Ukwemba amatshe ensimbi kuhlala kuyimboni eyisisekelo emhlabeni wonke, okuhlanganisa ukukhiqizwa kwensimbi nokuthuthukiswa kwezinsiza. Ngokwanda kwesidingo samatshe ensimbi, izindlela eziphumelelayo zokwemba zibalulekile ukukhulisa umkhiqizo, ukwehlisa izindleko, nokunciphisa umthelela emvelweni. Lesi sihloko sihluza izindlela zakamuva zokwemba amatshe ensimbi, sigqamisa ukuthuthukiswa kobuchwepheshe, izifundo zangempela ezibandakanya indawo enkulu yeSimandou, namathiphu asebenzayo okwenza imisebenzi yokwemba ibe ngcono. Ngaphezu kwalokho, sithinta ukuthi izinkampani ezifana ne-广州市银鸥选矿科技有限公司 zibambisana kanjani ekwenzeni izinto ezintsha ekucubunguleni amaminerali.

Intsimbi yensimbi, impahla eluhlaza ebalulekile ekwenzeni insimbi, iyatholakala ngezindlela ezahlukene zokumba. Ukumba kuhilela ukuthola izinsimbi, ukukhipha intsimbi, nokuyicubungula ukuze kwenziwe izinto ezingasetshenziswa. Emhlabeni wonke, izimayela zensimbi ezibalulekile zifaka phakathi lezo zase-Australia, e-Brazil, kanye neSimandou range e-Guinea, okuyinto phakathi kwezinsiza ezinkulu zensimbi ezingakasetshenziswa. Ukuqonda izinto eziyisisekelo zokumba intsimbi yensimbi kusungula isisekelo sokwazisa izindlela ezithuthukile ezithuthukisa ukusebenza kahle nokusimama.

Ukwemba insimbi ngokuvamile kuqala ngokuhlola, okulandelwa ukulungiswa kwendawo, ukugruba, ukuqhuma, nokuthutha. Ins simbi bese igaywa, ihlungwe, futhi icutshungulwe ukuze kukhishwe insimbi eyigugu. Lezi zinyathelo kumele ziphathwe ngokucophelela ukuze kutholwe okuningi futhi kuncishiswe izindleko zokusebenza. Ukucatshangelwa kwezemvelo njengokuphathwa kukadoti nokubuyiselwa komhlaba nakho kuyingxenye ebalulekile yezindlela zokwemba insimbi zesimanje.

Izindlela zokwemba insimbi ngokuvamile zihlukaniswa izigaba ezimbili: ukwemba phezulu (open-pit) nokwemba ngaphansi komhlaba. Ukwemba phezulu kuyathanda ngenxa yokuthi konga kakhulu futhi kufaneleka ezindaweni ezinkulu, ezingajulile lapho kukhona khona insimbi. Kuhilela ukususa izitshalo namanzi angaphezulu ukuze kudalulwe lapho kukhona khona insimbi. Ukugruba nokuqhuma kuphula insimbi, bese ilayishwa futhi ithuthwa ukuze icutshungulwe.

Imayini engaphansi komhlaba isetshenziswa lapho izinto zensimbi zisezingeni eliphansi ngaphansi komhlaba. Le ndlela ihilela ukwakha imihume ukuze kufinyelelwe imithambo yensimbi. Noma ingabiza kakhulu futhi iyinkimbinkimbi, imayini engaphansi komhlaba inciphisa ukuphazamiseka komhlaba futhi ikhethwa ngezinto ezithile zensimbi ezisezingeni eliphezulu. Ukuqhubeka kwezinto ezisebenza ngokuzenzakalelayo nemishini elawulwa kude kwandise ukuphepha nokusebenza kahle kuzo zombili izinhlobo zemayini.

Amasu amasha afana nokukhipha insimbi ngaphakathi komhlaba (in-situ leaching) kanye nemayini ye-hydraulic ayavela kodwa okwamanje ayivamile ekukhipheni insimbi. Kungakhathaliseki indlela, ukukhetha kuncike ezicini zensimbi, ukujula kwendawo, kanye nezinto zezomnotho. Ukuthuthukisa lezi zindlela kubalulekile ukuze kuhlangatshezwane nesidingo sensimbi ngendlela esimeme.

Ukuqhubeka kobuchwepheshe kudale izinguquko ezinkulu emayini yensimbi ngokuthuthukisa ukunemba, ukukhiqiza, nokuphepha. Ubuchwepheshe obufana nokwenza amamephu nge-GPS, ama-drone, kanye nokubona okukude kuthuthukisa ukunemba kokuhlola. Ukuzenzakalela kanye ne-robotics kuvumela ukusebenza okuqhubekayo kwemishini yokubhoboza, yokuthutha, nokucubungula ngokuphazamiseka okuncane komuntu.

Ngokwesibonelo, amaloli okuthutha azenzakalelayo anciphisa ukusetshenziswa kukaphethiloli kanye nezindleko zabasebenzi ngenkathi kuthuthukiswa ukuphepha kwendawo. Ngaphezu kwalokho, ukuhlaziywa kwedatha yesikhathi sangempela kuvumela ukulungiswa okubikezelayo, kunciphisa isikhathi sokungasebenzi kanye nezindleko zokusebenza. Imishini ethuthukisiwe yokucubungula amaminerali evela ezinkampanini ezifana ne-广州市银鸥选矿科技有限公司 yenza ngcono ukuthuthukiswa kwe-ore, kwandisa isivuno futhi kunciphisa udoti.

Ukuhlanganisa ama-digital twins kanye nezinqumo ezisekelwe ku-AI kuyaqhubeka nokuqhakambisa imisebenzi yokumba. Lezi zibuchwepheshe zisekela ukuphathwa okungcono kwezinsiza, ukuqapha imvelo, kanye nokuthobela imithetho, kuqinisekisa ukuthi imisebenzi yokumba ihlala izinzile futhi iyasebenza.

Indawo yesimanje yokumba umhlaba wensimbi esebenzisa amaloli azishayelayo nemishini yokubhoboza ukuze kuthuthukiswe ukusebenza.

Umhlaba wensimbi iSimandou eseGuinea uyisibonelo sokukhipha umhlaba wensimbi ngobukhulu obukhulu kusetshenziswa izindlela zokumba ezithuthukisiwe. Leli phothulo liqukethe okunye kokugcinwa kwensimbi okucebile emhlabeni. Imisebenzi yokumba lapho isebenzisa izindlela zokumba ezivulekile ihlanganiswe nezitshalo zokucubungula ezisezingeni eliphezulu ukuze kufezekiswe amazinga aphezulu okuthola. Lo msebenzi uhlanganisa izindlela ezizinzile, okubandakanya ukubandakanyeka komphakathi nokuphathwa kwemvelo.

Esinye isibonelo sihlanganisa izimayini zamatshe ensimbi yase-Australia ezisebenzisa ama-crusher aphumelela kakhulu nama-conveyor ahlanganiswe nezinhlelo zokuqapha ezisekelwe ku-AI. Lezi zibonelo zobuchwepheshe zivumela ukuthuthukiswa kwenqubo yonke yokumba ngesikhathi sangempela, kunciphisa ukusetshenziswa kwamandla futhi kwandise ukukhiqiza. Ukuphumelela okunjalo kubonisa ukuthi ukwamukela ubuchwepheshe kuguqulela kanjani ezuzweni zezomnotho nezemvelo.

Emhlabeni wonke, ukuhlanganisa ama-spiral concentrator amasha nemishini yokuhlukanisa i-gravity kuthuthukisa ukuthuthukiswa kwamatshe ensimbi. Lezi zindlela, ezinikezwa abaholi bemboni njenge-广州市银鸥选矿科技有限公司, zinikeza amazinga aphezulu okuphinde kutholwe izinhlayiya ezincane, zithuthukisa ikhwalithi yamatshe enikezwa abakhiqizi bensimbi.

Ukuphumelela kwezindawo zokumba umhlaba wensimbi kuhlanganisa izindlela eziningana zamasu. Okokuqala, ukumodela okuphelele kwezinsiza nokuhlelwa komgodi kuqinisekisa ukuthi ukukhiqiza kunenzuzo kwezomnotho futhi kunempilo kwezemvelo. Ukusebenzisa idatha enembayo yezinto eziphilayo kusiza ukunciphisa ukuchitha nokukhomba izindawo ezinensimbi esezingeni eliphezulu. Okwesibili, ukutshala imali ezintweni zokusebenza ezithuthukisiwe nokuzenzakalela kunciphisa izindleko zokusebenza futhi kuthuthukisa ukuphepha.

Okwesithathu, ukuqeqeshwa okuqhubekayo nokuthuthukiswa kwabasebenzi kunika amandla abasebenzi ukuthi basebenzise ubuchwepheshe obusha ngempumelelo. Okwesine, ukusebenzisa izinhlelo zokuphatha imvelo kunciphisa umthelela wezimayini emvelweni futhi kuhambisana nemithetho, okusekela ukuqhubeka kokusebenza kwesikhathi eside. Ekugcineni, ukubambisana nabahlinzeki bezobuchwepheshe kanye nochwepheshe bokucubungula amaminerali, njenge-广州市银鸥选矿科技有限公司, kusiza ukwamukela izindlela ezingcono kakhulu nezixazululo ezintsha ezenzelwe izindawo ezithile zezimayini.

Izinsiza zangaphakathi njenge-Amacala ikhasi linikeza ukuqonda okwengeziwe kubuchwepheshe bokucubungula amaminerali kanye nempumelelo yamaphrojekthi, okungaqondisa ukuthuthukiswa emisebenzini yakho.

Ikakhwezi lemigodi yensimbi itholakala ezindleleni ezizinzile, eziholwa ubuchwepheshe ezilinganisa ukukhiqiza nokunakekelwa kwemvelo. Njengoba isidingo sensimbi siqhubeka, imisebenzi yemigodi kufanele iguquke ngokwamukela izindlela ezintsha, amathuluzi edijithali, nezindlela zokucubungula ezisebenzayo. Izinkampani ezihlanganisa ubuchwepheshe obusezingeni eliphezulu futhi ezibambisana nabachwepheshe bemboni, okubandakanya ochwepheshe abafana ne-广州市银鸥选矿科技有限公司, zizoholela ushintsho oluya emayini ehlakaniphile, eluhlaza.

Ukuqhubeka kocwaningo nentuthuko, kuhlangene nezinqubomgomo zemigodi eziphethe, kuzoqinisekisa ukuthi insimbi ihlala iyimithombo ethembekile emashumini eminyaka azayo. Ukwamukela lezi zintuthuko akugcini nje ngokwenza kahle ukukhipha imithombo kodwa futhi kusekela intuthuko yomphakathi nokulondolozwa kwezemvelo, kuqinisekisa ikhakhwezi eliphumelelayo emkhakheni wezimayini zensimbi.

Ngeminye imininingwane eningiliziwe ngemishini yokucubungula amaminerali, vakashela i-Ikhayakanye ne-Imikhiqizo amakhasi.
