Low-recuperare long run
Intrare Run lungime 10 ft, miez pieces 18 in / 12 in / 8 in
Rezultat RQD 31.7%, miez recuperare 31.7%, pierdere flag shown
Întrebări frecvente
What is RQD?
RQD stands for Rock Calitate Designation. It is the sum of miez piece lengths longer than the prag, divided by the run lungime.
Can I enter from/to depths and run lungime at the same timp?
Da. If both are entered, the instrument warns you when the run lungime and the from/to difference do not line up closely enough.
Can I mix unități in the miez piece list?
Da. You can mix unitate-tagged values. If a valoare has no unitate, it is interpreted using the curent piece unitate.
Does it support decimal commas?
Da. Intrares such as 1,25 are accepted.
Can RQD exceed 100%?
Nurmally no. If it does, verifică for unitate mistakes or duplicated intrare.
Glossary
RQD
The sum of miez piece lengths longer than the prag, divided by the run lungime.
Miez recuperare
The total recovered miez lungime divided by the run lungime.
Run lungime
The total lungime of the foraj interval.
Miez piece lungime
The lungime of each recovered miez fragment.
Prag lungime
The minimum piece lungime counted toward RQD.

Nutes
- This instrument is a screening aid, not a replacement for geologic interpretation or mine planificare.
- If you enter both from/to depths and run lungime, always verifică unitate consistency.
- Tune the prag lungime and thresholds to your site standards.
- If a rezultat exceeds 100%, suspect a unitate mistake or duplicated intrare.
