Diamond Drilling: Technical Overview for Practitioners
Principle of Diamond Drilling Diamond drilling [1] relies on the extreme hardness and abrasion resistance of diamond to cut virtually all rock types encountered in mineral exploration. Material removal is achieved by grinding rather than impact, producing a cylindrical core suitable for geological logging and analysis. A typical diamond drilling system consists of: a power unit...

Vibration in Diamond Drilling
What causes it, what it costs you, and how to fix it. Why it matters Vibration wastes cutting energy. Instead of steady torque driving the bit, you get cyclic bending and impact. The result: Lower core recovery. Faster diamond wear and loss. More wear on rods, couplings, and barrels. Lower ROP at the same WOB. Can't run the RPM you need without the string going...
