Ukwakhiwa kwemibhobho yindlela yokwakhiwa kwemibhobho ephantsi komhlaba ephuhliswe emva kolwakhiwo lwekhaka. Ayifuni ukugrunjwa kweeleya zomphezulu, kwaye inokudlula kwiindlela, oololiwe, imilambo, izakhiwo ezingaphezulu, izakhiwo ezingaphantsi komhlaba, kunye nemibhobho eyahlukeneyo engaphantsi komhlaba.

Ukwakhiwa kombhobho kusebenzisa i-thrust ye-cylinder yokukrazula kunye negumbi lokudlulisa phakathi kwemibhobho ukutyhala umbhobho wesixhobo okanye i-road-header ukusuka ekusebenzeni kakuhle kumaleko womhlaba ukuya kwindawo eyamkelekileyo. Ngexesha elifanayo, umbhobho ngokukhawuleza emva kokuba umbhobho wesixhobo okanye umatshini wokubhobhoza ungcwatywe phakathi kwamaqula amabini, ukuze kuqatshelwe indlela yokwakha yokubeka imibhobho engaphantsi komhlaba ngaphandle kokumba.
