FAQS about Down-the-hole drill installation and debugging video

What is a down-the-hole drill?

A down-the-hole drill, usually called DTH by most professionals, is basically a jackhammer screwed on the bottom of a drill string. The fast hammer action breaks hard rock into small cuttings and dust that are evacuated by a fluid (air, water or drilling mud). The DTH hammer is one of the fastest ways to drill hard rock.

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 does DTH drilling work?

With DTH drilling, contractors can change the drill that they were using for the current directional bore to a rock drill when they encounter rock by connecting the drill with a compressor and a steerable hammer. Well drilling also needed changes to be made to rotary drilling when the well needed to take a turn.

How does DTH hammer drilling work?

A flushing current conveys the loosened drill cuttings upwards and exits at the upper end of the casing. If you have any further questions, please contact our local sales or service team. DTH hammer drilling is a percussive drilling process powered by compressed air.

What is a DTH drill?

DTH is short for “down-the-hole”. Since the DTH method was originally developed to drill large-diameter holes downwards in surface-drilling applications, its name originated from the fact that the percussion mechanism followed the bit down into the hole.

How do you drill a rock with a DTH hammer?

This method is mainly applied for hard to very hard rock and/or for penetrating large boulders. 1. Setting the DTH hammer with drill rod and casing on the drilling point. 2. Rotary and percussive drilling of the drill string under compressed air supply. 3. After reaching the final depth, unlocking of the drill rod with DTH hammer and pilot bit.

What is a DTH drill rig?

A down-the-hole drill, usually called DTH Drilling Rig, is basically a mini jackhammer screwed on the bottom of a drill string. The speedy hammer activity breaks hard stone into little flakes and dust and can be dismissed evident by the air exhaust in the DTH hammer.

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 was a hole drilled?

This system could not guarantee a finished hole size and only pure vertical holes could be drilled as the system basically relied on gravity. Debris from the hole was baled out using a baling tube with a clack valve, which was periodically dropped on a winch to capture the slurry, which was then brought to the top of the hole to be discharged.

How does a drill work?

This action along with the rotational movement of the drill string crushes the rock efficiently. Since the piston strikes directly on the bit, energy transfer takes place down the hole with minimum loss of energy, allowing drilling to greater depths. The driving medium i.e. compressed air is also the flushing medium.

How to fix the wire pipe of air compressor video

In this HVAC training video, we're going to explore the reasons behind burned wires in your AC compressor and provide a step-by-step guide on how to change them.

How do you fix a bad air compressor?

Take a check at the crankcase. If it's running low on oil, add extra or replace it. Fixing pistons hitting the valve plate requires a complete engine repair to fix or replace the components causing the clearance issue, which is a difficult process best left to a skilled mechanic. To keep your air compressor running smoothly, follow these steps:

What is air compressor repair?

Air compressor repair involves diagnosing issues and replacing faulty parts to restore functionality. Regular maintenance can prevent many common problems. Air compressors are essential tools in various industries, powering everything from pneumatic tools to HVAC systems.

How do I Keep my air compressor running smoothly?

To keep your air compressor running smoothly, follow these steps: Regularly check and change the air filter to prevent dust buildup. Drain the air tank to remove dampness and prevent rust. Oil the moving parts according to the manufacturer's recommendations. Schedule professional maintenance checks to identify potential issues early on.

How do you fix a leaking air compressor?

Mix up a solution of liquid soap water and apply it around the fittings of the compressor. If there is a leak, you will see bubbles. Power off the compressor and allow the tank pressure to settle. Use Teflon tape to seal the fittings from where the bubbles are forming. Reattach and tighten all the fittings and restart the compressor to refill.

How long does it take to fix a broken air compressor?

You can replace a broken air compressor pressure switch in about 45 minutes. If the air compressor won't fill the tank with compressed air, rebuild the pump using these steps in about 45 minutes. You can replace a defective air compressor check valve in about 10 minutes. Find the perfect fit for your refrigerator.

Why is my air compressor not working?

These issues can stem from worn parts, improper maintenance, or low oil levels. Regular inspections and timely repairs are essential for optimal performance. Addressing these problems quickly can prolong the lifespan of your air compressor. How Can I Maintain My Air Compressor?
