes, soil contamination, and surface water contamination by chemicals from mining processes. Furthermore, there can be several high flow drainage channels that need to
Generally, soil erosion is the relocation of the top soil layer from its original location. It leaves the affected area exposed to more sporadic erosion making it a sequential occurrence. Below are some of the main causes of soil erosion. 1.
Surface mining (another name for quot;strip miningquot;) can severely erode the soil or reduce its fertility; pollute waters or drain underground water reserves; scar or altar the landscape; damage roads, homes, and other structures; and destroy wildlife. The dust and particles from mining roads, stockpiles, and lands disturbed by mining are a significant source of air pollution.

Soil erosion is, at its core, a natural process. Put simply, it is when topsoil, which is the upper most layer of the ground, is moved from one spot to another. Why this matters is because topsoil is the part of the land that is highest in organic matter and best suited for farming and other fertile
Causes of Soil Erosion Land use Humans play a major role in soil erosion through their use and abuse of natural resources, for example deforestation, grazing, arable land use, faulty farming systems, high crop intensity, housing construction, mining etc.
Sand mining and beach erosion are issues of great concern in countries such as St. Kitts and Nevis, Saint Lucia, and St. Vincent and the Grenadines among others (UNEP 1999). Growing coastal populations and the growth of coastal tourism in the Wider Caribbean Region are two additional factors contributing to increased sedimentation.
However, beach erosion is a growing cause for concern. And Sile Bay's sand dunes were destroyed as a result of sand mining for construction material. But this does not mean that we can rest easy for the next 35 years. an increased amount of eroded soil washes onto
Underground coal mining impacts. Although seen as less destructive than strip mining, underground mining still causes widespread damage to the environment. Subsidence. Collapse of earth into underground mines, or subsidence, is a serious problem.
These principles apply to both mining and con struction and form the framework upon which the erosion and sediment control strategy for a particular mining operation is built. Preplanning This principle stresses the need to plan the mining operation to minimize short term and
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 affects the environment by exposing radioactive elements, removing topsoil, increasing the risk of contamination of nearby ground and surface water sources, and
Extensive sand mining in some rivers has lead to the collapse of river banks, destabilising structures such as bridges and causing influx of salt water. Landslides and coastal erosion are other factors that have had a negative impact on the environment in Sri Lanka.
Aside from desertification, there is no doubt that human activities are a major cause of soil erosion in general. Construction of roads and buildings, logging, mining, and agricultural production have resulted in large amounts of soil erosion in the U.S. and around the world.
