  • Openpit mining Wikipedia

    Openpit, opencast or open cut mining is a surface mining technique of extracting rock or minerals from the earth by their removal from an open pit or borrow This form of mining differs from extractive methods that require tunnelling into the earth, such as long wall miningOpenpit mines are used when deposits of commercially useful ore or rocks are found near the surfaceMining is something quite extraordinary When we think of mining we think dusty, dark, unflattering settings In contraire it is quite in fact the opposite So what is open cast mining? Open cast mining is the removal of rocks or sediments that contains minerals, with economically important elements The advantages of open cast mining:What is the difference between opencast & underground mining?

  • Coal mining Wikipedia

    When coal seams are near the surface, it may be economical to extract the coal using open cut (also referred to as open cast, open pit, mountaintop removal or strip) mining methods Opencast coal mining recovers a greater proportion of the coal deposit than underground methods, as more of the coal seams in the strata may be exploited This equipment can include the following: Draglines whichOpen Cast and Underground Mining Machines Nearby schools & colleges Happy Feet Ballet 73 Marais Str Genza Mining Skills And Machine Operator Training pty LTD 33 Steen Street SA Mining and Operator Training College 53 corner Nelson Mandela drive andOpen Cast and Underground Mining Machines, Plot 30
