Ukuqaliswa Okuyimpumelelo Kwephrojekthi Ye-2700 Ton I-Ultra-large Electric Ifosholo Synchronous Lifting Lifting Project e-Mongolia

Imayini yethusi ye-Oyu Tolgoi (iMayini ye-OT) ingenye yezimayini zethusi ezinkulu kakhulu emhlabeni kanye nensika ebalulekile yezomnotho yaseMongolia. I-Rio Tinto kanye nohulumeni waseMongolia banamasheya angu-66% kanye nama-34% ngokulandelana. Ikhopha negolide ekhiqizwa imayini yethusi yenza ama-30% kuya ku-40% e-GDP yaseMongolia. Imayini ye-OT iqhele ngamakhilomitha angama-80 ukusuka emngceleni ophakathi kweChina neMongolia. Kusukela ngoJulayi 2013, kancane kancane iye yathumela impushana yethusi e-China. Into esemqoka kule phrojekthi udondolo olukhulu kulo mhlaba: ifosholo likagesi.

Ingemuva lephrojekthi

Ifosholo likagesi lingenye yezinto ezisetshenziswa kakhulu zezimayini emayini yomgodi ovulekile ongamathani ayizigidi eziyi-10. Inokukhiqiza okuphezulu, izinga eliphezulu lokusebenza kanye nezindleko eziphansi zokusebenza. Kuyimodeli eyaziwayo embonini yezimayini. Ifosholo likagesi liqukethe idivayisi egijimayo, idivayisi ejikelezayo, idivayisi esebenzayo, isistimu yokugcoba, kanye nesistimu yokuhlinzeka ngegesi. Ibhakede liyingxenye eyinhloko yefosholo likagesi. Ithwala ngokuqondile amandla ensimbi embiwe ngakho-ke iyagqokwa. Induku futhi ingenye yezingxenye eziyinhloko ohlelweni lokumba. Umsebenzi wayo ukuxhuma nokusekela ibhakede, nokudlulisa isenzo sokuphusha ebhakedeni. Ibhakede lenza isenzo sokumba inhlabathi ngaphansi kwesenzo esihlangene sokusunduza nokuphakamisa amandla; umshini wokukhasa oyinhloko endleleni yokuhamba ekugcineni ulenza lihambe liqonde phansi ngendlela yokudlulisela ehlobene.

Kodwa-ke, emsebenzini wansuku zonke, ifosholo likagesi elikhulu kakhulu elinesisindo samathani angu-2,700 kudingeka lilungiswe kabusha njalo ukuze kuqinisekiswe ukuqhubeka kokuhlela.

Ubunzima

Entweni enjalo enkulu futhi eqinile, lapho ushintsha izingxenye ezifana nemishini yokuhamba yesiseshi nemishini ezungezisayo, kuyadingeka ukuphakamisa wonke umshini ngokuvumelana, futhi phezulu okubushelelezi kungafinyelela ubude obuthile ukuze kube lula ukunakekelwa kwesayithi. Ungaqinisekisa kanjani ukuthi ukwakheka kwawo wonke umshini awonakali, nokuthi kungalinganiswa futhi?

Isixazululo

Ithimba lezobuchwepheshe le-Canete lixhumane kaningi nomnyango wokulungisa imayini ye-OT, futhi lahlaziya amandla ngendlela ehlelekile. Okokugcina, kuyaqinisekiswa ukuthi umkhiqizo onelungelo lobunikazi owenziwe i-Canete-PLC multi-point synchronous jacking hydraulic system isetshenziselwa ukulawula i-servo yamaphoyinti angu-10.

Inhloso ukusabalalisa ifosholo elikhulu likagesi endaweni ezindaweni zokucindezeleka ezingu-10, ezingu-6 zazo zisekelwe ngamathani angu-600 amathani angu-180mm ojekhi behydraulic amathani amakhulu, kanti amanye amaphuzu angu-4 athatha amathani angu-200 we-1800mm hydraulic jacks. Ngokulawulwa kwe-loop evaliwe kabili yokufuduka kanye nokucindezela kwama-jacks ayi-10, inkinga yokuvumelanisa ukufuduka kanye nokulingana kokucindezeleka ensimini iyaxazululwa.

Iphrojekthi Compukukhululwa

Iphrojekthi isiqedile umsebenzi wokulungisa ngoMeyi 5, 2019. Ngokusho kokuqaliswa okuqondile kwesayithi, ukunemba kokufuduka kulawulwa ku-0.2mm esimweni sokuxazulula ibhalansi yokucindezeleka, futhi ekugcineni kuhlangabezana nezidingo zobuchwepheshe.
