Nyob rau xyoo 1982, thaj tsam ntawm Taibu mining tau txais tos loj - cov tsheb loj thauj khoom nruab nrog Cummins KTA50 cav. Nov yog thawj zaug Cummins cov khoom nkag mus rau qhov qhib no - qhov kuv. Lub sijhawm ntawd, ntau tshaj 20 tus kws tshaj lij, cov kws tshaj lij kho dua tshiab, thiab cov kws tshaj lij ntawm Tebchaws Meskas, Tebchaws Askiv, Australia, thiab lwm qhov chaw tau hla dej hiav txwv los coj kev ruaj khov ntawm cov khoom siv ntawm Tuam Tshoj Coal Pingshuo.
Xyoo 2005, pab pawg pabcuam hauv Suav teb tau tuav lub luag haujlwm ntawm kev tiv thaiv. Raws li kev txuas ntxiv ntawm kev pabcuam, lawv nquag mus tob rau hauv kev ua haujlwm ntawm cov kab pem hauv ntej kom kho cov phiaj xwm kev lag luam thiab kev saib xyuas zoo rau cov neeg siv khoom.
Tam sim no, cov cav tseem ceeb hauv cheeb tsam mining tau ua tiav nkag mus rau "lub sijhawm thib plaub loj dua tshiab". Txhawm rau kom ntseeg tau tias cov khoom sib dhos ntawm thaj chaw mining thiab txhim khu kev lag luam ntawm cov cuab yeej siv, Cummins tau tsim kho tshiab "rov kho dua tshiab" txoj kev npaj.
Kev kho dua tshiab tsis kho; nws yog "rebirth".
Nkag mus rau lub voj voog thib plaub, cov khoom tseem ceeb ntawm cov tshuab mus txog qhov tseem ceeb ntawm kev saib xyuas tob. Cummins, ua ke nrog cov kev ua haujlwm tiag tiag ntawm Tuam Tshoj Coal Pingshuo, tsim kho tshiab "kev kho dua tshiab" txoj kev npaj - los ntawm cov khoom siv hloov pauv, thawj lub Hoobkas txheej txheem sib dhos, mus rau tag nrho - lub tshuab thauj khoom, tag nrho cov txheej txheem yog benchmarked tawm tsam lub Hoobkas qauv ntawm cov tshuab tshiab. Txhua lub tshuab refurbished raug tshuaj xyuas kom meej ua ntej tawm hauv lub Hoobkas, nrog rau lub zog tsis muaj zog thiab tshem tawm tag nrho raws li cov kev xav tau ntawm cov tshuab tshiab, kom ntseeg tau ntev - lub sijhawm thiab txhim khu kev lag luam hauv hnyav -load mining tej yam kev mob.
Txoj kev npaj kho dua tshiab tau tsim los ntawm Cummins tau daws peb cov teeb meem ceev. Cov refurbished xyaw no tau ua hauj lwm ntawm tag nrho cov load rau lub sij hawm ntev, thiab cov mining ntau lawm atherosclerosis yog tsis muaj kev cuam tshuam los ntawm cov khoom ua tsis tau tejyam. Ob qhov teeb meem loj ntawm kev siv nyiaj txiag thiab kev pheej hmoo ntawm kev tsim khoom tau raug daws ib txhij.
Original Hoobkas qauv, tsis muaj qhov zoo downgrade.
Kev sib koom ua haujlwm ntawm cov cuab yeej siv thiab cov phiaj xwm tsim khoom txhua xyoo, Cummins tau tsim kho cov txheej txheem kev tshawb fawb txog kev nkag mus rau Tuam Tshoj Coal Pingshuo, tsim nyog npaj cov kev kho kom zoo dua qub, ua kom cov cuab yeej tu thiab cov phiaj xwm ntau lawm synchronized. Thoob plaws hauv cov txheej txheem kho dua tshiab, cov khoom siv ntshiab tau siv, kom ntseeg tau qhov zoo ntawm kev kho dua tshiab los ntawm qhov chaw.
Raws li tam sim no, txoj kev npaj no tau ua tiav thiab ua tiav cov txiaj ntsig hauv thaj chaw Pingshuo mining ntawm Tuam Tshoj Coal: tag nrho ntawm 15 QSK60 lub cav tau kho dua tshiab thiab kho dua tshiab, nrog rau 6915% nce hauv cov xuab moos.
Nrog rau kev txhim kho txuas ntxiv ntawm txoj kev npaj kho dua tshiab, lub neej kev pab cuam ntawm cov khoom siv tseem ceeb hauv cheeb tsam mining tau txuas ntxiv mus. Qhov no tsis yog tsuas yog ua kom ntseeg tau cov khoom siv txhim khu kev qha, tab sis kuj tseem pab cov neeg siv khoom txuag cov nqi khoom, txo tus nqi tu, thiab txhim kho tus nqi tuaj koom, ua tiav cov nqi optimization thoob plaws hauv lub neej.
Lub xoom loj tsis ua hauj lwm cov ntaub ntawv ntawm cov refurbished machines uas tau siv nyob rau hauv ob lub xyoos dhau los tag nrho validates cov kev ntseeg tau thiab economic feasibility ntawm Cummins refurbishment txoj kev npaj. Peb paub zoo txog Cummins ' customized mining fais fab kev pabcuam kho dua tshiab.
Cov khoom siv muaj lub voj voog, tab sis kev pabcuam tsis muaj qhov kawg.
Tuam Tshoj Coal Pingshuo tau ua haujlwm nrog Cummins rau ntau tshaj 40 xyoo. Hauv qab qhov kev ntseeg siab yog kev txhawb nqa kev pab cuam lub neej tag nrho thoob plaws hauv ua ntej- muag thiab tom qab- muag. Pab neeg pabcuam nkag mus tob rau hauv cov kev ua haujlwm ntawm cov kab pem hauv ntej, sib txuas cov khoom siv tu vaj tse ntawm cov neeg siv khoom, thiab sib koom ua ke tsim cov kev tswj xyuas kev tshawb fawb thiab qib siab - cov txheej txheem kho dua tshiab, txo cov khoom siv poob qis los ntawm qhov chaw.
Nyob rau tib lub sijhawm, cov kws tshaj lij pabcuam tau nyob hauv thaj chaw mining, hu rau 7 × 24 teev. Nrog rau kev txawj ntse zoo thiab kev paub nplua nuj, cov khoom siv xav tau raug kho tam sim ntawd, cov teeb meem raug daws sai, ua kom cov mining efficiency.
Tsis tas li ntawd, Cummins tseem koom tes nrog cov neeg siv khoom ntawm - qhov chaw khaws thiab npaj cov khoom seem, ua raws qhov xav tau thiab muab cov khoom siv raws sijhawm. Cov saw dav dav ntawm kev tsim kho, ntawm -qhov chaw teb, thiab cov kev pabcuam taug qab txhua hnub muab kev pabcuam sijhawm ntev thiab ruaj khov rau kev tsim khoom ntawm Tuam Tshoj Coal Pingshuo.
