Frequently asked questions
Apa is RQD?
RQD stands untuk Rock Kualiti Designation. It is sum daripada teras kepingan panjang longer than cutoff, divided by run panjang.
Can I enter daripada/ke depths dan run panjang pada sama time?
Yes. If kedua-duanya are entered, alat warns you when run panjang dan daripada/ke difference do not line up closely enough.
Can I mix unit in teras kepingan list?
Yes. You can mix unit-tagged values. If value has no unit, it is interpreted menggunakan semasa kepingan unit.
Does it support decimal commas?
Yes. Inputs such as 1,25 are accepted.
Can RQD exceed 100%?
Normally no. If it does, check untuk unit mistakes atau duplicated input.
Glossary
RQD
sum daripada teras kepingan panjang longer than cutoff, divided by run panjang.
Teras pemulihan
total recovered teras panjang divided by run panjang.
Run panjang
total panjang daripada drill selang.
Teras kepingan panjang
panjang daripada each recovered teras fragment.
Cutoff panjang
minimum kepingan panjang counted toward RQD.

Nota
- This alat is screening aid, not replacement untuk geologic interpretation atau mine planning.
- If you enter kedua-duanya daripada/ke depths dan run panjang, always check unit consistency.
- Tune cutoff panjang dan thresholds ke your site standards.
- If hasil exceeds 100%, suspect unit mistake atau duplicated input.
