1. Ukusebenza okuthembekile kwe-conveyor yebhande. Ezingxenyeni eziningi zokukhiqiza ezibalulekile, njengokuthuthwa kwamalahle ezimbonini zamandla kagesi, ukuthuthwa kwezinto ezixegayo ezitshalweni zensimbi nasezitshalweni zikasimende, noma ukulayishwa nokwehliswa kwemikhumbi emachwebeni, kuzosetshenziswa isithuthi sebhande. Ngoba kulezi zikhathi, uma sekumisiwe, kuzobangelwa ukulahlekelwa okukhulu, futhi umthumeli webhande angakwazi ukubona ukuthutha okuqhubekayo, ngakho-ke isetshenziswa kabanzi.

I-2, ukusetshenziswa kwamandla okuphansi kwe-conveyor yebhande. Njengoba cishe akukho ukunyakaza okuhlobene phakathi kwezinto ezibonakalayo kanye nebhande lokuhambisa, hhayi nje ukumelana nokugijima kuncane, kodwa futhi ukugqoka nokuphuka kwempahla kuncane, futhi ukukhiqiza kuphezulu. Konke lokhu kuyasiza ekwehliseni izindleko zokukhiqiza.

I-3, ukuguquguquka komugqa wokudlulisa webhande lokuhambisa kanye nokuvumelana nezimo. Ubude bomugqa buncike esidingweni. Okufushane ngamamitha ambalwa, ubude bungafinyelela ngaphezu kwe-10km. Ingafakwa emhubheni omncane noma phezu kwendawo lapho ithrafikhi inzima noma iyingozi.

4, ezokuthutha ibhande conveyor nezimo. Isidlulisi sebhande singathola okubalulekile ukusuka endaweni eyodwa noma ngaphezulu. Ingaphinde ikhishwe kumaphuzu amaningi noma izigaba eziningana. Lapho ngasikhathi sinye emaphuzwini amaningana ukuya ekudleni kwebhande lokudlulisa noma ubude bomthumeli webhande eduze kwanoma yiliphi iphuzu ngokusebenzisa imishini yokuphakela umfaniswano ukuthutha ukuletha impahla, umthumeli webhande uba isiqu esikhulu sokuthutha.
