Laum cov khoom yog cov cuab yeej tseem ceeb hauv Geotechnical engineering, mining, thiab kev tsim kho. Kev txhim kho thiab kev siv ntawm lawv cov qauv kev tsim kho ncaj qha cuam tshuam kev ua haujlwm ua haujlwm, kev nyab xeeb, thiab tswj kev nyab xeeb. Qauv laum cov kev tsim kho kev tsim kho cov qauv kev tsim kho muaj txoj kev xaiv nruj thoob plaws plaub thaj chaw: cov txheej txheem kev ua haujlwm, tswj hwm kev nyab xeeb thiab kev nyab xeeb.
Cov cuab yeej xaiv thiab sib xyaw yog lub hauv paus ntawm kev tsim qauv. Laum qeb (xws li carbide laum cov khoom thiab cov pob zeb diamond laum) yuav tsum muaj qhov tseeb rau cov qauv ntawm geological) thiab kev tsim kho qauv (coring, cringing). Piv txwv li, pob zeb diamond laum yog nyiam rau cov pob zeb tawv tawv, thaum cov menyuam lub khob can tho yog qhov haum rau cov kev tsim tawm. Tsis tas li ntawd, laum me me thiab hom kev sib txuas yuav tsum muaj kev sib dhos nrog kev ua kom poob qis lossis khoom siv kev puas tsuaj rau kev kho tsis raug.
Cov txheej txheem kev ua haujlwm ua haujlwm yog qhov tseem ceeb los ua kom zoo dua qub. Laum cov khoom yuav tsum tau kuaj ua ntej kev tsim kho ua ntej kev tsim kho kom ntseeg tau tias lawv muaj kev ywj pheej thiab hnav ntau dhau. Thaum lub sijhawm tho, qhov nrawm, siab, thiab cov khoom xa tawm yuav tsum tsis txhob tswj hwm kom tiv thaiv kev kub ntxhov thiab deflection. Piv txwv li, thaum drilling tawv pob zeb, qhov qis}} ceev} nrawm hom yuav tsum tau, thaum lub pob zeb muag muag, qhov nrawm tuaj yeem nce siab. Tsis tas li ntawd, tho tsis (xws li tus nqi footage thiab kev hloov pauv ntawm tes) yuav tsum tau sau tseg kom muab cov ntaub ntawv txhawb nqa rau cov haujlwm tom ntej.
Kev tswj kom zoo thiab kev nyab xeeb qauv tau ua tiav thoob plaws txhua txoj kev. Thaum kev tsim kho, drilling qhov tseeb yuav tsum tau ua kom tiav los ntawm cov hau kev xws li cov pob zeb txheeb xyuas, thiab muab pov tseg qhov tob yuav tsum tau hloov kom sai. Hais txog kev nyab xeeb, cov neeg ua haujlwm yuav tsum tau cov khoom tiv thaiv tiv thaiv, drilling cov paib yuav tsum tau nyob hauv high- voltage chaw.
Hauv cov ntsiab lus, nruj kev ua kom laum kev tsim kho cov qauv yog qhov tseem ceeb rau kev ua haujlwm ntawm txoj haujlwm. Kev Xaiv Kev Tshawb Fawb, kev ua haujlwm raws cai, thiab kev soj ntsuam kev ua tau zoo tuaj yeem txhim kho kev tsim kho thiab kev nyab xeeb, thaum txo cov nqi tag nrho. Cov neeg tuaj koom kev lag luam yuav tsum txuas ntxiv ua kom zoo dua lawv cov qauv hloov pauv kom haum rau cov kev coj ua thiab kev hloov pauv.
