Ngokuthuthuka kwamazinga okuphila kanye nokuthuthuka okusheshayo kwezimboni, isidingo sezinsiza ezibonakalayo siyakhula.Namuhla, amazwe athuthukile nasathuthuka abheka ukusebenza kwezinsiza kanye nokuthuthukiswa kwezinsiza njengezinyathelo zamasu.Ukukhishwa kwezinto ezibonakalayo kuphinde kwaholela ekuthuthukisweni kobuchwepheshe bezimayini, ubuchwepheshe bezimayini usuku nosuku, kube nenani elikhulu lobuchwepheshe nezindlela zezimayini ezisebenza kahle, eziphephile, nezingabizi kakhulu.
Ubuchwepheshe bezimayini e-United States yibo obuthuthuke kakhulu, futhi imishini yayo yokumba umgodi ovulekile inezici ezimbili ezigqame kakhulu: Okokuqala, imishini yezimayini emikhulu, okwesibili, i-automation yemishini kanye nobuhlakani.Kusukela ngeminyaka yawo-1990s, ukuqapha ngesikhathi sangempela kwekhompuyutha yebhodi elilodwa lemishini emikhulu yomgodi ovulekile e-United States isetshenziswe kabanzi.

Imishini yayo yokumba ngaphansi komhlaba inalezi zimpawu ezilandelayo:
1)Izisetshenziswa zikaJackie Chan ezisekela izinga eliphezulu lemishini.Imishini yangaphandle ethuthukisiwe yezimayini engaphansi komhlaba isuka ekumbiweni kwamadwala iye ekuthunyelweni, yonke imisebenzi esekela umgodi wokudiliza, zonke izinqubo ngaphandle kokusebenza ngezandla, akukho msebenzi wezandla osindayo.Izinhlobo ezahlukene ze-hydraulic drilling rig, i-hydraulic rock drill, idizili noma i-electric kanye ne-remote control scraper iyimishini eyisisekelo evamile.Ukuze uzijwayeze nezindawo zikaJackie Chan ezisetshenziswa ngomshini, izinto zokusebenza ezinkulu, i-miniaturization, i-serialization, i-standardization, izinga eliphezulu lokujwayelekile.
2) Imishini engenawo ithrekhi, i-hydraulic, izinga eliphakeme lokuzenzakalelayo.Imishini yezimayini ethuthukisiwe yangaphandle ibonakale ngokugcwele i-trackless, hydraulic.Ku-automation, sethule ngempumelelo ubuchwepheshe obusha obufana namarobhothi angashayeli namarobhothi.
I-3) Imishini nokusebenza kobuchwepheshe kuvuthiwe, ukwethembeka okuphezulu.Njengamanje, imayini ejule kakhulu emhlabeni isentshonalanga yeGoli, eNingizimu Afrika.Phakathi kwayo, imithombo engu-No.3 kanye ne-No.3 idlula amamitha angu-3500, okuyindawo ejulile abantu abangafinyelela kuyo.Imayini ejule kakhulu e-United States, eseMayini Yegolide yaseHomestok eNingizimu Dakota, iyimayini endala futhi egqitshwe kakhulu eNyakatho Melika.Inomlando weminyaka eyi-130 kanye nokujula okungamamitha ayi-2,500.

Mayelana Nobuchwepheshe Bezimayini:
1.Leaching technology
Njengamanje ekubuyiseni ithusi lezinga eliphansi, insimbi yegolide, i-uranium ore isetshenziswe kabanzi kubuchwepheshe be-leaching, i-leaching in situ leaching, i-heap leaching kanye ne-in situ crushing leaching izigaba ezintathu.I-United States, i-Canada, i-Australia namanye amazwe abhekana ne-0.15% -0.45% yensimbi yethusi esezingeni eliphansi, i-copper oxide ore engaphezu kuka-2% kanye ne-0.02% -0.1% ye-uranium ore ngokuyisisekelo ayinqwaba yokucwiliswa kanye ne-situ blasting leaching recovery.

2.Ubuchwepheshe bezimayini ezijulile
Ngenxa yokwanda kwezinsiza zezimayini, izinsiza ziyancipha kanti nobuchwepheshe obungashoni kakhulu bezimayini ezijulile sebuchichima kakhulu.Ukusekelwa kwezobuchwepheshe kwezimayini ezijulile kuphezulu.Njengoba ukujula kujula, ubunzima okuhlangatshezwane nabo buyanda, Ukwanda, izinkinga zokudonsa amanzi kanye nokukhipha umoya, ukukhuphuka kwezinga lokushisa kwamadwala.Namuhla, ukujula kwezimayini ezimayini okungewona amalahle ezweni lakithi ngokuvamile akudluli ku-700-800m, kodwa eminyakeni yamuva nje amanye amadiphozithi anokujula okungaba ngu-1000m athuthukisiwe.

3.Imayini engaphansi komhlaba ehlakaniphile
Ukuthuthukiswa kwesayensi nobuchwepheshe, isivinini sokwenziwa sisalele emuva kakhulu emshinini okhaliphile, ngenxa yokusetshenziswa kwamadivaysi ahlakaniphile, okwenza ukusebenza kahle kwezimayini kukhule kakhulu, kunciphisa ingozi yokuphepha engaba khona.Ngenxa yokutshalwa kwezimali ohlelweni oluhlakaniphile lokumbiwa kwensimbi, uhlelo lokuphatha izimayini kanye nokuqashwa kwabasebenzi kufanele kuqedwe.Izinhlelo zezimayini ezizenzakalelayo nezihlakaniphe kakhulu ziyisihluthulelo sokuqinisekisa ukumbiwa kwezimayini okuphephile nokusebenza kahle.

I-4.Ukugcwalisa ubuchwepheshe bezimayini busetshenziswa kakhulu
Ngokusho kwezimo ezahlukene, usebenzisa izinto zokugcwalisa ezahlukene.Ubuchwepheshe bokugcwalisa obusetshenziswa emhlabeni wonke: ukugcwaliswa kwesihlabathi samanzi, ukugcwaliswa okomile, ukugcwaliswa okuqinile kwamanzi, ukugcwalisa usimende.Ukugcwaliswa kwe-cementing kuhlukaniswe: i-sub-paragraph tailings yokugcwalisa i-hydraulic, ukugcwalisa okunye ukugcwaliswa kwe-hydraulic (i-concentration ephezulu yokulethwa kwe-self-slip), i-all-tailing paste self-slip paste filling kanye ne-tailing paste pump.Njengamanje, isincomo samazwe ngamazwe ukugcwaliswa kwephampu ye-tailings egcwele.Ubuchwepheshe obusha bokugcwalisa buzokwazi ukuhlangabezana kangcono nezidingo zokuvikela izinsiza, ukuvikela imvelo, ukuthuthukisa ukusebenza kahle kanye nokuqinisekisa ukuthuthukiswa kwezimayini.Ukugcwalisa imboni yezimayini ekhulwini lama-21 kuzoba nethemba elibanzi lentuthuko.
