Amasondo angaphansi komhlaba ayizinhlobo ezikhethekile zamasondo eziklanyelwe ukusetshenziswa ezimayini ezingaphansi komhlaba kanye nemisebenzi yomhubhe. Lamasondo enzelwe ukumelana nezimo ezinzima neziyinselele ezitholakala ezindaweni ezingaphansi komhlaba, okuhlanganisa izindawo ezimahhadlahhadla, izinto ezilimazayo, nezindawo ezivalekile. Kunezinhlobo ezahlukene zamasondo angaphansi komhlaba, ngalinye lisebenzela izinjongo ezithize emsebenzini wezimayini nomhubhe. Ezinye izibonelo ezijwayelekile zihlanganisa: 1. **Amasondo Eloli Lezimayini**: Amaloli ezimayini angaphansi komhlaba izimoto ezithwala kanzima ezisetshenziselwa ukuthutha impahla kanye namaminerali ezimayini ezingaphansi komhlaba. Amasondo alawa maloli aklanyelwe ukuthwala imithwalo esindayo, anikeze ukudonsa ezindaweni ezingalingani, futhi amelane nokuguga nokudabuka kwezinto ezihugayo. 2. **Amasondo Enqola Yamayini**: Izinqola zemayini amakalishi amancane, anamasondo asetshenziselwa ukuthutha izinto ngaphakathi kwemigudu yezimayini. Amasondo akulezi nqola aqinile futhi aqinile, awenza akwazi ukuhamba ezindleleni eziwumngcingo nezingalingani. 3. **Amasondo Omshini Wokubhokisa Umhubhe (TBM)**: Imishini ebhokisayo yomhubhe iyimishini emikhulu esetshenziselwa ukumba imigudu emisebenzini yezimayini neyokwakha. Amasondo ale mishini aklanywe ngokukhethekile ukubamba amandla amakhulu ahilelekile ekudwebeni umhubhe futhi amelane nemvelo egwazayo yedwala nenhlabathi ehlangana nayo. 4. **Amasondo Ebhande Le-Conveyor**: Emisebenzini yezimayini engaphansi komhlaba, amabhande okuthutha asetshenziselwa ukuthutha izinto ezihamba amabanga amade. Amasondo kumasistimu okuthutha aklanyelwe ukusekela imithwalo esindayo futhi anikeze ukunyakaza okushelelayo kumathrekhi okuthutha. 5. **Amasondo Esitimela**: Izitimela ezingaphansi komhlaba zisetshenziselwa ukuthutha abasebenzi kanye nezinto zokwakha ngaphakathi kwemayini. Amasondo akulezi zitimela aklanyelwe ukusebenza emizileni eyigeji emincane ezindaweni ezivalekile. Amasondo angaphansi komhlaba ngokuvamile enziwa ngezinto eziqinile, njengensimbi noma ingxubevange, ukuze amelane nezimo ezinzima ngaphansi komhlaba. Angase futhi ahlonyiswe ngezici ezengeziwe ezifana nokunyathela okuqinisiwe, ama-coating akhethekile, noma ukwelashwa kokushisa ukuze kuthuthukiswe ukuqina nokusebenza kwazo. Uma kubhekwa indawo eyinselele kanye nokucatshangelwa kokuphepha ezimayini ezingaphansi komhlaba kanye nomhubhe, ukuklanywa nokwakhiwa kwamasondo angaphansi komhlaba kubalulekile ukuze kuqinisekiswe ukusebenza kahle nokuphephile kulezi zimboni.
