Συχνές ερωτήσεις

What is RQD?

RQD stands for Rock Quality Designation. It is the sum of core piece lengths longer than the cutoff, divided by the run length.

Can I enter from/to depths and run length at the same time?

Yes. If both are entered, the tool warns you when the run length and the from/to difference do not line up closely enough.

Can I mix units in the core piece list?

Yes. You can mix unit-tagged values. If a value has no unit, it is interpreted using the current piece unit.

Does it support decimal commas?

Yes. Inputs such as 1,25 are accepted.

Can RQD exceed 100%?

Normally no. If it does, check for unit mistakes or duplicated input.

Γλωσσάρι

RQD

The sum of core piece lengths longer than the cutoff, divided by the run length.

Core recovery

The total recovered core length divided by the run length.

Run length

The total length of the drill interval.

Core piece length

The length of each recovered core fragment.

Cutoff length

The minimum piece length counted toward RQD.

Σημειώσεις

  • This tool is a screening aid, not a replacement for geologic interpretation or mine planning.
  • If you enter both from/to depths and run length, always check unit consistency.
  • Tune the cutoff length and thresholds to your site standards.
  • If a result exceeds 100%, suspect a unit mistake or duplicated input.
