Momwe Opanga Migodi Otseguka ku Australia Amapezera Mano a ESCO Bucket Teeth Kuti Agwiritse Ntchito Zokumba Zovala Zosintha Mbali mu Ntchito za Iron Ore

Kwa aliyense amene wakhala nthawi yayitali akugwira ntchito yofufuza zitsulo ku Australia, chidebe chofukula ndi chimodzi mwa zizindikiro zooneka bwino kwambiri za momwe zipangizozi zikugwirira ntchito molimbika. Wogwira ntchito ya migodi waluso amayang'ana mano a chidebe ngati dokotala akuyang'ana zizindikiro zofunika kwambiri - kuchuluka kwa kuwonongeka kumakuuzani zonse zokhudza zomwe zikuchitika pathanthwe, ndipo kulephera kwa mano mosayembekezereka ndi chimodzi mwa zochitika zosokoneza kwambiri mu migodi.

Kudera la Pilbara ku Western Australia, komwe ndagwira ntchito ndi makontrakitala a migodi ndi oyang'anira zida kwa zaka zambiri, momwe mano a ndowa amagwirira ntchito pa zokumba matani 300 mpaka 800 pogwiritsa ntchito zitsulo zachitsulo ndi vuto lalikulu pakugwira ntchito komanso zachuma. Makinawa amasuntha zinthu zambiri zodabwitsa - chokumba chimodzi chachikulu mu ntchito yachitsulo ku Australia chimatha kusintha matani 10,000-15,000 patsiku - ndipo mtengo wa nthawi yosayembekezereka yogwira ntchito umafika pa madola masauzande ambiri pa ola limodzi.

Ichi ndichifukwa chake funso loti mungapeze bwanji mano enieni a ESCO - kapena ofanana ndi omwe agulitsidwa pamsika - ndilofunika kwambiri kwa akatswiri a migodi aku Australia. Nkhaniyi ndi chitsogozo chothandiza pamavuto opeza zinthu, cholembedwa kuchokera kwa munthu amene waona zotsatirapo zake chifukwa cholakwitsa. Malo Ogwirira Ntchito a Iron Ore ku Australia: Chifukwa Chake Magwiridwe Abwino a Mano a Bucket Ndi Ofunika Kwambiri

Musanaphunzire zambiri zokhudza kusaka, ndikofunikira kumvetsetsa chifukwa chake malo ogwirira ntchito achitsulo ku Australia amafunikira kwambiri mano a ndowa. Izi zimapanga mbali iliyonse ya chisankho chosaka.

Miyala yachitsulo ya ku Australia ku Hamersley Basin (chigawo chachikulu cha chitsulo chachitsulo ku Pilbara) imakhala ndi miyala ya hematite yokhala ndi Banded Iron Formation (BIF) ndi miyala ya martite-goethite. Izi ndi zina mwa zinthu zomwe zimayamwa kwambiri pakupanga migodi pamwamba pa nthaka - kuchuluka kwa silika mu miyala ya host, kuphatikiza ndi mineralization ya hematite yolimba, kumapangitsa kuti malo owonongeka azikhala amphamvu kwambiri kuposa avareji yapadziko lonse lapansi ya migodi yachitsulo.Chipinda cha Migodi cha Pilbarayafalitsa deta yomwe ikusonyeza kuti nthawi yozungulira yobowola ndi kuphulika ndi maola 2-3 ndipo nthawi yozungulira yokumba ndi masekondi 20-35 pa chidebe chilichonse, ndipo chidebe chilichonse chimanyamula matani 40-80 a zinthu.

Munthawi imeneyi, mano a ndowa si zinthu zongogwiritsidwa ntchito zokha - ndi zinthu zofunika kwambiri zomwe zimagwira ntchito zomwe zimatsimikizira mwachindunji mtengo pa tani imodzi ya zinthu zomwe zasunthidwa.
