Qhov hnyav ntawm pob zeb diamond laum rods tuaj yeem sib txawv nyob ntawm seb qhov ntev thiab txoj kab uas hla ntawm tus pas nrig, nrog rau cov khoom tshwj xeeb thiab cov qauv siv hauv lawv cov kev tsim kho. Feem ntau, pob zeb diamond laum rods yog tsim los ua lub teeb yuag kom yooj yim ntawm kev tuav thaum lub sijhawm ua haujlwm drilling. Qhov hnyav yog feem ntau teev nyob rau hauv cov nqe lus ntawm qhov hnyav ntawm ib chav tsev ntev (piv txwv li, kilograms ib meter lossis phaus ib ko taw).

Raws li cov lus qhia dav dav:

Standard Exploration Core Drill Rods:
Feem ntau siv pob zeb diamond laum pas nrig rau kev tshawb nrhiav pob zeb, xws li BQ, NQ, HQ, thiab PQ rods, tej zaum yuav hnyav li ntawm 1.5 txog 3 kilograms ib 'meter' (0.5 mus rau 1 phaus ib ko taw), nyob ntawm seb qhov loj me thiab tsim.

Thin-wall Pob Zeb Diamond Drill Rods:
Nyias-phab ntsa pob zeb diamond laum rods, siv rau kom tau cov tub ntxhais loj diameters nrog txo cov khoom pov tseg, tej zaum yuav sib zog, feem ntau yog li ntawm 1 mus rau 2 kilograms ib 'meter' (0.3 mus rau 0.7 phaus ib ko taw ).

Tshwj xeeb los yog Heavy-duty Drill Rods:
Hauv qee qhov kev siv, xws li kev sib sib zog nqus drilling lossis nyuaj geological tej yam kev mob, tshwj xeeb los yog hnyav-duty pob zeb diamond laum rods tej zaum yuav muaj ib tug ntau dua qhov hnyav ntawm ib chav tsev ntev.
