(7) Raws li hom cab, nws muab faib ua AC hoisting khoom thiab DC hoisting khoom.
3) Hoisting system
(1) Ib txoj hlua winding hoisting ntawm tus ncej
Rau cov mines nrog qhov tob tob tsawg dua 300m thiab nruas txoj kab uas hla tsis tshaj 3m, nws yog ib qho tsim nyog yuav tau txais ib txoj hlua winding hoisting system. Xaiv lub tawb lossis hla raws li lub thawv hoisting yog ib qho teeb meem tseem ceeb hauv kev tsim, uas yuav tsum tau txiav txim siab los ntawm kev sib piv ntawm ntau yam (ntau txoj hlua sib txhuam hoisting yog tib yam).
Feem ntau nyob rau hauv kev tsim ntawm lub hoisting system, ob txheej ntawm cov khoom siv hoisting yog siv los xyuas kom meej lub mine tso zis thiab ua kom tiav lwm yam lifting hauj lwm. Lub qhov dej tseem ceeb yog hla mus nqa cov ore, thiab lub qhov dej pabcuam yog tawb kom ua tiav cov haujlwm pabcuam hoisting lossis lub ntsiab thiab lub qhov dej pabcuam yog txhua lub tawb. Txoj kev twg yuav tsum tau txiav txim siab raws li cov xwm txheej tshwj xeeb ntawm txhua qhov mine. Thaum cov khoom tsim tawm txhua xyoo ntawm cov mine yog qhov loj, nws yog qhov zoo tshaj plaws los siv lub ntsiab ncej hla, pab pawg ncej tawb thaum lub xyoo tso tawm ntawm lub mine me me los yog hom ore ntau tshaj ob hom, los yog cov ore tsis tsim nyog. crushed, nws yog qhov zoo tshaj plaws los siv lub tawb.
Thaum ntau qib nce, qhov sib npaug rauj ib lub tawb feem ntau yog siv los nce hauv cov mines qhov twg cov txiaj ntsig tsis loj heev thiab qib kev txhim kho ntau dua, thiab qee zaum ob pawg sib npaug rauj ib lub tawb yog siv los xyuas kom muaj txiaj ntsig.
Rau cov mines uas muaj cov khoom tsim tawm txhua xyoo me me, cov cuab yeej siv lub tawb nqa tuaj yeem siv los ua kom tiav tag nrho cov haujlwm nqa. Qhov no yog qhov tseeb ntawm ntau cov mines uas tsis yog-ferrous hlau, cov mines tsis yog xim hlau thiab cov mines nuclear hauv Suav teb.
(2) Ncej ntau txoj hlua sib txhuam hoisting
Multi-rope kev sib txhuam of elevator muaj ntau yam zoo. Yog li ntawd, ntxiv nrog rau ntau txoj hlua kev sib txhuam ntawm lub elevator thaum lub qhov tob tob tshaj 300m es tsis txhob ntawm lub nruas txoj kab uas hla ntau tshaj 3m, ib tug me me txoj hlua sib txhuam of elevator kuj siv tau los hloov ib txoj hlua winding of elevator nrog lub nruas. txoj kab uas hla tsawg dua 3 m.
Txij li thaum nws yog ib qho nyuaj los kho cov hlua hlua ntev, ob lub thawv nqa tsuas yog tsim rau ib qib ntau lawm. Nyob rau tib lub sijhawm, vim muaj kev cuam tshuam ntawm kev deformation ntawm txoj hlua nqa hlua, ob lub thawv hoisting system tuaj yeem tsuas yog xyuas kom meej qhov chaw nres tsheb ntawm lub qhov dej hauv qhov kev ua haujlwm tiag tiag, thiab lub thawv rau hauv qab ntawm lub qhov dej yog nres hauv qhov chaw nres tsheb. txoj hauj lwm meej (rau kev hla hoisting, qhov tseeb ntawm qhov chaw nres tsheb tsis nruj).
Ib lub thawv sib npaug rauj hoisting system tshwj xeeb tshaj yog tsim rau ntau qib hoisting mines. Thiab qhov sib npaug rauj nqa tuaj yeem txhim kho kev ua haujlwm ntawm kev sib txhuam ntawm ntau txoj hlua hoisting system. Ntxiv mus, ib lub thawv hoisting system tsis cuam tshuam los ntawm kev deformation ntawm cov hlua hlau, uas tuaj yeem ua kom qhov chaw nres tsheb raug ntawm txhua qib ntau lawm, yog li nws siv ntau dua. Rau ntau theem kev txhim kho nrog ntau tshaj ob hom ore, ob txheej ntawm ib lub thawv hoisting khoom thiab ib txheej ntawm ib lub thawv raws li qhov xav tau ntawm cov khoom tsim tshwj xeeb thiab qib ntau lawm.
(3) Slope ncej hoisting
Kev txhawb nqa ncej inclined muaj qhov zoo ntawm kev tsim kho sai thiab kev nqis peev tsawg. Nws qhov tsis zoo yog tias qhov hoisting ceev qeeb, tshwj xeeb tshaj yog thaum qhov ntev inclined loj, lub peev xwm ntau lawm yog me me, cov hlua hlau hnav yog loj, thiab tus nqi tu qhov dej zoo yog siab. Yog li ntawd, inclined ncej hoisting feem ntau yog siv nyob rau hauv me me thiab nruab nrab mines (tshwj tsis yog siv conveyor hoisting).
Lub hoisting yog muab faib ua ob hom: ib tug nuv thiab ob tug nuv. Qhov zoo ntawm kev txhim kho ib qho kev sib txuas tsuas yog cov ncej me me, kev nqis peev tsawg, tus nqi tu qis thiab kev txhim kho ntau theem yooj yim. Qhov tsis zoo yog qhov muaj peev xwm ntau lawm thiab kev siv hluav taws xob siab. Qhov zoo ntawm kev txhim kho ntawm ob qhov sib txuas mine tsheb yog cov khoom siv loj thiab kev siv hluav taws xob me me, xws li cov ncej loj, kev thauj khoom nyuaj thiab kev thauj mus los, kev nqis peev ntau dua, uas tsis zoo rau kev txhim kho ntau theem. Feem ntau, thaum lub tsheb sib txuas ib leeg yog siv los ua kom tau raws li qhov yuav tsum tau ua, ob chav sib txuas tsis siv.
Vim muaj kev nqis peev loj thiab siv sijhawm ntev, thaum lub inclined ncej inclination tsawg dua 28 °, cov mining tsheb pab pawg yuav tsum tau saws kom deb li deb tau. Txawm li cas los xij, qhov tso cai ceev ntawm inclined ncej hla hoisting yog qhov loj thiab lub sijhawm nres tsheb yog luv. Yog li ntawd, nyob rau hauv mine nrog loj txhua xyoo tso zis, tsis muaj qhov luaj li cas ntawm lub inclination lub kaum sab xis. Txawm li cas los xij, thaum qhov inclination tsawg dua 18 °, txoj siv conveyor kuj tseem siv tau.
4) Rov qab cov ntxhia hmoov
Cov ncej hla hoisting yog vim cov ore filling, ore filling los yog dej seepage ntawm cov ore, cov nplua ore los yog av nkos thiab dej sib tov, thiab xau mus rau hauv qab ntawm lub qhov dej los ntawm lub rooj vag sib txawv, tsim ib tug loj npaum li cas ntawm slurry. , ua rau cov pob zeb nplua nuj nyob hauv qab ntawm qhov dej. Ntxiv nrog rau kev siv cov kev ntsuas zoo los txo cov peev txheej ntawm cov nplua ore, cov khoom siv zoo ore rov qab yuav tsum tau tsim. General zoo hmoov ore rov qab txoj kev muaj ntau yam hauv qab no.
(1) Siv lub hauv qab ntawm lub qhov dej raws li cov hmoov bunker, pib los ntawm qhov qis tshaj tawm ntawm cov ncej, khawb txoj kev nrog lub tawb me me mine ncej) nyob rau hauv qab ntawm lub hlais zoo. Tom qab cov hmoov zoo yog loaded los ntawm lub qhov rooj funnel, nws yog lifted thiab unloaded los ntawm lub me tawb (los yog lub me me inclined zoo) rau hauv lub hla bunker.
(2) Thaum cov khoom sib tov tau txais, cov hmoov ore warehouse yog teem rau hauv qab ntawm lub qhov dej, los ntawm lub hauv qab tank tawb mus rau lub tsheb, thiab txuas nrog lub loading chaw nres nkoj ntawm hmoov ore warehouse nrog rau sab channel. Tom qab cov hmoov ore loaded, lub tank yog lifted, unloaded mus rau hauv lub hla kuv warehouse los yog ncaj qha nce saum npoo.
(3) Thaum lub ntsiab thiab lub qhov dej pab cuam kaw, lub qhov dej pabcuam yog ib theem ua ntej ntawm nws. Tom qab cov ore zoo yog loaded los ntawm lub hauv qab hmoov mine warehouse ntawm lub ntsiab qhov dej, lub auxiliary ncej yog lifted thiab unloaded rau hauv lub hla kuv warehouse, los yog ncaj qha nce saum npoo.
Ntawm cov saum toj no peb txoj kev, thawj txoj kev muaj qhov loj tshaj plaws ntawm kev loj hlob thiab kev tswj tsis yooj yim, tab sis nws tuaj yeem zam qhov tsis zoo ntawm kev siv cov hlua khi hlua khi los yog txoj hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua khi hlua. bunker nyob rau hauv ob txoj kev tom kawg.
