    16/11/2017· Surface mining, also called open pit mining, is used if nearsurface ore body is too large or if it occurs in steeplydipping lodes, pipes, sheeted vein systems, or makes up the majority of the rock in question The entire body of material is mined with no overburden being placed back into the void during the entire extraction process With open pit mining, strip miningMining Mining Underground mining: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered Counting against underground mining are the costs, which, for each ton of material mined, are much higher underground than onMining Underground mining | Britannicasurface is termed underground mining Underground mining methods are usually employed when the depth of the deposit and/or the waste to ore ratio (stripping ratio) are too great to commence a surface operation Once the economic feasibility has been verified, the most appropriate mining methods must be selected according to the natural/geological conditions and spatial/geometricUnderground Mining Methods and Equipment

    The Mining Process 1 Mining – open pit and underground To define the ore from the waste rock, samples are taken and assayed Assay results are used to mark out areas of ore and waste rock, which are mined separately Some of the harder areas require blasting to loosen the rock prior to excavation by hydraulic diggers Dump trucks haul the rock to the primary crushers in the open pit or to21/04/2014· The Difference Between Underground Mining And Surface Mining The process of removal of essential mineral ores or geological substances from soil or sand is called mining These minerals are of great value and are abundantly available in rocks and earth’s surface Minerals can be metallic or non metallic and can be used for a several of purposes Mining is conducted basically inThe Difference Between Underground Mining AndAs compared to underground mining this method of mining removes soil and rock overlying the mineral deposit The equipment used for this process is always heavy such as earth movers, dragline excavators or bucket wheel excavators Types of surface mining Strip mining: This process involves the method of extracting the mineral by removing soil and rock which are deposited on the surfaceCoalSurface mining – strip, open pit, mountaintop removal

    The mine backfill process is the environmental reclamation of the workedout area A Coal is mined either by surface methods (opencut or opencast mining) or by underground techniques In surface mining, all of the rock from the ground surface to the top of the seam (material referred to as overburden) is removed and set aside to expose the coal, which is then taken out and transported25/03/2020· Surface mining, also called strip mining, delivers economically vital supplies of coal, which powers transportation and creates consumer products, boosting local economies This type of mining occurs primarily on mountaintops, and dates back to the early 20th century when new machines made moving earth easier Supporters of surface mining contend it promotes clean energy, producing lessWhat Are the Advantages and Disadvantages of SurfaceMining Mining Underground mining: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered Counting against underground mining are the costs, which, for each ton of material mined, are much higher undergroundMining Underground mining | Britannica

    As compared to underground mining this method of mining removes soil and rock overlying the mineral deposit The equipment used for this process is always heavy such as earth movers, dragline excavators or bucket wheel excavators Types of surface mining Strip mining: This process involves the method of extracting the mineral by removing soil and rock which are deposited on the surfaceCoalWhile mining provides us with the minerals we need, it is also very destructive because it disrupts the landscape both on the surface and underground It also causes quite a bit of pollution andExtraction and Processing of Minerals & theThe mine backfill process is the environmental reclamation of the workedout area A Coal is mined either by surface methods (opencut or opencast mining) or by underground techniques In surface mining, all of the rock from the ground surface to the top of the seam (material referred to as overburden) is removed and set aside to expose the coal, which is then taken out and transportedOpencast Mining an overview | ScienceDirect Topics
