FAQS about Down-the-hole drill slag removal video tutorial

What is a down-the-hole drilling method?

The video shows the down-the-hole drilling method for very hard soil or rock. A rotary drilling rig, type LB 20, working with down-the-hole hammer inside a casing. A flushing current conveys the loosened drill cuttings upwards and exits at the upper end of the casing.

How does a down-the-hole drill work?

In down-the-hole drilling a drill rod is fitted with a hammer at its lower end. The hammer, which is mounted on the drill bit, is activated through the addition of compressed air and driven into the ground – simultaneously rotating and impacting. A flushing current collects the loosened drill cuttings and conveys them upwards.

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 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.

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.

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?

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 drilling (DTH)?

Down-the-hole drilling (DTH) essentially involves a drilling hammer at the bottom of a drill string. It relies on three elements for drilling holes: bit loading (weight), rotation and air. These active elements combine to be efficient at crushing rock. As the drill string slowly rotates, the drilling hammer is forced into the rock repeatedly.

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.

Why is DTH drilling better than top hammer drilling?

DTH drilling offers several advantages over top-hammer drilling for larger, deeper holes in medium-hard formations. Because the hammer is at the bottom of the hole, power loss is minimal as the hole deepens.

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 makes a DTH drill system different from other drilling systems?

The advent of tungsten carbide for the drill bits (the first bits were all-steel) and the development of the button drill bit coupled with the introduction of high air pressures (25 bar plus) has meant that the DTH system can compete easily and efficiently with other drilling systems.
