Cov Khoom Siv Qhia Txog Khoom

Lub kaw lus tsim khoom ntawm Kev Lag Luam Mining yog ib qho system nyuaj uas muaj ntau qhov txuas.
Hauv kev khawb thee, cov xwm txheej geological thiab hydrologic nyuaj, alluvium tuab ntawm cov av saum toj kawg nkaus, ntau txheej xuab zeb quicksand, dej ntws loj, lub qhov dej loj, lub qhov dej tob, thiab feem ntau yog qhov ua haujlwm sib sau ua ke, nrog rau qhov kub siab, siab siab thiab kev ntxhov siab siab hauv lub qhov dej tob, yuav ua rau qhov nyuaj ntawm cov av hauv av thiab qhov nyuaj ntawm kev kho.
Qee qhov teeb meem yuav tsum tau daws raws li cov yam ntxwv ntawm kev khawb av thee:
1. Qhov teeb meem ntawm kev nce qhov ceev ntawm drilling.
2. Kev tiv thaiv thiab kho qhov dej tawg, txo qhov loj me, kev khawb poob thiab lwm yam xwm txheej.
3. Kev siv tshuab tiv thaiv kev hloov pauv.
4. Kub siab ua haujlwm.
5. Teeb meem ntawm cov cuab yeej txiav hauv kev tsim kho qhov dej tob.
Xaiv cov pob zeb drilling bits kom zoo yog qhov tseem ceeb heev ua ntej pib qhov project.
Qhov nyuaj ntawm pob zeb yuav yog mos, nruab nrab thiab tawv lossis nyuaj heev, qhov nyuaj ntawm ib hom pob zeb kuj tseem yuav txawv me ntsis, piv txwv li, limestone, sandstoneshale muaj limestone mos, limestone nruab nrab thiab limestone tawv, sandstone nruab nrab thiab sandstone tawv, thiab lwm yam.
Hauv qhov project drilling,Sab Hnub Tuaj Debmuaj 15 xyoo thiab ntau dua 30 lub tebchaws cov kev pabcuam kev paub los muab cov khoom siv laum thiab cov kev pabcuam drilling siab heev rau ntau yam kev siv sib txawv. Daim ntawv thov suav nrogkev khawb av thee, kev khawb tooj liab, hlau ore, cov hlau kubthiab lwm yam. Cov khoom siv laum ntau yam tuaj yeem hloov kho raws li cov pob zeb sib txawv vim peb muaj peb tus kheejAPI & ISOLub Hoobkas tau ntawv pov thawj ntawm cov khoom siv laum. Peb tuaj yeem muab peb tus engineer txoj kev daws teeb meem thaum koj tuaj yeem muab cov xwm txheej tshwj xeeb, xws liqhov nyuaj ntawm pob zeb, hom kev khawb rig, qhov ceev ntawm kev sib hloov, qhov hnyav ntawm qhov ntsis thiab torque.
