Lub Oyu Tolgoi tooj liab Mine (OT Mine) yog ib qho ntawm cov tooj liab loj tshaj plaws hauv ntiaj teb thiab yog ib qho tseem ceeb ntawm kev lag luam ntawm Mongolia. Rio Tinto thiab tsoom fwv Mongolian tuav 66% thiab 34% ntawm feem. Cov tooj liab thiab kub ua los ntawm tooj liab mine account rau 30% mus rau 40% ntawm Mongolia GDP. Lub OT mine yog li 80 mais deb ntawm ciam teb ntawm Tuam Tshoj thiab Mongolia. Txij li thaum Lub Xya Hli 2013, nws tau maj mam xa tawm tooj liab zoo hmoov rau Tuam Tshoj. Qhov loj tshaj plaws nyob ib ncig ntawm qhov project no yog super loj heev ntawm thaj av no: hluav taws xob shovel.
Qhov project Background
Lub tshuab hluav taws xob yog ib qho ntawm cov khoom siv mining tseem ceeb hauv 10 lab-tuj qhib-qhov mine. Nws muaj cov khoom lag luam siab, kev ua haujlwm siab thiab kev ua haujlwm qis. Nws yog tus qauv lees paub hauv kev lag luam mining. Lub tshuab hluav taws xob muaj cov khoom siv khiav, lub tshuab tig, cov cuab yeej ua haujlwm, lub tshuab lubrication, thiab cov khoom siv roj. Lub thoob yog qhov tseem ceeb ntawm lub tshuab hluav taws xob. Nws ncaj qha bears lub zog ntawm excavated ore thiab yog li ntawd hnav. Tus pas kuj yog ib qho ntawm cov khoom tseem ceeb hauv cov txheej txheem excavation. Nws txoj haujlwm yog txuas thiab txhawb nqa lub thoob, thiab xa cov kev thawb mus rau lub thoob. Lub thoob ua qhov kev txiav txim ntawm kev khawb av nyob rau hauv kev sib xyaw ua ke ntawm kev thawb thiab nqa quab yuam; qhov tseem ceeb tshaj plaws crawler ntaus ntawv nyob rau hauv lub mus txawv tebchaws mechanism nws thiaj li ua rau nws txav ncaj qha rau hauv av los ntawm lwm yam kis mechanism.
Txawm li cas los xij, hauv kev ua haujlwm txhua hnub, lub zog hluav taws xob loj dua qhov hnyav 2,700 tons yuav tsum tau hloov kho tsis tu ncua kom ntseeg tau tias kev npaj txuas ntxiv mus.
Nyuaj
Rau xws li cov khoom loj thiab nruj, thaum hloov cov khoom xws li crawler taug kev cov cuab yeej thiab cov cuab yeej tig, nws yog ib qho tsim nyog los tsa lub tshuab tag nrho synchronously, thiab cov saum npoo du tuaj yeem ncav cuag qhov siab los pab txhawb kev txij nkawm ntawm qhov chaw. Yuav ua li cas kom paub meej tias cov qauv ntawm tag nrho lub tshuab tsis puas, thiab nws tuaj yeem sib npaug?
Kev daws
Pab pawg kws tshaj lij Canete tau rov sib txuas lus nrog OT mine lub chaw saib xyuas, thiab tau tshuaj xyuas lub zog. Thaum kawg, nws tau lees paub tias cov khoom lag luam patented tsim los ntawm Canete-PLC multi-point synchronous jacking hydraulic system yog siv rau 10-point servo tswj.
Lub hom phiaj yog txhawm rau faib cov hluav taws xob loj hauv zos rau 10 cov ntsiab lus kev ntxhov siab, 6 ntawm cov uas tau txais kev txhawb nqa los ntawm 600 tuj stroke 180mm ob-ua yeeb yam loj-tonnage hydraulic jacks, thiab lwm yam 4 ntsiab lus txais 200 tuj stroke ntawm 1800mm hydraulic jacks. Los ntawm ob lub voj kaw kaw ntawm kev hloov pauv thiab siab ntawm 10 jacks, qhov teeb meem ntawm kev xaav synchronization thiab kev ntxhov siab sib npaug hauv thaj teb tau daws.
Qhov project Compkev cia siab
Lub phiaj xwm tau ua tiav cov haujlwm txij nkawm thaum lub Tsib Hlis 5, 2019. Raws li qhov tshwj xeeb kev siv ntawm qhov chaw, qhov raug tshem tawm raug tswj kom 0.2 hli nyob rau hauv cov ntaub ntawv ntawm kev daws qhov kev ntxhov siab, thiab thaum kawg ua tau raws li cov kev cai.
