Surface mining, including strip mining, openpit 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 mid16th century dubiousGet Price
These surface mining methods are considered to be more efficient and economical in extracting minerals as compared to most methods of underground mining. In fact, it can extract almost 90 of ore from a deposit. For this reason, surface mining is the most widely used method in North America.
The environmental damage caused by surface mining is related to the large amount of surface material that humans remove during mining operations. The environmental effects of surface mining include Habitat destruction Soil erosion Air pollution from dust particulates Pollution especially from sediments All surface mining techniques negatively affect the environment, though some methods are

The Surface Mining Control and Reclamation Act of 1977 SMCRA is the primary federal law that regulates the environmental effects of coal mining in the United States.. SMCRA created two programs one for regulating active coal mines and a second for reclaiming abandoned mine lands. SMCRA also created the Office of Surface Mining, an agency within the Department of the Interior, to promulgate

Surface mining is a form of mining in which the soil and the rock covering the mineral deposits are removed. It is the other way of underground mining, in which the overlying rock is left behind, and the required mineral deposits are removed through shafts or tunnels.. Surface mining is basically employed when deposits of commercially viable minerals or rock are found closer to the surface
There is a lots of difference between surface mining and subsurface mining,here i am starting with the basic definition below SURFACE MININGWhen the ore or mineral is present on near surface or shallow depth then excavation is carried out on th
MSHA Safety Training Requirements at a Surface Mine. The Mining Safety and Health Administration, also known as MSHA, requires that miners who work at surface mines receive specific safety training to reduce the risk of injury, illness, or fatality on the job.. At some surface mines, the safety training requirements are known as MSHA Part 46.. In particular, Part 46 applies to miners

Surface mining is a method of mining used to extract minerals and metals which are near the surface of the Earth. There are three basic types of surface mining open pit mining, strip mining, and quarry methods are much more economical than underground mining, yet they can have a more significant impact on the surrounding environment unless efforts are taken to reclaim the land.

Mining Mining Underground mining When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for each ton of material mined, are much higher underground than on the
Surface mining is used where the ore or material to be extracted. is located fairly close to the surface. The overlying ground cover. is removed, the material is mined, and the ground cover is
Surface mining is done by removing strippi ng surface vegetation, dirt, and if necessary, layers of bed rock in order to reach buried o re deposits. Techniques of surface mining include open

Strip mining is a type of surface mining that involves excavating earth, rock, and other material to uncover a tabular, lensshaped, or layered mineral reserve.
As a general rule surface mining is more cost effective than subsurface mining. The most common surface mining technique is openpit mining Figure 1, where a commodity is extracted via an open pit in the ground. This is an extremely cost effect way of removing a resource because large quantities can be removed with minimal effort. Other
