Pasi pegomba dth sd mishoni 6 ”sando uye mutengo zvishoma
Mune mamwe maapplication, senge kudhirowa kwenheyo, sando dzeDTH dzinogona kushandiswa nekamwe kadiki mumakomba saizi kusvika .750 mm (30″).Iine akawanda sando mayunitsi CD (Cluster drills) chera makomba anosvika 70 ″ kana 1778 mm.
Sekutonga kwechigunwe, gomba diki dhayamita rinogoneswa nesando yeDTH ndiyo saizi yayo yezita.Sando ine masendimita mana ichaboora 4 inch (102 mm) gomba.Iyo inomisa iyo dhayamita yekunze yesando, nekuti, sezvo gomba dhayamita richiderera, kuyerera kwemhepo kunorambidzwa.Hukuru hwegomba rekugadzira kuchera saizi yezita pamwe ne 1 inch, saka pasando ine 4 inch hukuru hwegomba i5 inch (127–130 mm).
Kusarudza nyundo yakarurama kunonyanyoonekwa nehukuru hwegomba uye rudzi rwekuumbwa kwedombo.Sezvineiwo, saizi yesando inofanirwa kuenderana nechiyero chinodiwa chegomba zvakanyanya sezvinobvira, zvichisiya nzvimbo yakakwana yekuti zvicherwa zvibude mugomba.
