    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 and Underground Mining iMINCO. Open Cut Mining.

    If a shearer cuts coal at a given rate, the effect on the haulage system will be different depending on the direction of cut – when cutting towards the tailgate the coal is carried away from the shearer while the shearer is moving away from the cut location; when cutting to the maingate the shearer is travelling in the same direction as the cut coal and so tends to load fresh coal on top of that already on the AFC.

    2018-6-27  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

    2021-5-7  In most mining areas, it is box cut that serves as the first step in the excavation process. Outlining a box shape, it consists of a single rectangular cut made in the surface of the earth. In general, this type of mining technique is used for extracting coal, however it is applied to other material types i.e., from metals to minerals.

    This is achieved by "snaking" the AFC on which the shearer travels, so that the cutter drum can cut a wedge shaped section of coal until the full depth of the web is attained. It is possible to cut a full web in one pass and to do this in either direction, a process known as "Bi-directional or Bi-di cutting" .

  • Spatial assessment of open cut coal mining

    2016-12-1  Worldwide coal mining has expanded over the past few decades, though growth has recently slowed due to reduced demand, partly due to concerns around CO 2 emissions and climate change impacts. Coal mining is also a significant driver of land disturbance in regions where economic coal seams and coal mining methods are applied, in particular open cut extraction.

During this process, workers start by creating a box cut deep enough to reach the start of the coal deposit. This box cut serves as an access point for deeper mining. For example, a shaft may be drilled from inside the trench to the ...
