It is very cost effective. Since cyanide, mercury and sulfuric acid are used to remove the wastewater, groundwater and air are contaminated as toxic … Surface mining has several benefits compared to underground mining, coal retrieval is high 85% to 90%, contrast to 40% to 70% in underground mines. For those who are unfamiliar, strip mining is a form of surface mining that focuses on the collection of tar sand and coal, which both rest somewhat close to Earth’s surface. 2. Those who support strip mining point to the increased ease of access and all of its attendant benefits. 1. This section reviews surface mining methods and practices. Here are the pros and cons of strip mining to consider. Coal mining operations have been proven out to be very damaging to the local environment and ecosystems, and strip mining scars will be seen on this planet for decades and decades to come. Strip mining is a form of resource collection that involves dirt removal from a very large area to sift through it. When the deposit is exhausted, the overburden is refilled in the crater, and the land is restored with the local vegetation. What are the advantages and disadvantages of surface mining? Detractors point to the controversies surrounding this method. This creates costs as well as environmental issues with waste rock disposal; Major disruption of surface: pit footprint, waste dumps. advantages and disadvantages of surface mining equipment. 3. The use of heavy machinery and blasting techniques also create environmental pollution. 1.1. High visual impact, especially strip mining. Surface mining, including strip mining, open-pit mining and mountaintop removal mining, is a broad category of mining in which soil and rock overlying the mineral deposit (the overburden) are removed, in contrast to underground mining, in which the overlying rock is left in place, and the mineral is removed through shafts or tunnels.. Classification of Surface Mining Methods Extraction of mineral or energy resources by operations exclusively involving personnel working on the surface without provision of manned underground operations is referred to as surface mining. Yet, it is a highly destructive form of surface mining is destructive to an entire region, the coalfield areas of West Virginia, Kentucky, Tennessee, and Virginia, for one reason only: profit. The disadvantages of surface mining are: That it destroys the landscape and environment;View more. List of Cons of Coal Mining. Open Pit Mining Pros & Cons. In all methods of surface mining, first, the overburden is stripped off using earthmovers.Then, bucket-wheel excavators remove the ore, which is loaded into haul trucks with shovel loaders. 4. Read more. Disadvantages of open pit mining. One of the main disadvantages of this type of mining operation is the environmental impact it causes. Strip Mining Pros to Consider . Open Pit Mining Pros & Cons | eHow. Instead of working underground, a pit is created deep in the ground and all work is accomplished on the surface. Surface mining has several benefits compared to underground mining, coal retrieval is high 85% to 90%, contrast to 40% to 70% in underground mines. Read more. Disadvantages of open pit mining. Opencast mining, also known as surface mining or strip mining, has disadvantages that include disturbance of the environment and local ecosystems, exposure of radioactive elements and contamination of freshwater sources. Heat from the coal produced in these mines contributes directly to greenhouse gasses responsible for global warming. Disadvantages of open pit mining. The disadvantages of surface mining are: That it destroys the landscape and environment;View more. advantages and disadvantages of open pit mining lorecentral. However, disadvantages when compared to Underground Mining also exist: Very large amounts of waste rock are mined. One of the maindisadvantagesof this type ofminingoperation is the environmental impact it causes. Open pit mining -- or strip mining -- is an extraction process for ore or fossil fuels that takes place at the surface of a mining site. 1.
