Glossary of Terms
The following is a list of terms commonly used in the mining and construction industry. This list is not exhaustive, but pertains primarily to surface track drills as discussed in this manual.
Anti-Jam ........................A hydraulic system that senses a change in drill rotation and automatically retracts and extends drill steel to get through “bad ground” and prevent steel from getting stuck.
Belleville Washer ...........Another name for “Spring Washer”.
Bleed(ing) ......................A procedure to remove trapped air from a fluid.
Boom ............................Horizontal structure that supports and positions the feed. One end attaches to a pivot at the boom bulkhead at the front of the machine, the other end attaches to the positioner. Some booms are extendable, others are fixed (non-extendable).
Centralizer ....................A device used to keep the drill steel centered with respect to the centerline of the feed. An end centralizer is located at the bottom end of the feed. It has jaws that open and close around the drill steel, but allow the drill steel to pass through and rotate freely. The jaws are also used to clamp around the drill steel coupling and hold it tight for threading and unthreading of drill steel. A mid-point or travelling centralizer is used on long feeds to support the midpoint of the drill steel.
Collar(ing) ......................A term referring to starting a hole, whereby reduced hammer and feed pressure is used to get a hole started straight.
Detergent Tank..............A holding tank for water and detergent solution that is sometimes pressurized, or used in conjunction with a pump. It is part of a system used to suppress dust from the hole by means of injecting water into the hole while drilling is in progress. A detergent solution is mixed with water to act as a lubricant for the drill bit.
Drill Rod........................Another name for “drill steel”.
Drill Steel......................A specially made length of steel with threads on both ends to allow coupling together and to the drill shank and drill bit. The drill steel transfers energy from the drill to the bit and is also used to convey air or water for hole cleaning.
Drill Steel Coupling.........A devise used to join two pieces of drill steel together and to join the drill steel to the drill shank, by means of internal female threads or sometimes male and female threads.
Drill String.....................Refers to multiple pieces of drill steel joined together.
Dump............................Term used to describe the position of the feed relative to the centerline of the boom. Dump UP tilts top of feed towards boom, dump DOWN tilts top of feed away from boom.
Dust Collector...............A device used to collect dust and cuttings from the hole by means of vacuum, while drilling is in progress.
Extend ..........................To move object OUT or AWAY from machine in the horizontal plane, or to move object TOWARD the ground in the vertical plane.
x Introduction
BI620156
Feed .............................Structure used to support the rock drill, drill steel and rod changer. The rock drill moves up and down the feed by means of a chain drive system, or in some cases a cable or hydraulic cylinder drive system. Feeds come in various lengths, depending on length of drill steel required.
Feed Mounting...............Another name for “Feed Table”
Feed Table ....................A device that attaches to the positioner by means of a pin and hydraulic cylinder, and is used to support the feed.
Hammer(ing) ..................A term used to describe the action of the drill hammer or piston striking the drill shank, thus transferring the blow energy through the drill steel to the bit.
Oscillation .....................Refers to the up and down movement of the tracks. During tramming the track oscillation cylinders are unlocked to allow the tracks to move up and down according to the terrain. During drilling the track oscillation cylinders are locked, to prevent the tracks from moving.
Pickup Pot.....................A device that can be hydraulically raised or lowered over the hole and provides a means of attaching the dust collector hose to remove dust and cuttings from the hole.
Positioner ......................A device attached to the end of the boom, that allows the feed to pivot and be positioned at various angles.
Pre-Cleaner ...................A device used in conjunction with the dust collector, that removes large particles before they reach the dust collector.
Rattle ............................A term used to describe loosening the drill string joints by “hammering” the drill steel, by using short bursts of the hammer with no feed pressure on the drill bit.
Retract .........................To move object IN or TOWARDS the machine in the horizontal plane, or to move object AWAY from the ground in the vertical plane.
Rock Drill.......................The device that provides the percussive and rotation forces for drilling. Sometimes referred to as the “hammer” or “drifter”.
Shank ............................A specially made short length of steel with splines at one end and threads at the other end. The splined end is inserted into the rock drill and engages the splines of the chuck end of the drill. The drill steel attaches to the other end by means of a coupling.
Spring Washer...............A cup shaped washer that, when compressed provides a “spring like” action. Also called "belleville washer".
Sting .............................To apply pressure to the ground by extending the feed to prevent the feed from moving while drilling.
Stinger ..........................A device attached to the end of the feed which contacts the ground to stabilize the feed while drilling.
Swing ............................Term used to indicate movement of a component to right or left, relative to machine as viewed from rear.
Tram.............................To move and steer the machine from the tram station or operator’s cab.
