Modern Strategic Mine Planning

In mine planning, decisions as to how and when to act include the extraction and routing of blocks of ore, the timing of lumpy decisions such as pushbacks or transitions from open pit to underground mining, and the placement of shafts. As with financial options, the goal is to take actions that optimize the present value of the payoffs from acting.

Lecture 4: Underground Mining

 · Shortwall mining A coal mining method that accounts for less than 1% of deep coal production, Shortwall involves the use of a continuous mining machine with moveable roof supports, similar to longwall. The continuous miner shears coal panels 150–200 feet wide and more than a halfmile long, depending on other things like the strata of the Earth and the transverse waves.

Hashima Island: A Forgotten World

To delve a bit further into the history of Hashima's mining past, coal production had recently expanded on a nearby island named Takashima and in April 1869, a 150foot deep coal bed was found which brought vast riches to the operation – this influenced a rush for more mining in the area, including the thendormant Gunkanjima.

For example, in coal and other soft rock mines, continuous miners break and load the mineral to eliminate drilling and blasting; boring machines perform the same tasks in mediumhard rock. The cycle of operations in surface and underground mining differs primarily by the scale of the equipment.

How Underground Mining Works | HowStuffWorks

Underground mines are the alternative to surface mines. Surface mines excavate from the top down, a method that can become inefficient at depths greater than about 200 feet (60 meters) [sources: Illinois Coal Association, De Beers].Undergrounds coal mines can drive 2,500 feet (750 meters) into the Earth and other types even deeper uranium mines can reach 6,500 feet, or 2 kilometers.
