    13/03/2011· Conventional Methods of Surface Mining. Open-pit mining and strip mining are the two major categories of surface mining which account for more than 90% worldwide surface mining production. The primary differences between these mining methods are the location of the ore body and the mode of mechanical extraction. For loose rock mining, the process is essentially continuous with

    07/04/2005· The method evolved from auger mining but does not meet the definition of surface mining since it does not involve the removal of overburden to expose the coal seam. CERB final report No. 2014-004 "Highwall Mining: Design Methodology, Safety, and Suitability" by Yi Luo characterizes it as a "relatively new semi-surface and semi-underground coal mining method that evolved from auger mining

    23/06/2017· All methods of surface mining will remove the waste material, or overburden, above the desired resource. Surface mining is often preferred to sub-surface (underground mining) by mining companies for several reasons. It is less expensive, there are fewer complications in terms of electricity and water and it is safer. This resource from the EPA on surface mining is also worth checking out.

    All surface mining techniques negatively affect the environment, though some methods are more damaging than others. Strip mining. Strip mining, as the name describes, is a process of removing rock and soil in strips to get to the valuable mineral ores below. After miners extract the resources, they put back the leftover rock and soil, called mining spoils or tailings, to fill in the hole. One

    17/10/2020· Surface mining is a method of mining used to extract minerals and metals which are near the surface of the Earth. There are three basic types of surface mining: open pit mining, strip mining, and quarry mining.These methods are much more economical than underground mining, yet they can have a more significant impact on the surrounding environment unless efforts are taken to reclaim the

  • What are the main methods of mining? | American

    There are four main mining methods: underground, open surface (pit), placer, and in-situ mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments.

    High wall mining is another form of surface mining .In this method the Hydraulic Push beam Transfer Mechanism is used to cut across the earth's surface and extract the coal. In this process the machine penetrates deep into the earth's surface to produce large volume of coal. High wall miners have penetrated to the depth of around a thousand feet into the coal seam and capable of going

  • The Actual Difference Between Surface and Underground

    Surface mining is suitable for large, low-grade ore deposits which occur below a thin layer of rock, or alluvial deposits found in sand and riverbeds. Underground mining is used for small, high-grade deposits covered with a thick overburden (soil and rock above the ore), or for deep and sloping deposits. General Process. In all methods of surface mining, first, the overburden is stripped off

    Strip mining (see coal mining ), open-pit (or open-cut) mining, and quarrying are the most common mining methods that start from the earth's surface and maintain exposure to the surface throughout the extraction period. The excavation usually has stepped, or benched, side slopes and can reach depths as low as 1,500 ft (460 m). In strip mining, the soft overburden, or waste soil, overlying the
