3 FAQs about [Korean small rock drill parameters]

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.

How do I find the optimum ROP for diamond drilling?

The ROP is the key parameter in diamond drilling. Finding the optimum ROP for a given type of rock, ground condition, core bit and type of diamond drill rig will improve drilling performance. To find the optimum ROP, you should start by using the ROP suggested on the bit label.
