In particular, surface mining is used to retrieve sand, gravel, stones, coal, iron and other metals. There are five recognized types of surface mining, each with specific variations depending on the minerals being extracted. These include strip mining, open pit mining, mountaintop removal, dredging and highwall mining.
Jan 30, 2019 Surface mining techniques are categorized as either strip, open pit, or mountaintop removal. Strip mining is a method used on flat terrain and involves removing soil or rock above a layer of coal, exposing the coal seam for mining. One type of strip mining is contour mining, where extraction activities occur on a hillside.
Jul 02, 2021 Strip mining is another way of removing the overburden above the mineral deposit in rows or strips . If the mineral deposit is located deeper into the Earth's crust, miners can dive deep into it using underground mining
Apr 07, 2017 Strip mining and subsurface mining Strip mining or surface 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 lakes, streams, etc gets acidity. Acid mine drainage occurs when water molecules infiltrates the spoil banks. The water reacts with sulfide minerals

Jul 26, 2015 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. Strip Mining Pros to Consider . 1. It is very cost effective.
Minerals are typically excavated by underground mining, strip mining, or open pit mining. The selection of the mine design is dictated by the physical structure and value of the ore body and by the characteristics of the adjacent geological materials.
