LAC-Tuam Tshoj cov khoom lag luam yuav luag ruaj khov hauv 2020. Qhov no yog qhov tseem ceeb hauv nws tus kheej, vim LAC GDP poob ntau dua 7 feem pua hauv 2020 raws li IMF kwv yees, poob kev loj hlob ntawm kaum xyoo., thiab cov khoom xa tawm hauv cheeb tsam poob tag nrho (United Nations 2021).Txawm li cas los xij, vim kev lag luam ruaj khov nrog Tuam Tshoj thaum muaj kev lag luam poob qis, LAC cov khoom lag luam ntws nrog Tuam Tshoj tau nce mus rau qib ntawm GDP hauv cheeb tsam.
LAC cov khoom xa tawm mus rau Tuam Tshoj tau nce me ntsis los ntawm $ 135.2 nphom mus rau kwv yees li $ 135.6 nphom, thiab Tuam Tshoj cov khoom xa tawm mus rau LAC poob me ntsis los ntawm $ 161.3 nphom mus rau kwv yees $ 135.6 billion.$160.0 billion.Tab sis raws li LAC lub regional GDP poob qis heev, ob qho tib si ntshuam thiab xa tawm tau nce ntxiv raws li feem pua ntawm GDP, thiab qhov nyiaj tshuav tau nce me ntsis, los ntawm 0.5% mus rau 0.6% ntawm lub regional GDP.
Kev lag luam zoo li yuav pom qhov cuam tshuam ntawm kev hloov pauv txuas ntxiv hauv cov nqi hlau thaum lub ntiaj teb kev lag luam rov qab los thiab cov txiaj ntsig ntawm Tuam Tshoj txoj kev txhawb nqa ntawm kev tsim kho rov qab.Txawm hais tias cov nqi hlau tau nce xyoo 2020, Lub Tsev Haujlwm Saib Xyuas Kev Lag Luam thiab Lub Tuam Txhab Nyiaj Txiag Ntiaj Teb cia siab tias tus nqi hlau yuav poob dua nyob rau xyoo tom ntej, thaum qhov kev cia siab rau tooj liab yog qhov zoo dua.Qhov no yog xov xwm zoo rau kev xa tawm cov khoom siv tshuab mining los ntawm Tuam Tshoj mus rau Latin America, tshwj xeeb tshaj yog cov khoom siv drilling.Peb lub tuam txhab Hebei Gimarpal Machinery Technology Co., Ltd. yog tshwj xeeb hauv kev tsim thiab xa tawm cov cuab yeej mining drilling nrog tus kheej lub Hoobkas, xws li taper bar, threaded bar, chisel ntsis, khawm ntsis.Yog li ntawd, 2021 yuav yog lub sijhawm tshiab.
Ib hom kab noj hniav ua tau zoo volumetric qhov hauv qab fais fab tshuab, hu ua ntsia hlau laum.Cov ntsia hlau laum, uas siv cov av nkos thiab dej huv raws li lub zog nruab nrab, yog thauj mus rau hauv qab ntawm lub qhov los ntawm qhov chaw nruab nrab ntawm lub laum pas nrig, thiab yog qhov tseem ceeb ntawm lub zog hloov khoom siv uas hloov lub siab lub zog ntawm cov kua rau hauv lub zog siv tshuab. .Thaum lub sij hawm drilling, cov ntsia hlau laum ncaj qha tsav cov tub ntxhais raj thiab lub laum me ntsis txuas nrog lub tsav ncej nyob rau hauv qab ntawm lub qhov kom tig.Tag nrho cov hlua tho tsuas yog siv los ua ib qho channel rau kev xa cov kev ua haujlwm siab nruab nrab thiab tus pas nrig txhawb nqa lub txee torque ntawm lub laum me ntsis, thiab tsis tig.Piv nrog rau cov pa drilling, ntsia hlau drilling muaj ntau yam zoo, xws li txo qis laum pas nrig hnav thiab siab drilling ceev.Nws yog cov cuab yeej tseem ceeb rau drilling qhov taw qhia qhov thiab tau ua lub luag haujlwm hauv kev ua haujlwm ntawm drilling.
Xyoo 1955, Lub Tuam Txhab Tebchaws Meskas Christensen Mine Drilling Products Company tau pib tshawb fawb raws li txoj cai Moinuo, thiab nws yog thawj zaug ua tiav xyoo 1964, hu ua "Dana Drill";lub Soviet Union tau kawm tiav "convex" ntsia hlau xyaum nyob rau hauv thaum ntxov 1970s;Tuam Tshoj Lub Chaw Tshawb Fawb Kev Tshawb Fawb Technology ntawm Ministry of Mines tau ua tiav kev xyaum ua haujlwm nyob rau xyoo 1980s.Lub teb chaws uas tau tsim cov kev xyaum ua kom deb li deb suav nrog Tebchaws Meskas, Russia, Tuam Tshoj, thiab Lub Tebchaws Yelemees.
