  • Environmental Consequences of Open Pit Mining

    An open pit mine is a type of excavation where surface and subsurface materials (soil and rock) are removed, typically through use of explosives and mechanical mining and hauling equipment, to gain access to commercially valuable ores or other buried natural resources, including coal and gemstones, that are relatively close to the surface.

  • An Overview of the Open Pit Mining Process

    Mar 02, 2016Open-pit mining which is sometimes referred to as open cut mining, opencast mining or simply strip mining is a mining technique that extracts important minerals from a borrow or an open pit. There are two types of mining methods commonly used in large scale mineral mining; open pit mining and tunneling. Open pit mining is used when the minerals to be mined are located just close

  • Strip Mining vs Open pit mining : mining

    As such, the 'mine' moves across the land over time. Open pits are for deposits that are tilted or even vertical. Extraction is limited to a relatively smaller area, and the mining operation moves down over time. To dig deeper, the pit also has to be widened over time, increasing the ratio of overburden:ore.

  • Use of an artificial crown pillar in transition from open

    Open pit mining is widely used in large orebodies at shallow depth or that outcrop on surface. 1 The depth of open pit mines is restricted by the stripping ratio. When the open pit mine reaches its designed ultimate depth, with ore remaining below this limit, the mine often evolves from open pit to underground mining.

    Techniques of surface mining include: open-pit mining, which is the recovery of materials from an open pit in the ground, quarrying, identical to open-pit mining except that it refers to sand, stone and clay; strip mining, which consists of stripping surface layers off to reveal ore/seams underneath; and mountaintop removal, commonly associated

    Underground mining. Once a decision has been made to go underground, the specific mining method selected depends on the size, shape, and orientation of the ore body, the grade of mineralization, the strength of the rock materials, and the depths involved.
