Ukukhishwa kwesihlabathi esiluhlaza asikho isidingo sokumisa futhi kuthatha i-bentonite njengesibopho. Isici esiyisisekelo sesihlabathi esiluhlaza ukuthi akudingeki ukuba somiswe futhi siqiniswe, kuyilapho sinamandla athile amanzi. Nakuba amandla ephansi, inokubuyela emuva kangcono futhi kulula ukuyinyakazisa; ngaphezu kwalokho, iinqubo yokuphonsa isihlabathi esiluhlazainezinzuzo eziningana zokusebenza kahle kokubumba, umjikelezo omfushane wokukhiqiza, izindleko eziphansi zezinto ezibonakalayo futhi kulula ukuhlela ukukhiqizwa kokugeleza. Kodwa-ke, ngenxa yokuthi isikhunta sesihlabathi asomisiwe, ukuhwamuka komswakama kanye nokufuduka kubonakala ebusweni besikhunta sesihlabathi ngesikhathi sokubunjwa, okwenza ukubunjwa kuthambekele ekubeni nama-blowholes, ukufakwa kwesihlabathi, isihlabathi esiqhumayo, isihlabathi esinamathelayo nokunye ukukhubazeka kokuphonsa.
Ukuze unikeze ukudlala okugcwele izinzuzo zokubumba kwesihlabathi esiluhlaza futhi kuthuthukisweizinga lokulingisa, kuyadingeka ukugcina ukusebenza kwesihlabathi sokubumba okuzinzile, ukubunjwa kwesihlabathi okuhlangene nokufana okufanayo kanye nenqubo yokuphonsa enengqondo phakathi nenqubo yokukhiqiza. Ngakho-ke, ukuthuthukiswa kobuchwepheshe bokubumba isihlabathi esiluhlaza bekulokhu kuhlotshaniswa eduze nokuthuthukiswa komshini wokubumba kanye nobuchwepheshe bokubumba.
Muva nje, ukubumba okwenziwe ngomshini kwesihlabathi esiluhlaza sekuthuthukile kusukela ekubumbeni umshini okuvamile kuya ekubumbeni komshini ominyana kakhulu. Ukukhiqiza kokubumba, ukubumbana kwezibumbe zesihlabathi, kanye nokunemba kobukhulu bokubunjwa kuyaqhubeka nokwanda, kuyilapho inani elibushelelezi lokubunjwa liqhubeka nokuncipha.Inqubo yokubunjwa kwesihlabathi esiluhlaza (uma upende ungafakwanga) ingaphinda ikhiqize insimbi enesisindo esingamakhilogremu angamakhulu amaningana.
Isihlabathi esiluhlaza ngokuvamile sakhiwe isihlabathi esisha, isihlabathi esidala, i-bentonite, i-adenda kanye nenani elifanele lamanzi. Ngaphambi kokwenza isilinganiso sesihlabathi sokubumba, kuyadingeka ukunquma ububanzi bokusebenza nokulawula inani eliqondiwe lesihlabathi sokubumba ngokusho kohlobo lwe-alloy ethululiwe, izici nezidingo zokubunjwa, indlela yokubumba kanye nenqubo kanye nendlela yokuhlanza. . Ngemuva kwalokho, ngokusho kwezinhlobonhlobo kanye nokucaciswa kwezinto ezihlukahlukene zokusetshenziswa, indlela yokucubungula isihlabathi, imishini, isilinganiso sesihlabathi kuya kwensimbi kanye nesilinganiso sokulahlekelwa okuvuthayo kwezinto ezihlukahlukene zisetshenziselwa ukwakha isilinganiso sesihlabathi. Izinkomba zobuchwepheshe kanye nezilinganiso zesihlabathi sokubumba zinganqunywa kuphela ngemva kokuqinisekisa ukukhiqizwa kwesikhathi eside.
