I-Oyu Tolgoi Copper Mine (i-OT Mine) yenye yeemayini zethusi ezinkulu kwihlabathi kunye nentsika ebalulekileyo yezoqoqosho eMongolia. I-Rio Tinto kunye norhulumente waseMongolia babambe i-66% kunye ne-34% yezabelo ngokulandelelanayo. Ubhedu kunye negolide eveliswa ngumgodi wobhedu i-akhawunti ye-30% ukuya kwi-40% ye-GDP yaseMongolia. Umgodi we-OT umalunga neekhilomitha ezingama-80 ukusuka kumda ophakathi kweTshayina neMongolia. Ukusukela ngoJulayi 2013, ithe chu ngokuthe ngcembe ithumela umgubo wobhedu eTshayina. Eyona nto iphambili kule projekthi sisigebenga esikhulu kulo mhlaba: ifotsholo yombane.
Imvelaphi yeProjekthi
Umhlakulo wombane sesinye sezixhobo eziphambili zemigodi kumgodi ovulekileyo oziitoni ezili-10. Inemveliso ephezulu, izinga eliphezulu lokusebenza kunye neendleko zokusebenza eziphantsi. Yimodeli eyaziwayo kwishishini lezemigodi. Ifosholo yombane inesixhobo esisebenzayo, isixhobo esijikelezayo, isixhobo esisebenzayo, inkqubo yokuthambisa, kunye nenkqubo yokubonelela ngegesi. Ibhakethi licandelo eliphambili lefotsholo yombane. Ithwala ngokuthe ngqo amandla e-ore egrunjiweyo kwaye ngoko iyanxitywa. Ukhuni lukwayenye yezinto eziphambili kwinkqubo yokomba. Umsebenzi wayo kukudibanisa kunye nokuxhasa ibhakethi, kunye nokudlulisa isenzo sokutyhala kwibhakethi. Ibhakethi lenza isenzo sokumba umhlaba phantsi kwesenzo esidibeneyo sokutyhala kunye nokuphakamisa amandla; esona sixhobo singundoqo sokukhasa kwindlela yokuhamba ekugqibeleni siyenza ihambe ngokuthe ngqo emhlabeni ngendlela yothumelo enxulumeneyo.
Nangona kunjalo, kumsebenzi wemihla ngemihla, ifosholo yombane enkulu kakhulu enobunzima beetoni ezingama-2,700 kufuneka ihlaziywe rhoqo ukuze kuqinisekiswe ukuqhubeka kwesicwangciso.
Ubunzima
Kwinto enjalo enkulu kwaye eqinile, xa utshintshela amacandelo afana nezixhobo zokuhamba ezihamba nge-crawler kunye nezixhobo ezijikelezayo, kuyimfuneko ukuphakamisa umatshini wonke ngokuhambelanayo, kwaye umphezulu ogudileyo unokufikelela kubude obuthile ukuququzelela ukugcinwa kwendawo. Indlela yokuqinisekisa ukuba isakhiwo somatshini wonke asonakaliswa, kwaye sinokulungelelaniswa kwakhona?
Isisombululo
Iqela lobuchwephesha beCanete linxibelelane ngokuphindaphindiweyo nesebe lokugcinwa komgodi we-OT, kwaye lahlalutya ngokucwangcisiweyo amandla. Ekugqibeleni, kuqinisekiswa ukuba imveliso enelungelo lobunikazi eyenziwe yi-Canete-PLC ye-multi-point synchronous jacking system ye-hydraulic isetyenziselwa ukulawula i-servo ye-10.
Injongo kukusasaza ifotsholo enkulu yombane kwindawo yeendawo ezili-10 zoxinzelelo, ezi-6 zazo zixhaswa yi-600 ton stroke 180mm ezisebenza kabini iitoni ezinkulu ze-hydraulic jacks, kwaye ezinye iingongoma ezi-4 zithatha i-200 ton stroke ye-1800mm hydraulic jacks. Ngokusebenzisa i-double-loop-loop control of displacement kunye noxinzelelo lwee-jacks ze-10, ingxaki yokulungelelaniswa kwe-displacement kunye nokulingana koxinzelelo kwintsimi ixazululwe.
Iprojekthi Compukwazisa
Iprojekthi igqibe umsebenzi wokugcinwa kwe-5 ngoMeyi 2019. Ngokokuphunyezwa okuthe ngqo kwesiza, ukuchaneka kokufuduka kulawulwa kwi-0.2mm kwimeko yokusombulula ibhalansi yoxinzelelo, kwaye ekugqibeleni ihlangabezana neemfuno zobugcisa.
