Codelco kuyimitsa ntchito zomanga kumpoto

Mgodi wa mkuwa wa Codelco wolamulidwa ndi boma ku Chile adati Loweruka adzayimitsa ntchito yomanga kumpoto kwa dzikolo ndikuyesera kuti apitirize kupanga mgodi wa Chuquicamata pomwe akugwira ntchitoyo ndi ogwira ntchito.

Kampaniyo idanenanso kuti ikuchitapo kanthu kuti iteteze kufalikira kwa coronavirus boma litanena kuti kuchuluka kwa anthu omwe amafa chifukwa cha kachilomboka Loweruka koyambirira.

M'kati mwa kuyesetsa kukonzanso malipoti omwe amadzudzulidwa kwambiri okhudza kufa chifukwa cha kachilomboka, boma lidawonjezera chiwerengero cha anthu omwe amwalira mpaka 7,000 kuchokera pa 4,265 omwe adatsimikiziridwa kale.

Kulengeza kwa Codelco kudabwera patadutsa maola angapo pambuyo poti imfa yachiwiri yokhudzana ndi coronavirus ya wogwira ntchito ku Codelco itatsimikiziridwa.

Kampaniyo idati mgodi wake wa Chuquicamata, komwe imfa yoyamba ya coronavirus idachitika koyambirira kwa mwezi uno, ingogwira ntchito ndi anthu ochokera kutawuni yoyandikana nayo ya Calama kuti achepetse kufalikira kwa mliriwu.

"Kuyambira pano ogwira ntchito azibwera kuchokera ku Calama okha," adatero, ndikuwonjezera kuti "kuyesetsa kusungitsa kuchuluka kwa ntchito mumgodi."

Ntchito yomanga yomwe cholinga chake ndi kumaliza ntchito ya Chuquicamata Subterranea kumpoto kwa Chile idzayimitsidwa pomwe kampaniyo ikulitsa njira zake zolimbana ndi kachilomboka, adatero.

2. Maboti okonza mzere womaliza sangalole kuti matope a simenti akhale okwanira, koma amatha kuzungulira kapena kulowa ndikutuluka.
3. Mzere wa mphero nthawi zambiri umakhala wolunjika, muyenera kulabadira pakuyika, osasintha.
4. Kutalika kwa arc kwa ma circumferential slits onse sayenera kupitirira 310mm, ndipo chowonjezeracho chiyenera kumangidwa ndi mbale zachitsulo kuti chizipatula.
5. Kusiyana pakati pa zingwe zoyandikana sikuposa 3 ~ 9mm.
6. The interlayer iyenera kuikidwa molingana ndi zofunikira za mapangidwe pakati pa liner ndi mkati mwa pamwamba pa silinda. Ngati palibe chofunikira, matope a simenti okhala ndi mphamvu ya 42.5MPa akhoza kudzazidwa pakati pa awiriwo. Pambuyo pa matope a simenti, sunganinso mabawuti a liner.
7. Mukayika liner ndi mapepala a rabara, tsegulani pepala lophimbidwa 3 mpaka masabata a 4 musanayike kuti mulole kutambasula momasuka; Mukamagwiritsa ntchito pepala la rabara, mbali yayitali ya pepala la rabala iyenera kutsatira njira ya axial ya silinda, Mbali yaifupi imatsatira kuzungulira kwa silinda.
8. Yang'anani mosamala mabowo a bawuti ndi geometry ya mabawuti a liner, ndipo yeretsani mosamalitsa mabowo akung'anima, ma burrs, ndi ma protrusions pamabowo a bawuti a liner ndi mabawuti a liner kuti mabawulo athe kulowa momasuka pamalo ofunikira.

1. Musanakhazikitse zingwe zopangira mphero, muyenera kudziwa ma PC angati opangira mphero ayenera kusinthana.
2. Funsani katswiri kuti akonze ndikugwirizanitsa ndondomeko yonse yolowa m'malo. Zofunikira zonse zosinthira kutengera zojambula zantchito.
3. Ndikofunikira kuzungulira zamkati zotsala mu mphero ya mpira momwe mungathere, kuchotsa mphira wa rabara wa zinyalala, kuyeretsa malo otuluka pakhoma la mphero, ndikuchotsa fumbi ndikutsitsa silinda. Poyeretsa ntchitoyo, ndikofunikira kukonza mbiya ya mphero ya mpira. Malo ogwirira ntchito amafunika kukhala ndi mpweya wabwino komanso kutentha koyenera. Ndiye okhazikitsa akhoza kulowa mpira mphero mbiya kuyamba ntchito.
4. Mukachotsa zitsulo zakale za mphero, choyamba chotsani zomangira zomwe zagwiritsidwa ntchito, kenako chotsani mzere wakale wa mphero mzere umodzi pambuyo pa mzere umodzi, ndiyeno kwezani zitsulo zogwiritsidwa ntchito. Pochotsa chingwecho, munthuyo ayenera kumvetsera chitetezo ndikuyang'anitsitsa malo oima kuti asavulazidwe ndi mphero ya mpira.
5. Mzere watsopano wa mphero ya mpira uyenera kukhazikitsidwa kuti uwonetsetse kuti kusiyana pakati pa nthawiyo kuli mkati mwazofunikira. Konzani kuzungulira kwa liner ya mpira. Tsekani mosamala zonyamula ndi gasket kuti mupewe kutayikira kwa mchere wa ufa. Ngati palibe gasket, iyenera kukulungidwa mozungulira malo omwewo. Mizere iwiri ya thonje kapena hemp kuphatikiza mafuta otsogolera. Pa nthawi yomweyo, m`pofunika ntchito wosanjikiza matope simenti pa khoma lamkati ya silinda ndi wononga izo mwamphamvu pamaso kulimba. Tikumbukenso kuti mapeto opyapyala a sitepe liner ayenera mogwirizana ndi muvi molunjika pa kasinthasintha mphero.
6. Pambuyo m'malo, ndodo mphero mpira ayenera kutsimikizira kuti palibe munthu, palibe zida zogwirira ntchito, ndi zinthu zina zosafunikira mu yamphamvu, ndipo m'pofunika mosamala kuyang'ana mkati ndi kunja kwa silinda pamaso kutseka chopanda kanthu chivundikirocho.
