6 FAQs about [What to do if a down-the-hole drill rolls over during construction]
What is down-the-hole (DTH) drilling?
Down-the-hole (DTH) drilling has made it easier for contractors to drill wells faster and more efficiently, and to transition from dirt boring to rock boring just by adding a compressor and hammer to the drill bit.
How long did it take to drill a 12,000 ft hole?
The original estimate for completion of a 12,000-foot hole was 30 days using the conventional rotary technique, which was reduced to 13 days using the DTH method. Before DTH was used, drillers would typically case the vertical portion of the well and convert to rotary drilling to drill at a tangent.
How does a DTH drill work?
DTH equipment consists of a drilling hammer and a piston-powered by compressed air. As the drill string rotates, the drilling hammer strikes down on the rock. The drill bit receives its striking power from a piston inside the hammer that is powered by compressed air.
What is a down the hole hammer?
One of the most commonly used tools in the drilling industry to meet such challenging scenarios is the Down the Hole Hammer (DTH hammer). DTH hammers are most used in hard rock formations and are designed to tackle complex tasks like drilling in populated areas without putting existing structures at risk.
How do you protect yourself during a hammer drill?
Protect your head with a hard hat, ear guards and eyewear that deflects matter thrown into the air during hammer use. Protect your hands with durable work gloves, and your feet with sturdy steel-toed shoes or boots. Always be aware of your drilling conditions.
Can you use a hammer to clean a drill?
Do not use it to clean anything but the hammer, and make sure it doesn’t blow anything into the hammer. All safety precautions must be followed. Improper or negligent use of hammers and other drilling products can result in bodily injury or death to persons, and/or severe damage to the hammer and parts.
