    Surface Mining Methods and Equipment

    Surface mines have very few limitations on the operation of large machines with high capacity, whereas underground operations are considerably restricted by narrow working spaces and rock conditions. Moreover, less commuting time is required at a surface mine, whereas a much longer time is consumed by transportation in an underground mine because of the typically long distance from the mine

    Digging deeper: Mining methods explained Anglo American

    Open-pit is one of the most common mining methods used and starts from the earth's surface, maintaining exposure to the surface throughout the extraction period. The excavation usually has stepped sides to ensure the safety of the miners and a wide ramp where equipment can travel, allowing the product to be removed efficiently from the site. Open-pit mining is practical when the ore-bodies of

    Costcutters: Efficiency and productivity in mining

    So the open-pit mines have tended to get more productive, but at the underground mines, where you have a bunch of workers, they all go underground in a cage, they all go off to their working places, it's very difficult to monitor what everyone is doing and your short interval control is harder. Open-pit offers a lot more opportunities, and that's one of the reasons it's so attractive. There
