What Are the Advantages and Disadvantages of Surface Mining? Advantages of surface mining include economic and financial benefits for miners and communities and a safer alternative to pit mining, but its disadvantages include environmental impacts, such as erosion and contamination.
Oct 16, 2015· SURFACE MINING • Surface mining is done by removing (stripping) surface vegetation, dirt, and, if necessary, layers of bedrock in order to reach buried ore deposits (or) surface mining is the process of extraction of minerals by removal of overburden . • Overburden is the rock or waste material which is lying on the mineral to be owned .
Conventional Methods of Surface Mining. Open-pit mining and strip mining are the two major categories of surface mining which account for more than 90% worldwide surface mining production. The primary differences between these mining methods are the location of the ore body and the mode of mechanical extraction.

The Surface Mining Control and Reclamation Act is a law passed by the U.S. Congress in 1977 to regulate the environmental effects coal mining has in the United States. The law created a program to regulate active coal mines and another to rehabilitate abandoned mines. Before 1977, around 1.1 million coal mines had been abandoned around the country.
Surface Mining - Kalkstein in Russland ... The mining performance of the two 2200 SM – the smallest surface miners from the broad WIRTGEN product range ... One of the main advantages of surface mining over drilling and blasting is that the limestone can be loaded directly onto trucks by means of a powerful transfer system.
It is large enough for men and machinery to move about, is cost efficient and safe compared to open shaft mining. Cons: Leads to habitat loss, creates large holes in the ground and those holes allow water to drain into them where they could become acidic.
Strip mining is a form of resource collection that involves dirt removal from a very large area to sift through it. Instead of working underground, a pit is created deep in the ground and all work is accomplished on the surface. Here are the pros and cons of strip mining to consider. Mining …
Apr 02, 2018· Advantages and disadvantages of open pit mining. Open pit mining is profitable when the deposit is not very deep or when the terrain is sandy or delicate, so that underground mining is not possible. Labor costs are lower, both in excavation and transportation, and allow the use of …
Surface Mining Product Description Advantages Approvals/Specifications/ Recommendations RENOLIN XTREME TEMP AW – circulating and hydraulic oils with a high viscosity index, high shear stability and extremely
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.. Surface mining began in the mid-sixteenth century [dubious ...
Mar 13, 2018· Open pit mining does offer some advantages over traditional deep shaft mining. Pit mining is more cost effective than shaft mining because more ore can be extracted and more quickly. The working conditions are safer for the miners because there is no risk of cave in or toxic gas. Open pit mining is the preferred ...
Environmental Impacts Laws - Details about how the topsoil will be affected and how it will be replaced must be stated before mining begins. - All affected water must be processed and cleaned before leaving the mining site. - Procedures for public notice, public participation and
A Worldwide Name, World Class Performance. FUCHS Lubricants Co. has long been recognized within the mining industry as a leading innovator of lubricants designed for specialized applications in both underground and surface mining.
In the previous topic, we saw which are some of the advantages that can make the surface open pit mining methods superior method compared to the underground mining. However, underground mining has its own advantages. And finally, the ultimate decision to mine from the surface or from underground comes down to the specific characteristics of the deposit.
Feb 23, 2018· In surface mining, the ore is accessed directly from the Earth's surface, and contact is maintained with the surface throughout the operation. Underground or subsurface mining is accomplished with the help of tunnels going into the Earth, and does not occur on the surface…
