Mine Surveyor.net - Mining Basics - Open Cut Coal

Open cut or surface mining in coal is a suitable choice when coal seams are closer to the natural surface. It is an effective method of retrieving a higher proportion of coal when compared to underground mining. The basic process involves: 1) Exploration 2) Geological Modelling 3) Mine Design 4) Top Soil Stripping 5) Drilling & Blasting

Open-cut mining is one method used to extract these minerals from the earth. Open-cut mining is used when the minerals are found over a large area and relatively close to the surface. The open cut mine is dug downwards in benches or steps which slope towards the centre of the pit. To uncover the minerals the land is first cleared of vegetation as

Strip mining is the process of mining a seam of mineral by removing a long strip of overlying soil and rock. Strip mining is a practical type of mining when the ore body that is to be extracted is near the surface. Open-pit mining is the process of extracting rock or minerals from the earth through their removal from an open pit or borrow.

Open Pit Mining - an overview | ScienceDirect Topics

There are also several categories of surface mining depending on the mining area. The most common is ‘open cut’, where the overburden is removed with ‘draglines’, large ‘electric shovels’ and ‘bucket wheel’ excavators, after it has been drilled and blasted (Fig. 7.7). The overburden is usually loaded into large trucks and removed to a waste area in the mine. The coal is then ‘stripped,’ usually after blasting, …

Open Cut and Underground Mining | iMINCO

Underground Mining is generally used for areas where the mineral seam is too far underground for open cut mining to be of use. A tunnel, called a decline, is created to allow workers and machinery to reach the location of the minerals. Stope mining is used for most hard rock mining of minerals such as copper, silver, lead and zinc. Stopes are large openings or rooms connected by tunnels in ...

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 later when rehabilitating the area once mining is finished.
