Amazinyo okumba ajikelezayo ayingxenye ebalulekile ezinhlobonhlobo zemishini yokumba umhlaba kanye neyezimayini:
I-Trenching & Ukumba: Ifakwe kumasondo e-trencher kanye namakhanda okugaya afakwe kuma-excavator okumba imisele yezinsiza enhlabathini nasedwaleni.
I-Surface Mining: Isetshenziswa kubavukuzi abaqhubekayo bangaphezulu ukuze kumbiwe ungqimba ngalunye lwamalahle namanye amaminerali.
I-Rock Wheel Excavators: Kufakwe emakhanda ajikelezayo "amasondo edwala" noma "abasiki bedwala" ukuze kumbiwe amatshe aqinile emhubheni, ekumbeni, nasekuthuthukisweni kwesayithi.
Ukubuyiswa Nokwehliswa Komhlaba: Kusetshenziswa kumakhanda okusika ama-dredgers ukusika nokuxuba izinto ezisetshenziswa ngaphansi kwamanzi.
Ithebula elilandelayo lifingqa izici eziyinhloko ukuze uthole ukubuka konke okusheshayo:
| Isici | Incazelo | Inzuzo |
| Umsebenzi Oyinhloko | Ukusika, ukuphula, nokuhlephula impahla ephansi ngesenzo sokuzungeza. | Inika amandla ukumba okusebenzayo. |
| Okubalulekile | Ithiphu ye-tungsten carbide iboshwe emzimbeni wensimbi onamandla aphezulu. | Ihlanganisa ukumelana nokugqoka okwedlulele nokuqina komthelela omkhulu. |
| I-Core Mechanism | Umthelela kanye namandla okugunda kusuka esigubhu esijikelezayo; ngokuvamile kuhlanganisa ukuzishintshanisa. | Iphromotha ngisho nokugqoka, ukuzilola, nempilo ende yesevisi. |
| Inzuzo Eyinhloko | Ukusebenza Okuphakeme Kokumba kanye Nesikhathi Esincishisiwe Sokuphumula. | Igcina ukusebenza kokusika ezimeni zokugwaza, inciphisa imvamisa yokushintsha. |
| Izisetshenziswa | Ama-trenchers, abavukuzi abaqhubekayo, amasondo e-rock, abasiki be-dredger. | Ithuluzi lokusika elibalulekile lemishini yokumba yesitayela se-rotary. |
Kafushane, I-Rotary Digging Amazinyo zingamathuluzi ayisisekelo, asebenzisekayo avumela ukumba kwemishini yesimanje. Idizayini yazo eqinile nehlakaniphile ivumela imishini esindayo ukuthi imbe ngokuphumelelayo nangokwezomnotho kwezinye zezinto eziqinile emhlabeni, kusukela enhlabathini ehlangene kuya edwaleni eliqinile.
