Cov nyhuv pob zeb tawg ntawm pob zeb diamond khoom yog ua tiav los ntawm pob zeb diamond hais. Txhawm rau paub txog cov nyhuv pob zeb tawg ntawm lub laum me ntsis, nws yog ib qho tsim nyog yuav tsum nkag siab txog lub pob zeb tawg ntawm ib pob zeb diamond. Nyob rau hauv ib qho nyuaj formations, lub pob zeb diamond ib leeg muab lub pob zeb nyob rau hauv lub xeev ntawm kev nyuaj siab heev (txog 4200-5700MPa, ib co ntaub ntawv xav tias nws muaj peev xwm ncav cuag 6300MPa) nyob rau hauv qhov kev txiav txim ntawm drilling siab, uas hloov lub lithology ntawm lub pob zeb. los ntawm brittleness mus rau plasticity. Lub pob zeb diamond ib leeg noj rau hauv kev tsim, thiab nyob rau hauv qhov kev txiav txim ntawm torque, nws txiav thiab tawg lub pob zeb. Qhov tob txiav yog qhov sib npaug ntawm qhov tob ntawm pob zeb diamond lis. Cov txheej txheem no zoo li "cultivating av", yog li nws yog hu ua plow txiav txiav ntawm pob zeb diamond laum me ntsis.
Hauv qee cov pob zeb nkig (xws li sandstone, limestone, thiab lwm yam), qhov ntim ntawm cov pob zeb tawg yog ntau dua qhov kev noj thiab kev sib hloov ntim ntawm cov pob zeb diamond hais raws li qhov kev txiav txim ntawm qhov drilling siab torque ntawm pob zeb diamond hais ntawm lub laum me ntsis. . Thaum lub siab tsis siab, cov grooves me me tuaj yeem tsim tau raws li cov kev taw qhia ntawm pob zeb diamond txav, thiab nce siab yuav ua rau cov pob zeb nyob rau hauv qhov sib sib zog nqus ntawm cov zawj me me thiab ntawm ob sab, tshaj qhov hla ntawm qhov loj ntawm pob zeb diamond hais.
Cov nyhuv pob zeb tawg ntawm pob zeb diamond laum khoom tsis yog tsuas yog cuam tshuam nrog lithology thiab lwm yam cuam tshuam rau lithology (xws li siab, kub, tsim kua dej, thiab lwm yam), tab sis qhov hnyav ntawm me ntsis yog qhov tseem ceeb cuam tshuam. Zoo li cov menyuam lub khob hliav qab me ntsis, nws muaj peb txoj kev ntawm nto crushing, qaug zog crushing thiab ntim crushing thaum tawg pob zeb. Qhov zoo tshaj plaws pob zeb tawg tuaj yeem ua tiav tsuas yog thaum cov pob zeb diamond hais muaj qhov tshwj xeeb txaus los noj rau hauv cov pob zeb tsim thiab ua rau lub pob zeb tawg.
