Isando esingaphansi komgodi siyisisetshenziswa esiyisisekelo esidingekayo kumaphrojekthi okumba. Isando esidonsela phansi siyingxenye ebalulekile yomshini wokumba imbobo ephansi kanye nethuluzi elisebenzayo lensimbi yokumba imbobo ephansi. Isetshenziswa kakhulu ezimayini, amalahle, ukongiwa kwamanzi, imigwaqo emikhulu, izitimela, ezokwakha kanye neminye imisebenzi yobunjiniyela.
Umgomo wayo wokusebenza uthi: umoya ocindezelwe ungena kwisando se-DTH ngepayipi lokubhoboza, bese ukhishwa ku-drill bit. I-exhaust gas isetshenziselwa ukususa i-slag. Ukunyakaza okujikelezayo kwe-breaker kunikezwa ikhanda elijikelezayo, futhi i-shaft thrust inikezwa yi-propeller futhi idluliselwe ku-breaker ngokusebenzisa ipayipi yokubhoboza. I-adaptha isetshenziswa kakhulu ukudlulisa ukunyakaza nokujikeleza kubhithi lokubhoboza. Indandatho ye-snap ilawula ukunyakaza kwe-axial ye-drill bit, futhi i-valve yokuhlola isetshenziselwa ukuvimbela i-rock slag nezinye izinsalela ekungeneni kwesando lapho ukunikezwa komoya ocindezelwe kumisiwe. Phakathi nenqubo yokumba, i-drill bit iphushwa esando futhi icindezelwe ngokumelene ne-adaptha. Ngalesi sikhathi, i-piston ithinta ngokuqondile i-drill bit ukubhola idwala. Njengoba i-drill bit isuka phansi embobeni, iqala ukuvunguza ngamandla. Lokhu kuvumela izinto ukuthi ziqoqwe endaweni eyodwa.
Ngokuvamile, amamodeli wesando ahlukaniswa kakhulu ngokwesisindo sawo, ukujula kokubhola, ububanzi bebhithi yokubhoboza, umthamo wokucubungula umshini wokumba, amandla omshini wokumba, njll. ukujula nobubanzi bokubhoboza kuzoba kukhulu.
Kunezici eziningi okufanele uzicabangele lapho ukhetha i-drill rig. Awukwazi ukukhetha lolu hlobo lwe-drilling rig ngenxa nje yomthamo walo omkhulu wokucubungula. Ukukhetha i-rig yokumba efanelekile kudinga ukusekelwe ezintweni okufanele ziphulwe, umthamo wokucubungula ngesikhathi somsebenzi, namandla omshini wokumba.
Amamodeli ahlukene wemishini yokumba azoba namanani ahlukene. Kubandakanya izici ezifana nezinto ezihlukene ezisetshenziswa emshinini wokumba, okuqukethwe kwezobuchwepheshe kwe-rig yokumba, amandla okucubungula we-drilling rig, njll., okuthinta intengo ye-rig yokumba. Lapho uthenga i-drill rig, kufanele ucabangele ukuthi imodeli ihambisana yini ne-drill rig oyidingayo. Cabanga ngokucophelela bese uzama ukukhetha umenzi onokwethenjelwa onekhwalithi ephezulu yomkhiqizo.
