Ukusebenza kwemigodi yamalahle ngaphansi komhlaba, izimo zokusebenza ziyinkimbinkimbi futhi zinzima, indawo inzima, umthwalo uyashintsha ngokushintsha kwezimo zejoloji, ububanzi bokusebenza bulinganiselwe kakhulu, kukhona ukushayisana, ukushayisana nokuwa kanye nezinye izingozi, kukhona amanzi, uwoyela, i-emulsion kanye neminye imiphumela enjinini, futhi kukhona igesi, ingozi yokuqhuma kothuli lwamalahle, ukudlidliza kokusebenza kwemishini kanye nezinye izimo ezimbi. Indlela yokuqinisekisa ukuthi imoto ayinazo izingozi ekusebenzeni ibaluleke kakhulu ekukhetheni kahle imoto. Ngakho-ke, ukukhetha imoto kumele kucabangele ngokugcwele indawo yokusebenza kanye nezimo ezingenhla, ukuze imoto ngokwayo ifanele izidingo zendawo yokusebenza kanye nezimo ngokwesakhiwo nokusebenza. Ngakho-ke, izimiso ezilandelayo kufanele zicatshangelwe lapho ukhetha imoto:
1 Imoto engaqhumi kufanele ikhethwe ngokwezici zokusebenza kwemishini yokudlulisa kanye nezimo zemvelo, amandla afanayo, i-voltage, isivinini, i-torque yokuqala kanye nomthamo wokulayisha ngokweqile. Ngenxa yokuthi umthungo wamalahle osikiwe ngumgundi ngezinye izikhathi ugcwala i-gangue, futhi umthungo wamalahle uqinile futhi uthambile, isenzakalo sokulayisha ngokweqile sivame ukwenzeka lapho imoto isebenza. Ama-conveyor omgwaqo, ikakhulukazi ama-conveyor okujikeleza ubuso, avame ukuqala ngokulayisha ngokweqile, futhi ngokuzumayo aqongelele amalahle noma aguqe abe amalahle ngesikhathi sokusebenza, ngakho-ke isenzakalo sokulayisha ngokweqile sivame ukwenzeka. Ngakho-ke, imoto engaqhumi ene-torque ephezulu yokuqala kufanele ikhethwe.
2 Injini engaqhumi kumele ibe yiyunithi yokuhlola eyaziwayo ezweni lonke ukuze iphumelele ukuhlolwa, futhi ithole isitifiketi esingaqhumi kanye nelayisensi yokukhiqiza umkhiqizo, futhi iHhovisi lokuphepha kwamalahle le-National Coal mine Administration likhiphe isitifiketi somgodi ongaphansi.
3 Ngokwezimiso zokusebenza okuphephile, ukulungiswa okulula, ubuchwepheshe obuthuthukisiwe, ukuhlaziywa okubanzi kwezomnotho nokunengqondo, ukukhetha kwesayensi.
