1. Umthamo womkhiqizo akufanele udlule u-25% wevolumu yebhokisi lemishini, futhi isisekelo sesampula akufanele sidlule u-50% wendawo evundlile yendawo yokusebenza.

2. Uma usayizi wesampula ungahambisani nesigaba sangaphambilini, imininingwane efanele kufanele ichaze ukusetshenziswa kwezindlela ezilandelayo:

① Igumbi lokuhlola isihlabathi nothuli lihlola izingxenye ezimele umkhiqizo, okuhlanganisa izingxenye ezifana neminyango, iminyango yokungenisa umoya, izisekelo, imiphini yokuvala, njll.
② Hlola amasampula amancane anemininingwane yomklamo efanayo nomkhiqizo wokuqala.
③ Hlola ingxenye yokuvala yomkhiqizo ngokwehlukana;

Izingxenye ezincane zomkhiqizo, njengeziphetho namakhoyili okuqoqa, kufanele zigcinwe endaweni yazo ngesikhathi senqubo yokuhlola;

Iigumbi lokuhlola isihlabathi nothulikusekelwe ezimweni zokusebenza komkhiqizo. Ibhokisi lomkhiqizo lingahlukaniswa ngezinhlobo ezimbili:

1: Ingcindezi engaphakathi kwebhokisi lomkhiqizo ingahluka kwengcindezi yangaphandle yomkhathi, isibonelo, ngenxa yomehluko wengcindezi yomoya ebangelwa imijikelezo yokushisa ngesikhathi sokusebenza.
Kumasampula ane-casing yohlobo 1, wafake ngaphakathi kwebhokisi lemishini bese uwafaka endaweni yawo evamile yokusetshenziswa. Ibhokisi lokuhlola isihlabathi nothuli lixhunywe kuphampu ye-vacuum ukuqinisekisa ukuthi ingcindezi yangaphakathi yesampula iphansi kunengcindezi yomoya. Ngale njongo, kufanele kuhlinzekwe imigodi efanele e-casing. Uma sekukhona imigodi yokukhipha amanzi odongeni lwesampula, ithubhu ye-vacuum kufanele ixhunywe kulowo mgodi ngaphandle kwesidingo sokubhoboza kabusha.

Uma kunemigodi yokukhipha amanzi engaphezu kweyodwa, ithubhu le-vacuum kufanele lixhunywe kwenye yemigodi, kanti eminye imigodi kufanele ivalwe ngesikhathi sokuhlolwa.

2: Umfutho womoya ngaphakathi kwebhokisi lesampula ufana nomfutho wangaphandle. Kumasampula anamagobolondo ohlobo 2, wabeke ekamelweni lokuhlola bese uwafaka endaweni yawo evamile yokusetshenziswa. Zonke izimbobo ezivulekile zihlala zivulekile. Izidingo nezixazululo zokubekwa kwezingcezu zokuhlola ebhokisini lemishini.
Lokhu okungenhla konke okuqukethwe kokubekwa kanye nezidingo ze-ibhokisi lokuhlola isihlabathi nothuliyemikhiqizo yokuhlola.
