In surface mining, the ore is accessed directly from the earths 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. working principleapr 07, 2017 strip mining and subsurface mining strip mining is performed when surface soil and rock are stripped off to reach the mineral of concern. when such operations are done, surface water bodies gets acidity. acid mine drainage occurs when water molecules infiltrates the spoil banks. the water reacts with sulfide minerals to produce sulfuric acid.
strip mining is a kind of surface mining. the ore is very near to the surface of the land but has one or more layers of rock and filth on top of it. To mine the ore, these layers have to be removed. the steps in strip mining are similar to open-pit mining.open-pit mining: this type of mining involves the extraction of rock or minerals from the earth by forming an open pit. this process differs from the other method which requires digging into the earth. this method of mining is carried out where useful minerals or rocks are found near the surface.feb 27, 2016 explanation: but briefly, strip mining is economically necessary to extract some mineral resources, such as coal, when the overburden is not too thick. In such cases, an underground mine would be costly and probably unsafe. answer link.aug 22, 2017 working underground is usually a hot, noisy, humid, and dark business, but working in an open pit mine can expose workers to weather conditions, which can cause problems as well. working in the mining industry in any capacity is hard work that demands exceptional concentration and talent in order to stay safe in the environment of heavy materials, heavy equipment, and hard work.

open cut mining. there are many differences between open cut and underground mining. when minerals and deposits are found close to the surface and spread across a large distance, the best way to mine is to use the open cut mining method. In this process, the area is cleared of all topsoil and vegetation, this material is stockpiled and used open-pit mining, or open-cast mining is a surface mining technique of extracting rock or minerals from the earth by their removal from an open pit or borrow.. this form of mining differs from extractive methods that require tunneling into the earth, such as long wall mining. open-pit mines are used when deposits of commercially useful minerals or rocks are found near the surface; that is jul 11, 2010 open-pit mining is the extraction of mineral ores or solid fossil fuels that occur in seams or strata that are located near the surface. It involves the removal of surface overburden material, and open-pit is one of the most common mining methods used and starts from the earths surface, maintaining exposure to the surface throughout the extraction period. the excavation usually has stepped sides to ensure the safety of the miners and a wide ramp where equipment can travel, allowing the product to be removed efficiently from the site.
In open-pit mining waste is transported to a disposal site, and the ore is transported to a downstream processing site. this method commonly involves a sequence of benches from the surface to the deposit. As the open pit goes deeper into the ground, all of the benches above are extended outward.difference between open cast and open pit mining products.
