Mining - Surface mining Britannica

There are several types of surface mining, but the three most common are open-pit mining, strip mining, and quarrying. These differ from one another in the mine geometries created, the techniques used, and the minerals produced. Open-pit mining often (but not always) results in a large hole, or pit, being formed in the process of extracting a mineral. It can also result in a portion of a hilltop being removed. In strip mining

Advances in coal mining technology - ScienceDirect

2013-1-1  In recent years, new types of equipment and machinery have been introduced to the surface mining. The Wirtgen surface miner can effectively mine softer material, particularly coal not needing blasting. It uses a cutting drum driven by its engine to cut into the seam, remove the coal, and convey it to either a truck or transport conveyor for haulage.

Open Pit Mining - an overview ScienceDirect Topics

Surface mining is perhaps the most dramatic direct human disturbance at the landscape scale(Figs. 3 and 4) and there are a variety of types of surface mining, each of which results in different types and intensities of landscape disturbance (Table II). In general, the selection of mining methods is based on economics as influenced by the topography, thickness of overburden, and character of the resource.

The Impact of Surface and Coal Mining on Environment

2021-3-29  Surface mining often leads to acid mine -drainage and silt run off which de­grades quality of water. Acid mine drainage is an important source of increased acidity in natural waters. Its main constituents are sulphuric acid and iron compounds formed as a result of water, air and pyrite and are drained into the natural water sources.
