Summary: Izinsiza zomhlaba zinzindawo eziyisisekelo zokuba khona nokuthuthukiswa komuntu. Ngisho nasemasosheni wanamuhla, izinsiza zomhlaba zisashintsha indima ebaluleke kakhulu empilweni yansuku zonke yabantu...

Izinsiza zamaminerali yizisekelo zemvelo zokuba khona nokuthuthuka komuntu. Ngisho nasemphakathini wesimanje, izinsiza zamaminerali zisahamba phambili ngokungashintshi ekuphileni kwansuku zonke kwabantu. Inqubo yokuchoboza nokomilela iyisigaba esibalulekile enqubweni yamaminerali, esiphinde sidinga utshalomali olukhulu nokusetshenziswa kwamandla okukhulu. Ngakho-ke indlela yokuthuthukisa ukusebenza kwemishini yokuchoboza nokomilela kuthinta kakhulu. Kulesi sihloko, ikakhulukazi sikhuluma ngezinto ezithuthukisiwe enqubweni yokuchoboza nokomilela yamaminerali.

Ukuguqulwa nokuqeshwa kwezimboni

Inqubo yokugaya ikakhulu isetshenziswa ekukhululweni kwezinsika zomhlaba futhi yenza usayizi wezicubu uhlangabezane nezimfuneko zokugcina. Inqubo yokugaya isici somhlaba ithatha amandla amaningi kodwa inezehlakalo ephansi. Ukusetshenziswa kwamandla ohlelo lokucindezela kuyathatha cishe u-8% kuya ku-12% wokusetshenziswa kwamandla kohlelo lokugaya. Ngakho, ukuthuthukisa inqubo yokugaya kuyindlela ephumelelayo ukufinyelela ukusebenza kahle okuphezulu nokusetshenziswa kwamandla okuphansi nokukwenza kube nenzuzo yezomnotho.

Ukucisha Okuningi, Ukukhukulisa Okuncane

Ukucindezela kwemaminerali kuvame ukufeza ngokuchofoza noma ngamandla okushaya kumaminerali, kuyilapho inqubo yokugaya ivame ukufeza ngokushaya, ukugaya kanye nokuhlakaza, ngakho-ke isilinganiso sokusetshenziswa kwemandla enqubweni yokucindezela sibhakabhaka kakhulu kunaleso sencazelo yokugaya. Singathatha inqubo yokucindezela neyokugaya njengehlandla lonke. Ngemuva kokunquma usayizi wemkhiqizo wokugcina, singamukela isu lokunciphisa ukucindezela nokugaya okuncane ukuze sifinyelele kuzuziso zezomnotho ezihamba phambili.

Ngokuvamile, kunamaqhinga amabili:

  • Thatha ukuthengwa kwemishini yokuphuka ethuthukisiwe kakhulu.
  • 2. Thuthukisa inqujwayelo yokucwilisa. Kufanele sikhethe inqujwayelo yokucwilisa efanele ngokuvumelana nobukhulu bemisebenzi yokuthuthukiswa, izici zeminerali, ubukhulu bokudliwa, ubukhulu bemikhiqizo yokugcina, kanye nezinye izici.

Qeqesha Ukuqhuma Okwengeziwe

Ukuqhuma okwengeziwe kokuthuthukiswa kungabatshekisa iminerali ye-gangue ngesikhathi, okuyinto engenza kungabi nzima umsebenzi wokuthuthukiswa, futhi kunciphisa izindleko zokufakelwa kwemisebenzi yokuthuthukiswa.

Ukudumisa Izinto Zokucisha Ngokucisha Ngokulula

Njengoba ukusebenza kahle kwesinqumo sokucisha emisebeni yokuthuthukisa kuyancane kakhulu, futhi cishe amaphesenti angu-85 wemvelo yonke isebenzisa esigabeni sokucisha, ngakho-ke singasebenzisa izinto zokucisha ngobuchwepheshe ukuze sihlukanise inqujwayelekile yokucisha ukuze kunciphisa ukusetshenziswa kwamandla.

Ukuguqulwa Kwenqubo Yeminyaka

Kwezinye izitshalo zokuhlanzwa zasendulo ezinamandla amakhulu okukhanga, izinga lokukhiqiza langempela lilinganiselwa cishe half yesilinganiso esihleliwe ngenxa yezizathu ezihlukahlukene. Futhi ngokucwiliswa kwezinsiza zomzali, inzuzo yazo yezomnotho iyancipha. Ngakho indlela efanele yokuxazulula le nkinga ukubuyekeza inqubo ukuze kuzuze ukonga amandla. Futhi okubalulekile, kuqinisekiswe usayizi womkhiqizo wokugcina.
