4.3 - Auger Drilling

Auger drilling uses direct power to rotate (screw) flighted augers into the ground. Drill rigs must have kill

switches in operable condition. Familiarize yourself with their location and operation. At least two persons

must be present when operating the rig. Do not wear loose clothing, jewelry, hair, or equipment near the

auger

The operator and tool handler should establish a system of responsibility for the series of various activities

required for auger drilling, such as connecting and disconnecting auger sections, and inserting and removing

the auger fork. The operator must assure that the tool handler is well away from the auger column and that

the auger fork is removed before starting rotation.

Be aware of the following hazards which may be unique to this type of drilling:

• Clean the auger’s male and female ends with a wire brush. Do not clean out bolt holes with your fingers.

When applicable, couple the rig to the next auger while that auger is on the ground, then allow the machine

to pick it up and place it on the down-hole string. Idle the machine down before engaging the rotation.

• Only use the manufacturer's recommended method of securing the auger to the drill drive coupling. Do

not touch the coupling or the auger with your hands, a wrench, or any other tools during rotation.

• Whenever possible, use tool hoists to handle auger sections.

• Never place hands or fingers under the bottom of an auger section when hoisting the auger over the top

of the auger section in the ground, or over other hard surfaces such as the drilling rig platform.

• Never allow feet to get under the auger section that is being hoisted.

• Prepare to start an auger boring with the drill rig level, the clutch or hydraulic rotation control

disengaged, the transmission in low gear, and the engine running at low RPM.

• Use low-profile auger pins.

• Apply an adequate amount of down pressure prior to rotation to seat the auger head below the ground

surface.

• Look at the auger head while slowly engaging the clutch or rotation control and starting rotation.

• When rotating augers, stay clear of the rotating augers and other rotating components of the drilling rig.

Never reach behind or around a rotating auger for any reason whatsoever.

• Slowly rotate the auger and auger head while continuing to apply down pressure. Keep one hand on the

clutch or the rotation control at all times until the auger has penetrated about 1 foot or more below the

ground surface.

• If the auger head slides out of alignment, disengage the clutch or hydraulic rotation control and repeat

the hole starting process.

• An auger guide can facilitate the starting of a straight hole through hard ground or a pavement.

• Never place your hands between the drill rig and an auger, even when attempting to free damaged or

bound sampling equipment from the auger.

• Use a long-handled shovel to move auger cuttings away from the auger. Never use hands or feet to move

cuttings away from the auger. It is preferable to move cuttings while the auger is inactive.

• Augers should be cleaned only when the drill rig is in neutral and the augers have stopped rotating.

• After loosening the top auger from the down-hole string, allow the machine to pick up the auger off of

the string and set it on the ground, then uncouple from the machine.

• Care should be taken to ensure augers are properly stored and secured when not in use and during

transport.
