6 FAQs about [Down-the-hole rotary drill video tutorial]

What is down-the-hole hammer drilling?

Down-the-hole hammer drilling is a method where the drill principle consists of a combination of percussion and rotation. In this method, the hammer drill is located directly in the borehole, and these devices, known as ‘down-the-hole hammers’, are connected to the rotating drill pipes.

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 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.

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 is a down-the-hole hammer used?

Down-the-hole hammers are used for drilling boreholes into hard rock in bedrock. The flushing medium is forced through the drill pipes, down-the-hole hammer, and drill bit, and is expelled back out at the mouth of the borehole, along with the drill cuttings, through the annular gap between the drill pipes and the borehole wall.

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.
