Mgodi wa Oyu Tolgoi Copper (OT Mine) ndi umodzi mwa migodi yamkuwa yayikulu kwambiri padziko lonse lapansi komanso mzati wofunikira wachuma ku Mongolia. Rio Tinto ndi boma la Mongolia ali ndi 66% ndi 34% ya magawo motsatana. Mkuwa ndi golide wopangidwa ndi mgodi wa mkuwa umapanga 30% mpaka 40% ya GDP ya Mongolia. Mgodi wa OT uli pamtunda wa makilomita pafupifupi 80 kuchokera kumalire a China ndi Mongolia. Kuyambira Julayi 2013, idatumiza pang'onopang'ono ufa wabwino wamkuwa ku China. Chinthu chachikulu chozungulira polojekitiyi ndi chimphona chachikulu padzikoli: fosholo yamagetsi.
Mbiri ya Ntchito
Fosholo yamagetsi ndi imodzi mwa zida zazikulu zamigodi mu mgodi wotseguka wa matani 10 miliyoni. Ili ndi zokolola zambiri, kuchuluka kwa magwiridwe antchito komanso kutsika mtengo. Ndi chitsanzo chodziwika mumakampani amigodi. Fosholo yamagetsi imakhala ndi chipangizo choyendetsa, chipangizo chozungulira, chipangizo chogwirira ntchito, makina opangira mafuta, ndi makina opangira gasi. Chidebe ndicho chigawo chachikulu cha fosholo yamagetsi. Imanyamula mwachindunji mphamvu ya miyala yofukulidwayo ndipo imavalidwa. Ndodo imakhalanso imodzi mwa zigawo zikuluzikulu za ntchito yofukula. Ntchito yake ndikugwirizanitsa ndi kuthandizira chidebecho, ndi kufalitsa zochita zokankhira ku ndowa. Chidebecho chimachita ntchito yofukula nthaka pansi pa kukakamiza ndi kukweza mphamvu; chida chachikulu kwambiri chokwawa pamakina oyendayenda pamapeto pake chimapangitsa kuti chisunthike pansi kudzera pamakina ofananirako.
Komabe, pa ntchito ya tsiku ndi tsiku, fosholo yamagetsi yokulirapo yolemera matani 2,700 iyenera kukonzedwanso pafupipafupi kuti zitsimikizire kupitirizabe kukonzekera.
Zovuta
Kwa chinthu chachikulu komanso cholimba chotere, posintha zinthu monga zida zoyenda zokwawa ndi zida zozungulira, ndikofunikira kukweza makina onse molumikizana bwino, ndipo pamwamba pake yosalala imatha kufikira kutalika kwina kuti athandizire kukonza pamalopo. Kodi mungatsimikizire bwanji kuti makina onsewo asawonongeke, komanso kuti atha kukhala oyenera?
Yankho
Gulu laukadaulo la Canete lalankhulana mobwerezabwereza ndi dipatimenti yokonza migodi ya OT, ndikusanthula mwadongosolo mphamvu. Pomaliza, zimatsimikiziridwa kuti chinthu chovomerezeka chopangidwa ndi Canete-PLC multi-point synchronous jacking hydraulic system chimagwiritsidwa ntchito pakuwongolera 10-point servo.
Cholinga chake ndi kugawira fosholo yamagetsi kumadera 10 opsinjika, 6 omwe amathandizidwa ndi matani 600 sitiroko 180mm yochita kawiri matani akuluakulu a jacks a hydraulic, ndipo mfundo zina 4 zimatenga matani 200 a jacks a hydraulic 1800mm. Kupyolera muulamuliro wotsekedwa kawiri wa kusamuka ndi kukakamizidwa kwa ma jacks 10, vuto la kugwirizanitsa kusamuka komanso kugwirizanitsa maganizo m'munda kumathetsedwa.
Project Completion
Ntchitoyi yatsiriza ntchito yokonza pa May 5, 2019. Malingana ndi kukhazikitsidwa kwapadera kwa malowa, kulondola kwa kusamuka kumayendetsedwa ku 0.2mm pothetsa kupsinjika maganizo, ndipo potsiriza kumakwaniritsa zofunikira zaumisiri.
Nthawi yotumiza: May-15-2019
