  • Open Pit Mining an overview ScienceDirect Topics

    Open-pit mining is the process of extracting rock or minerals from the earth through their removal from an open pit or borrow. Figure 8.8. Open-pit mine [16]. Surface mining is usually used to develop coal seams and deposits of many other minerals, but their feasibilities vary with the nature of the body ore.

  • Surface Mining Methods and Equipment

    Highwall mining is a coal mining method for recovery of outcropped coal by mechanical excavation without removal of overburden. A continuous miner with single or multiple augers/cutting heads is operated underground and controlled remotely by crew located outside. Augering can be regarded as a supplementary method for open cast mining in cases when coal seams in the highwall would

  • Smart Options for Open-pit Mining Coal Age

    Most mined commodities are recovered using open-pit mining methods. Oftentimes, these activities take place in remote locations in extreme conditions that could range from high-altitude arctic to high-temperature arid deserts. To mine year-around in these conditions requires dedication and robust equipment that operates for extended periods of time. More recently, mining operations in general

  • Coal mining Wikipedia

    When coal seams are near the surface, it may be economical to extract the coal using open cut (also referred to as open cast, open pit, mountaintop removal or strip) mining methods. Opencast coal mining recovers a greater proportion of the coal deposit than underground methods, as more of the coal seams in the strata may be exploited. This equipment can include the following: Draglines which
