Ukuqhuma kwesibhamu, okwaziwa nangokuthi ukuqhunyiswa kwesihlabathi, ukupholisha, ukususwa kokugqwala, ukuhlanzwa, njll., ubuchwepheshe obujwayelekile bokwelapha obusebenzisa insimbi ekhishwa ngesivinini esiphezulu noma izinhlayiya ezingezona ezensimbi ukuze kuthinte indawo engaphezulu yento ukuze kuzuzwe ukugqwala, ukususwa kokungcola, ukwanda. ukuhwaqazeka kwendawo, ukuthuthukisa ikhwalithi yendawo, neminye imiphumela. Indlela yokucubungula ngomshini.
Ukuqhunyiswa kwesibhamu kusetshenziselwa ikakhulukazi ukwelapha phezulu nokuhlanza izinto zensimbi nezingezona ezensimbi, njengezimoto, izimoto zikaloliwe, okomshini, amabhuloho, izakhiwo, amapayipi, ukulingisa nezinye izinkambu. Ayikwazi ukususa kuphela ukungcola okufana nokugqwala, ungqimba lwe-oxide, upende, usimende, uthuli, njll., kodwa futhi yandise ubulukhuni bezinto ezibonakalayo, ithuthukise ikhwalithi yendawo, ithuthukise ukunamathela kokunamathela, futhi yandise impilo yesevisi yezinto.
Ukuqhuma kwesibhamu kuhlukaniswe ikakhulukazi izinhlobo ezimbili: ukuqhuma kwesibhamu somoya ocindezelwe kanye nokuqhuma kwesibhamu. Ukudubula komoya ocindezelwe kusebenzisa umoya ocindezelwe ukuze kukhiqizwe ukugeleza kwejethi ngesivinini esikhulu ukufafaza izinhlayiya ebusweni bento ukuze kuqedelwe ukuhlanza, ukususa ukungcola okungaphezulu, ungqimba lwe-oxide, ukunamathela, njll.; ukuqhuma kokudubula komshini kuwukukhipha izinhlayiya phezu kwento ngesondo eliqhunyiswa ngomshini ukuze kuqedelwe ukuhlanzwa kwendawo, kwandise ukuhwaqana kwendawo, kanye nokwenza ngcono ukunamathela kokunamathela.
