A long metal bar flattened on one end and used to remove loose material from a mine roof or rib.
Industry:Mining
A long open tube fixed above the core barrel in the shot-drill method of exploratory boring. The enlarged space above the sediment tube reduces the upward velocity of the flushing water and the coarse chippings are deposited in the tube where they are retained until drawn up to the surface.

Industry:Mining
A long reverberatory furnace with a series of plows or rakes that are drawn over the hearth by a continuous cable, moving the ore steadily from the feed to the discharge end.
Industry:Mining
A long stabilizer of rectangular shape that when used properly gives a super-packed-hole effect. Square drill collars are made primarily from 30-ft (9.14-m) steel bar stock with a diagonal measurement greater than the hole diameter in which the collar will eventually be used. This collar has proved successful in controlling rapid directional and deviational changes in wells drilled in a disturbed-belt-type area.
