DetailsLet's follow the chain of events within a crushing cycle to see how they all go together. The first component of the crusher is the drive motor. This will drive a reducer sheave that is attached to an eccentric shaft. On the other end of the shaft is the flywheel. The purpose of the flywheel is to generate energy in the form of motion.
DetailsUpcast shaft — A shaft through which air leaves the mine. Uraninite - A uranium mineral with a high uranium oxide content, often found in black pitch-like masses. Uranium - A radioactive, silvery-white, metallic element used as a fuel in nuclear reactors and in the manufacture of atomic bombs.

DetailsOnce the area is surveyed and mining engineers develop plans for the underground mine, construction will begin. The shaft, a vertical tunnel used to move from the surface to different levels of the mine, is created.. By drilling holes and inserting explosives inside, miners blast openings into the rock.
DetailsShaft mining or underground mining is used when t he minerals or coal layers are deep under the surface. A shaft is drilled and blasted into the ground. Then tunnels are dug out horizontally from the shaft. A lift system is used to take the miners down into the mine and back to the surface again. The deeper we go into the earth, the hotter it ...

DetailsDeep-shaft mining: This uses the 'room-and-pillar' method, where shafts sink to the bottom of a mine and 'rooms' are created through cutting, drilling and blasting between these shafts in a checkerboard-like pattern; leaving supporting 'pillars'. Once operational, machinery can then extract and crush the salt.
DetailsThe purpose of this paper is to cover some aspects which have to be considered when designing mine shafts. It is hoped that this paper will be used throughout industry as a quantitative basis for the comparison of various mine access options both for new and existing mines. This should form an integral part of any mine design process.
