6 FAQs about [Down-the-hole drill rig parameters]

What is a DTH drilling rig?

DTH drilling rigs can be utilized in a range of operations, such as mining as well as infrastructure projects drilling for oil and gas exploration as well as the drilling of water wells.

What are drilling parameters?

Drilling parameters play a large role in helping drillers achieve superior drilling performance and long equipment life. They are basic recommendations that help guide a driller avoid burning core bits or damaging other drilling equipment, and help achieve a good rate of penetration and core recovery.

What factors affect drilling parameters?

There is a clear relationship between the drilling parameters and all others factors in drilling, such as the diameter of the equipment you’re using, rock hardness or ground variability. We have seen that when drilling conditions change, drillers will adjust their drilling parameters.

What is air drilling with a pneumatic down-the-hole hammer?

1. Introduction Air drilling with a pneumatic down-the-hole (DTH) hammer, i.e., air hammer, is known as one of the advanced rotary percussive drilling technologies applicable to moderately-to-extremely hard rock formations (Chiang and Stamm, 1998).
