6 FAQs about [Stand-type down-the-hole drill rig schematic video]

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.

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.

What are the disadvantages of a DTH drilling rig?

Conventional drilling rigs have cumbersome groundwork in bedrock drilling, frequent lifting and lowering of the drill, large labor consumption, slow speed, and comprehensive calculation of capital consumption, and these disadvantages are difficult to change. DTH drilling rigs mainly use compressed air.

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 do drill rigs work?

Conventional drilling rigs use the power of an electric motor or a diesel engine, which is transmitted to the turntable through the operating system to drive the drill bit connected to the drill rod to grind and cut the rock to achieve the purpose of drilling. This kind of drill first solves the ground power.

What is a down-the-hole drill?

A down-the-hole drill, usually called DTH, is basically a mini jackhammer screwed on the bottom of a drill string.
