  • An Introduction To Surface Mining

    Mining is merely defined as digging in the ground to find something of use. The process has been a part of life since antiquity, and is still the backbone of the world's commerce and production. Mining could be classified in two forms: mining at the earth's surface (surface mining) and mining underground (subsurface mining).

  • Description of mining methods (step by step)

    Primary Mining Method Sequential grid down dip. Information. To deal with ground pressures, a Vshaped mining sequence is utilized. The main advantages of the sequential down dip method are the very low energy release rates, which make backfilling unnecessary, and the allowance for the physical separation of rock transport from men and materials.

  • Equipment Selection for Surface Mining: A Review

    A surface mine contains pits with mineral endowed rock (or ore). We extract ore that lies within the upper layer of the earth, from surface mines (Fricke, 2006) . This ore can include metals such as iron, copper, coal and gold. There are several methods of surface mining, including openpit, stripping, dredging and mountaintop removal.

  • What are main methods of surface mining?

    Answer (1 of 2): Openpit and area mines are associated with extraction of thick deposits. These justify mining of deeper overburden/cover rock. They are typically multiple bench type operations with special consideration required for the vertical lift requirements of the haulage system. Strip mi...

  • Block Caving Underground Mining Method

    method is likely to be used more widely. Block caving is attractive because it permits very large volumes of ore to be extracted relatively cheaply, increasing production and making lower grade ores economical to mine. Although still more costly than surface mining due to the inherent difficulty of underground operations,

  • Open Pit Mining

    The surface mining methods are: (i) open pit mining, (ii) drift mining, (iii) slope mining, (iv) contour mining, and (v) auger mining. The characteristic that distinguishes open pit mining is the thickness of the coal seam insofar as it is virtually impossible to backfill the immediate mined out area with the original overburden when extremely thick seams of coal are involved.
